Been watching all your videos. Most Excellently Done!!! Thank you!!! Just bought a 2001, 70hp Nissan outboard attached to a 1983 whatever boat. Will be commencing some work on it this evening. Temp here in Arizona was 110 degrees this afternoon. I'm retired US Army and boat motors are completely out of my life experience. Just saying Hello and and expressing Great Appreciation for teaching how to work on these motors!!!!
These are great motors, I had a 30 hp that I ran on a 14' runabout. I ran it almost every day for years without issue. And my brother had a 90 Nissan that he used commercially for years also.
Thanks for taking the time to put this up here. I don't have a 50 hp, just an old M2.5A 2.5 hp, but I watched your video anyhow and KEPT watching because it was just so well done. It would have been good to also depict the whole carb adjustment process, but I still think folks with this motor will find your video very helpful. On behalf of them, thanks again!
Eric, I've been watching your videos for quite some tome. I just subscribed oday. I love watching you work on these boats & motors. You are very knowledgable for someone as young as you. You should be proud. I'll be watching! Thank you!
i bought tohatsu 50 hp everrun 2 months ago , 2001 and 2016 is almost same , reliable engine ,better you use 15 pitch 3 blade stainless steel propeller...... only regret i didnt buy the electric starter and tilt version ..... thanks for the video
As you tuned the engine to run on the muffs, you will need to redo the idle tune once you get it in the water. The back pressure on the exhaust when it is under water makes a difference to the idle setup. The 15" shaft, manual start engines are commonly used for the beach patrol/life saver IRBs (rubber ducks is their common name here) . The engines tend to have a short life as they are run up on the sand, get flipped over in waves and generally just get a hard life from being in salt water/air all the time. Your engine looks like it is a very nice buy .
Thanks for the info on this video. The only complaint is that you chose not to show us the adjustment to the carbs. To someone like me with very little mechanical experience I would like to have an idea of how much adjustment to expect. 3 turns, 1-1/2 turns..?? But the video does have lots of info.. thanks again
if you have an outboard, always get the service manual (factory, not seloc or clymer!). they will walk you though it. the key is to adjust all the carbs equally. ive seen people try to do them individually, and they won't ever run right if out of synch.
Great video! I've got a 2003 M40D2 remote steering set up with tilt/trim. Mine is a low hour motor, too. I've just been through the timing/carb linkages/2 stroke oil pump mixing adjustments. Also did the car idle adjustments. I really like this motor and would love to convert it to a 50 hp but the carbs and reeds are hard to find. Thanks and take care!
Great video this is one of the best video I have ever seen on this make of motors. I have one of these motors and I always wanted to clean the carbs and now I can. I wish you would of shown is how you adjusted the carbs but awesome video.
I just spotted mine has a broken top throttle cable tiller wonder if I can still use it until get a replacement Seems to still work one pulls and pushes
I adjust my 2 strokes Tohatsu 50 HP motor air/fuel mixture screws using a electronic vaccum meter, motor's vaccums are set to same reading, motor idles smoothly and evenly.
Bro I noticed you always have a cough in your videos. I am a nurse by profession. Do you have something going on or do you smoke maybe fumes from carb cleaners?? Just make sure you get that checked out dude if it continues. Just looking out. Hell it could be allergies. Like I said just looking out bro
I know this might not be realistic right now, but I would like to see a video on how you adjust the neutral gear setting. I have a Yamaha 25hk 2-stroke Autolube from -92, and I cant get the neutral position to be correct, it grinds a little bit and I have to hold it in neutral with my hand so it doesnt grind against the gears. Love watching your videos even tho I dont own anything else than a Honda BF75 and two Yamaha 25hk / 4hk 2 strokes. Cheers buddy!
Hi Eric, my 2004 yamaha 15hp 2 stroke tiller starts only when the throttle is on, and doesn't idle. If you drop the revs she stalls and takes a while to start again. She runs fine when she's above quarter throttle but under that it stalls. Any idea what is causing this?
Great video. Duck hunters love those motors on a Jon boat. I was always told not to put a motor in gear without a tub or bucket of water for resistance. Any thoughts? Also whats the value of a motor like that?
Hi I have the 90 hp automixingmodel works fine but the odd time it doesn’t start on my and have to use my auxiliary it’s cranks over fine new plugs abd clean fuel filter etc
How does your outboard prime your carburetors. I have a Nissan 30hp & just has a choke. I just purchased it & having problems tuning it on . Its also a pull start
Boating forums, boat mechanics, the commercial crabbing industry all agree on one thing.....Tohatsu has the best reputation for reliabilty, period. Parts availability is another question.
Hi I'm Mike I live in Houston and would like to get ahold of you to ask you about some of your small 9.9 to 15 hp short shafts I would like to by a nice dependable on from you how may I get in contact with you. Thanks
You sure it’s not just blow back of burnt off 2 cycle mixture? That happens with 2 strokes and it’s normal. Run your finger through it and smells it. Gear oil has a very distinct grease smell to it .
I have a old johnson and it was dirty under the hood an I went to my local parts store an picked up two cans of engine degreaser and it did wonders then I sprayed all the nasty away an wiped her down and she came out beautiful
Eric... Would running this engine 30 or 45 minutes on a high concentration of Seafoam treated fuel have accomplished the same results...? Lemme know. Thanks
I'm way late in the response but with a 2 stroke of unknown history it's really important to clean the carbs and install new gaskets. If one runs lean you'll sieze a piston and mess up your engine.
I have a tohatsu 40 that is 10yr old have had since it was new but I let it sit for a bout 1 yr cause the last time I went out it was running funny it would not hit its max RPM like it norm would so I put the boat up 4 a 1yr then took it to have its 1yr service an told them what I just said they told me it was the carbs so they cleaned them all I got it back went out and it ran good but it still wont hit its max RPM it was 6500 or a bit more now it only hits about 4900 and I just cant fig out what the hell it is if u have any suggestions it would be greatly appreciated?
Hey bud I’ve been a subscriber for a few years now and since I’ve been watching your videos you’ve came across a few 90 horsepower Yamahas and I’ve been looking for one for a while now and I’ve had no luck at all! Well not one that they weren’t asking full price for an! Could you help me out maybe?
Hi Eric :D i have the same engine but just with the electric startmotor and with the oil tank but i have some issues with the carbs on my engine but how did you adjust it ??? how did you do it ?? Thanks for your information
very good video, greetings from Argentina, I am a fan of the Tohatsu brand, I have a 9.8 an 18, a 30 and a 40 hp, all very good, the jewel is the 18 hp, all 2 times, what opinion do you have of the tohatsu brand you greetings
Hi Eric, thanks for those great insights and craftsmanship from you in US. I expect many Outboarder owners coming around to your workshop, eehh ?! I'm facing probs with my 70hp 2stroke Merc from 1982, motor razzles / dazzles and crankshaft drags somehow. I posted a Vid in my channel. What do you guess, is it required to fully disassemble motorblock ? thanks from Europe for all your contributions George
that block has always been cranky and under powered. they originally rated it at 50hp, then a VERY overrated bump to 70hp, then in 1986 when propshaft hp came into play... back down to 50hp. before putting $$ into that motor, do yourself a favor and find a big block 3 cyl 70, 80 or 90 horse version. much more power, torque and reliability. Just my opinion.
Please can you tell me about the propeller if the gap is big when we turn by hand. Because mine without mouve the gear the propeller, turns a quarter. Maybe need replacing something? Please if you know something about or any utube about or mechanical with our engines I thank you very much.
a jet ,is the most restrictive component in that passage, so blow it out without disassembly, you could have saved yoursaelf a lot of time and us , a lot of misdirection by just running the engine with air box removed and manually choking each individual carburetor to remove any imagined or other restriction, and then make the adjustments that you think fixed something.
Can you do something on setting carbs up? Adjusting mixer screws etc? That would be very useful.... Thanks!
Your videos give me just enough boating fix to last me until the weekend. Thank you
Been watching all your videos. Most Excellently Done!!! Thank you!!! Just bought a 2001, 70hp Nissan outboard attached to a 1983 whatever boat. Will be commencing some work on it this evening. Temp here in Arizona was 110 degrees this afternoon. I'm retired US Army and boat motors are completely out of my life experience. Just saying Hello and and expressing Great Appreciation for teaching how to work on these motors!!!!
This motor is exactly the same as my Mariner, only difference is mine has 20"
And it was in storage for about ten years. Thank for the tips Eric.
These are great motors, I had a 30 hp that I ran on a 14' runabout. I ran it almost every day for years without issue. And my brother had a 90 Nissan that he used commercially for years also.
If you have a air compressor it's really good, until the jet slips out of your fingers and disappears for ever into the garden bed.
get a strong magnet :D
Jets are brass.......
Thanks for taking the time to put this up here. I don't have a 50 hp, just an old M2.5A 2.5 hp, but I watched your video anyhow and KEPT watching because it was just so well done. It would have been good to also depict the whole carb adjustment process, but I still think folks with this motor will find your video very helpful. On behalf of them, thanks again!
Toyota’s in the driveway. What a legend
Eric, I've been watching your videos for quite some tome. I just subscribed oday. I love watching you work on these boats & motors. You are very knowledgable for someone as young as you. You should be proud. I'll be watching! Thank you!
That sounds like a dragster!! Awesome!
i bought tohatsu 50 hp everrun 2 months ago , 2001 and 2016 is almost same , reliable engine ,better you use 15 pitch 3 blade stainless steel propeller...... only regret i didnt buy the electric starter and tilt version ..... thanks for the video

Your engine looks like it is a very nice buy .
Ron Powell No IRB’s run 50’s. They always run 30’s or 25’s in Aus.
some years ago i had this engine but 25hp i had to sold it, i regret it til this day, totally loved it!
Thanks but I would have liked to see the final part of the carb fix
Beast of an engine. Zapcats and Thundercats rule.
I could also use a little bit of advice on which stainless steel prop to put on the motor?
So envy that you get all kind of neat newer motors in the area you live. Where I live, I have to try so hard to bid on junk motors for $$$...
I feel ya cali sucks hardly any water it's just a desert with high altitude
Thanks for the info on this video. The only complaint is that you chose not to show us the adjustment to the carbs. To someone like me with very little mechanical experience I would like to have an idea of how much adjustment to expect. 3 turns, 1-1/2 turns..?? But the video does have lots of info.. thanks again
Dunno but I'd check the impeller too. The water stream going out looks a bit thin
For sure. Impeller should always be done on a job like this, or after any period of extended storage. Even a brand new impeller will rot in storage.
Nice video, can you show us how to adjust the mixture screws?
if you have an outboard, always get the service manual (factory, not seloc or clymer!). they will walk you though it. the key is to adjust all the carbs equally. ive seen people try to do them individually, and they won't ever run right if out of synch.
Those are some bad ass motors. Here Louisiana something like that would go for 4500 to 5000
That 4 blade prop looks sick!
Great video! I've got a 2003 M40D2 remote steering set up with tilt/trim. Mine is a low hour motor, too. I've just been through the timing/carb linkages/2 stroke oil pump mixing adjustments. Also did the car idle adjustments. I really like this motor and would love to convert it to a 50 hp but the carbs and reeds are hard to find. Thanks and take care!
Great video this is one of the best video I have ever seen on this make of motors. I have one of these motors and I always wanted to clean the carbs and now I can. I wish you would of shown is how you adjusted the carbs but awesome video.
Just call the engine-company and ask! i did with my Yamaha 25hk for the mixture screws, easy money!
Very impress..
Im from Montréal.and i have a mercury 25hp 1983..i hope i will be able to fix it...continue your video.i love it!!
I have a 40 just like this. I love it !
I just spotted mine has a broken top throttle cable tiller wonder if I can still use it until get a replacement
Seems to still work one pulls and pushes
I adjust my 2 strokes Tohatsu 50 HP motor air/fuel mixture screws using a electronic vaccum meter, motor's vaccums are set to same reading, motor idles smoothly and evenly.
how?
you think that will fit on my 10ft john boat? maybe my 12ft v hull?
I can tell this one of your early videos just by your vocal presentation. You've come a long way!
Sounds awesome wished i could find a clean 40 version for my grizzly 1548...
150 lb 50 OMG a new 40 4 stroke 220 + love those 2 smokes!
what a beauty...
People in my country think very low about tohatsu and prefer a yamaha.
and how to adjust carburetor?
I will take a nissan tohatsu over any small motor
Great video thanks for your explanations when you do each step thanks from Canada
Bro I noticed you always have a cough in your videos. I am a nurse by profession. Do you have something going on or do you smoke maybe fumes from carb cleaners?? Just make sure you get that checked out dude if it continues. Just looking out. Hell it could be allergies. Like I said just looking out bro
I noticed too Dennial?
Bro we need more people like to tbh
Looks like lots of car fumes close by too.
@Phillyfishguy not this is a resperatiory problem
called smoking weed guys lolz.. taking hits in between scenes
Awesome video keep up the great work
I know this might not be realistic right now, but I would like to see a video on how you adjust the neutral gear setting. I have a Yamaha 25hk 2-stroke Autolube from -92, and I cant get the neutral position to be correct, it grinds a little bit and I have to hold it in neutral with my hand so it doesnt grind against the gears. Love watching your videos even tho I dont own anything else than a Honda BF75 and two Yamaha 25hk / 4hk 2 strokes. Cheers buddy!
Dose it go in reverse ok? Pt in forward and jumps out? Could be adjustment but probably clutch dog'
The fact he thought it was priming the motor by barley pulling the rope back lmao 😢 😂😂
Hi Eric, my 2004 yamaha 15hp 2 stroke tiller starts only when the throttle is on, and doesn't idle. If you drop the revs she stalls and takes a while to start again. She runs fine when she's above quarter throttle but under that it stalls. Any idea what is causing this?
Great video. Duck hunters love those motors on a Jon boat. I was always told not to put a motor in gear without a tub or bucket of water for resistance. Any thoughts? Also whats the value of a motor like that?
The value is pretty low In canada a new 50 is like 6k so this is about 1500 give or take so about 1k usd
Hey mate what’s the fuel air mixture how many turns out
which way did you put the emulsion tubes in ?
bullet proof engine
Wrong!! they throw rods at Idle, Garbage!!
You must have good neighbors around your place
How much did you buy it for and sell it for???? Profit loss????
Hi I have the 90 hp automixingmodel works fine but the odd time it doesn’t start on my and have to use my auxiliary it’s cranks over fine new plugs abd clean fuel filter etc
What type of cleaner do you clean your carbs with?
How does your outboard prime your carburetors. I have a Nissan 30hp & just has a choke. I just purchased it & having problems tuning it on . Its also a pull start
the sound of a 3 cylinder 2 stroke is something different
Defo. I am adicted to it. Got a 40 HP. Same engine more or less I think.
why is smoke coming out from the propeller ?
Back when Tohatsu was a good engine...
Which models are you having problems with?
Tohatsu is one if not the most reliable outboards in production fact
Boating forums, boat mechanics, the commercial crabbing industry all agree on one thing.....Tohatsu has the best reputation for reliabilty, period.
Parts availability is another question.
Are you here in Florida?
Eric I was wondering do you buy boat motors I have a old Suzuki tiller Handel 40 hp.
I was waiting to see it on your John boat running
How much was it? What did you sell it for?
I would like to buy that motor if it is available.
Do you still have this motor? Highly interested in buying
Would a fuel additive cleaned out that carb jet?....without the disassembly?
Not a completely blocked jet. If some fuel can pass through then an additive can work on it.
Hi I'm Mike I live in Houston and would like to get ahold of you to ask you about some of your small 9.9 to 15 hp short shafts I would like to by a nice dependable on from you how may I get in contact with you.
Thanks
Why no test ride?
I have a 1990 25hp 2 stroke nissan and just recently started leaking gear oil out the propeller, why is it doing that??
You sure it’s not just blow back of burnt off 2 cycle mixture? That happens with 2 strokes and it’s normal. Run your finger through it and smells it. Gear oil has a very distinct grease smell to it .
Can you show how to change the lower gear oil seal?
Great video. Thanks for the info. Im just starting work on a 2007 Mercury.
What do you use to detail under the cowling ?
I have a old johnson and it was dirty under the hood an I went to my local parts store an picked up two cans of engine degreaser and it did wonders then I sprayed all the nasty away an wiped her down and she came out beautiful
Can you do a video on a 150 Johnson about how to set the throttle and gear cable
How do you adjust the carbs?
Rebuilt 1991 Yamaha 150 , can't find no air gas mixture settings anywhere. Could you help me with this problem. Thanks Mark
Excellent service guys
Just curious why that motor has no choke plate on the top carb??
Doug McLean they are only choked on the bottom two, quite normal.
Hey buddy I got the same kind of motor but it’s a 40hp what’s up with the reverse stop cause I can’t put it in reverse?
Do you sell any of those motors
Eric... Would running this engine 30 or 45 minutes on a high concentration of Seafoam treated fuel have accomplished the same results...? Lemme know. Thanks
I'm way late in the response but with a 2 stroke of unknown history it's really important to clean the carbs and install new gaskets. If one runs lean you'll sieze a piston and mess up your engine.
It would but this one didn't run a minute let alone 30
Hi I’ll like to know if I could use a 90hp Yamaha outboard engine in a 20’ boat please let me know, I’m new in the boat stuff thanks
The boat has coast guard tag for power ratings length means nothing
Holy shit 50 hp tiller
Are parts readily available in the us?
Do you still have this motor??
I have a tohatsu 40 that is 10yr old have had since it was new but I let it sit for a bout 1 yr cause the last time I went out it was running funny it would not hit its max RPM like it norm would so I put the boat up 4 a 1yr then took it to have its 1yr service an told them what I just said they told me it was the carbs so they cleaned them all I got it back went out and it ran good but it still wont hit its max RPM it was 6500 or a bit more now it only hits about 4900 and I just cant fig out what the hell it is if u have any suggestions it would be greatly appreciated?
10:13 though he was gonna shoot the thing over to the neighbors.
You want to sell that engine?
Hey bud I’ve been a subscriber for a few years now and since I’ve been watching your videos you’ve came across a few 90 horsepower Yamahas and I’ve been looking for one for a while now and I’ve had no luck at all! Well not one that they weren’t asking full price for an! Could you help me out maybe?
Great video and very satisfying
Hi Eric :D i have the same engine but just with the electric startmotor and with the oil tank but i have some issues with the carbs on my engine but how did you adjust it ??? how did you do it ?? Thanks for your information
I dont think her gonna answer you
Her = he
nicolai you want to sell that motor
@thatboatguy I wish I could find a 40-50 hp tiller with 15in shaft!
Where do you live Zach? I have a beauty 40hp Merc SeaPro short shaft for sale. Up in Ontario, Canada though..
very good video, greetings from Argentina, I am a fan of the Tohatsu brand, I have a 9.8 an 18, a 30 and a 40 hp, all very good, the jewel is the 18 hp, all 2 times, what opinion do you have of the tohatsu brand you greetings
These are Yamahas.
Big hp tillers are very desirable
Hi Eric, thanks for those great insights and craftsmanship from you in US. I expect many Outboarder owners coming around to your workshop, eehh ?!
I'm facing probs with my 70hp 2stroke Merc from 1982, motor razzles / dazzles and crankshaft drags somehow. I posted a Vid in my channel. What do you
guess, is it required to fully disassemble motorblock ? thanks
from Europe for all your contributions George

I have a Johnson 6hp seahorse that won't start and I put new spark plugs and that's all I know to do to fix it....I NEED HELP
get the factory service manual. does it have spark and compression? getting good fresh fuel to the carb? what year is it?
Buy a new Jap Outboard
have this motors only powertilt or powertrim and tilt? i have the m40d2
Please can you tell me about the propeller if the gap is big when we turn by hand. Because mine without mouve the gear the propeller, turns a quarter.
Maybe need replacing something?
Please if you know something about or any utube about or mechanical with our engines I thank you very much.

Great video!
nice how much?
Can I buy a motor for a back up from you at your business
How much
Did you sell it?
Wayne Swicegood yes
This is the first 40/50 Tohatsu/Nissan I’ve ever seen that didn’t have electric start 😳
muy bueno los vídeo que he visto gracias
I have a tohatsu 9.9 15 but i need to do a servise om it
I'd love to replace my 30hp Johnson with this beauty.
awesome job :D on mustie1 channel he's got a drill bit set for carburetor jets to clean them out.
which video is that?
Awesome
Is four sale
U are young but sickening form vapours in being a mechanic can be very dangerous. Great engine buy. Johnnie
Sounds like its got A MEAN CAM....LOL 🤪🤪😜😜🤣🤣
