- Comparing the performance of the 3.3hp and 5hp Mercury outboards on the same Aluminium boat. Both of these outboards are built by Tohatsu in Japan, I love the smallerTohatsu (50hp and lower), great motors.

thanks for the comparison. it puts the electric outboard companies' "3hp" claims into perspective. the 3.3 actually moves the boat quite well!
That’s incredible that a 3.3 hp outboard will plane a boat. Thank You!
yes but that boat it's pretty much empty... add 2 other guys in the boat plus some fishing gear and then the 3.3hp will move the boat at 5km/h. Not by near enough to plane the boat, but good enough to move from one place to another in a lagoon.
the 5hp won't plane either if fully loaded, but will move the boat around 8 to 10km/h, and will endure a little better against waves
Wow... It's fast and impressive... I can literally see your hair flying... That's pretty awesome!!
From the looks of his hair, he may have pulled that trick one too many times.
I'm a boat guy , grew up with boats and motors , and it still impressed me how those little motors pushed that boat
So true, I have found the Japan built Mercury (really Tohatsu painted black with Mercury stickers) for the under 60hp are super powerful and reliable.
I am impressed too mate.

Excellent video mate. Going to hopefully grab a 5 hp Mercury real soon..... Your video pushed me in the right direction... Nice one. I spent decade's in the land of plenty. Best Country in the world., 😉
Get two stroke although I think they only come in 2stroke just more power
Just bought a Merc 5hp Fourstroke for my 12ft inflatable Bris. The motor is incredible, so smooth and quiet
I had a 3 hp Mercury. Great little engine.
This on a johnny bass would be fun
Thanks for the comparison. I’m going to buy a 5hp Tohatsu shortly, but notice Parsun is also popular and cheaper. Would be interested to know your thoughts on the Parsun if you’ve tried it before.
Fantastic spreed! I have a 12 foot fibreglass boat with a 20hp honda on it and I can only get to 25kph, maybe I need a different propeller? 🤔
Those 5's are awesome. What length is your tinny? I had mine on a friend's 10ft fg dink. It would get stuck at around 20kph. When I moved forward it accelerated to 24 and when I moved back again it went all the way to 28kph. Just needed that little c.g. shuffle to help it get on the plane.
The tinny was 10ft, it had a pretty poor hull design as well.

Thanks for the comparison. I have a 2.5hp Mercury on a 10ft alumacraft and not pleased with the performance. I will be upgrading to the 5hp.
Upgrade to 9.8
8hp 2 Stroke
Get anywhere from a 6 to a 15 depends where you are. In the creeks a 6 is ok but if you want to go the ocean get a 8hp or a 9.9 so you don’t have too much weight but enough power for the boat. If you’re going on a big lake go all out an get a 15. Plenty of speed for tubing but also if it breaks you don’t get eaten by a shark.
How much does your 10ft aluminum boat weigh? Thanks for the great video.
The tinny weighs about 45kgs and I had about 30kgs onboard, I am about 77kgs.
I thought the 5hp did pretty well.
Cheers
how do you think a 5hp with a 14ft boat will do with 3 men fishing?
What is the weight of the hull ?
Hey mate what size is your boat ?? I have a 13 foot Tinny I use to have a 15 on it but it seized I can only really afford a new 5hp 4 stroke do you think that would be ok
Hi mate,
That tinny is 10ft and pretty light.
A 5hp won’t go that fast on a 13ft tinny.
If your used to a 15, a 5hp will feel pretty sad. If your happy to put around then it’s up to you.
The 5hp I was testing was a two stroke so not too sure how the 4 stroke 5hp compares but probably similar.
I would personally be looking for a good 15hp second hand but like I said, if your happy to put around at about 12-15kph flat out then all good.
Hope this helps,
Cheers
I just put a riser bracket on the back of my 11' De Havelland Tinny to get the cavitation plate of the outboard level with the bottom of the boat. It absolutely flies with a 5HP when I sit in the middle of the boat like you do but it doesn't like turning at full speed now without Ventilating. Any suggestions? Also what is the height of your transom, mine is 17.5" now?
Hi mate,
I would lower it slightly. Another option is to add some cupping to the propeller.
Cheers 🍻
Aussie Boat Guy 😎
@@25hpboatracerman I have the option of lowering it an inch but I have a 3.3 I want to try on it first. If it has the same problem with both the 3.3 and the 5, then I will cut it down. Cheers.👍
Thanks!
Hi Champion
No problem!

Were you on plane with the 3.3
Hp motor. Kindda hard to see wats going on.

Can a 5hp motor pull 2-3 adults and 1 child ? Or atleast 2 adults and 2 kids?
Thanks for the great video, finally I have found someone compare between 3.3hp & 5hp with same person and same boat.
Interesting Indeed. You gave us a clear idea between of them.
However I have I question if you don’t’ mind.
Your boat how much does it weight roughly?
Again thanks for great video
The hull is 50kgs, I am 77kgs and safety gear and tank are about 25kgs so 152kgs without motor.

25hpboatracerman many thanks for the infos^^
I am new to boating. I just ordered a 14-footer PortaBote which has a max load capacity of 701 lbs. Can this 3.5HP handle a 570 lbs combined weight?
A 3.5hp will push it no problem, just won’t be fast.
I would say you may see 8 knots with one onboard and about 5 or 6 fully loaded.

I saw a comparison recently between (iirc) a 5HP and a 9Hp. The 9 whooped the 5, and the only difference between the otherwise identical motors, apart from the price, was the 9 had a bigger hole in the carburetor jet.
Hi mate,
Yeah, it’s good to know, especially if you have the 5hp version. I don’t know of any outboards that share a block between 5hp and 9hp but I know a few that share between the 5hp and 8hp and definitely a big difference in performance for sure.
Happy new Year 🎆
cheers 🍻
Aussie Boat Guy 😎
@@25hpboatracerman come to think of it, the two motors might have been 9hp and 15hp.
I have both of those motors Tohatsu branded. Also I have a Honda 4 stroke, and Nissan/Tohatsu 2 stroke motors, both 5HP. The Honda just chugs along at full throttle with my 3.500 lbs sailboat, the Nissan makes it fly, big difference. The problem is that in California where I live, is not legal to sell 2 Strokes anymore, and in Lake Tahoe, a beautiful lake in the Sierras, 2 strokes are forbidden altogether. Nurse your 2 strokes as long as you can
Absolutely, and well said, love the two strokes.
Hope we don’t get two strokes banned all together in Australia 😐.
Cheers 🍻
Just bought a Mercury 5 hp 4-stroke propane with sail power and turbo prop after considering other 2- and 4-stroke options, new and used.
how big was the boat?
Totally interesting - the 5 seems worth the extra!
Thanks mate, appreciate your comments.
The 5hp is definitely worth it, way better.
cheers 🍻

I'm just wondering if wé can use a lake hull in a salty water, i have a 21 feet hull with 200 hp purshassed in Canada and sent To be used in thé méditerranéen, is there any risk
Can’t see any problem as long as you wash the boat down and flush the motor after use.
Is it a aluminium boat?
Are both of the engines 2stroke or 4stroke???
Hi mate,
only one motor, 30hp two stroke.
cheers 🍻
Any info on the fuel capacity and running time on the little 3.3?
Sure,
The 3.3hp has a 1.4 liter internal fuel tank. I’ve found I get about 1hr running time out of that 1.4 liter tank if I’m cruising at about 4000rpm. Full throttle uses the tank up in about 40mins.
I just carry a 5litre jerry if I’m going any place when I will use more than a tank. Keep in mind i can probably get about 10 kilometers on one tank for a distance reference if the motor is on a small tinny or small inflatable.
Normally if I’m going far I take a bigger outboard, but it does still happen from time to time.
@@25hpboatracerman Cheers. I got one, then found out afterwards that the one i got has no gears! There's no neutral, just a direct drive to the prop
Normally only the 2.5hp has no neutral and is just direct drive.
The 3.3hp has neutral and reverse.
The only difference in the 2.5hp and the 3.3hp is a restriction washer behind the carburetor, so if it’s a 2.5hp you can just remove that if the want the 3.3hp.
Does your motor still have the model and serial number?
Cheers
I use middle also with my 12’ 5hp
Is the 5hp 2 or 4 stroke?
They are both two strokes.
Cheers
Il 5 hp è 2 tempi? Di che anno è?
CIAO
si due tempi
il 5 CV è stato costruito lo stesso dal 1996 al 2017 circa.

How big is the boat?
Hi Champion,
it’s a 10ft aluminium boat, pretty light too.
Cheers 🍻
Aussie Boat Guy 😎
.What size boat do you have?
10ft light aluminium boat.
@@25hpboatracerman Thanks👍
Great video!!
What's the fuel premix that I should use on the 3.3 hp?
Thanks
Thanks mate,
The fuel mix I use is 50 to 1.
So that’s 50 parts petrol to 1 part two stroke outboard oil - every 5 liters of fuel is 100ml of oil.
Make sure you use outboard two stroke oil and not just lawn mower two stroke oil as they are different.
Cheers 👌
@@25hpboatracerman Thanks mate 👍🙂

Hi mate,
My brother is asking me about the fuel mix on the 5 hp Mercury.
Is it the same 50 to 1?
Thanks a lot.
Cheers from Portugal :-)
@@Zenpalmelao
I use the same 50 to 1.
Check your exact 5hp model though to see what the manufacturer suggests.
Cheers 👌
Just buying my 12 year old a tinnie with same merc, 5hp. Think the tinnie is 10ft, yet to sight, buying of good mates elderly dad sight unseen. $750 includes trailer. In Tweed Heads Nsw. In NSW under 4 kilowatts no need to register boat, a 5hp is about 3.7 kilowatts. His age can’t do more than 10 knots . Anywa, what size of 5 hp fuel tank and what time/kms you get from it. Appreciate your opinion. Cheers 👍👍
Sounds like a good deal to me.
I’m in NSW so same rules here.
The 5hp Mercury - tohatsu normally has an inbuilt Fuel tank, some did come without the internal tank but all of them can connect to an external tank. You don’t need any bigger than a 12 liter tank. If you decide to just run with the internal tank (which is totally fine) I would carry an extra 5 liter jerry van onboard as well. The 5hp on my tinny reached about 15 knots with just me in the boat. The waterways authority and water police have not ever had an issue in my experience with speed if the motor is under 6hp.
If the boat has more than one person in it it will be considerably slower.
Hope this helps.
Cheers
Also forgot to say I was getting around 10km distance off one tank at full throttle from the inbuilt tank or around 25 mins at full throttle.
I think the inbuilt tank is 2.5 liters.
Cheers
Hey thanks for the awesome quick reply. Good info. Tried sending you a photo but didn’t seem to be able to here . We live basically on the river in a unit. Love the water, ocean, etc, I grew up sailing Palm Cove Cairns his age. Every day after school sailed and then all weekend. The Water, ya can’t beat it, it’s just magic. 👍😀
Cheers
Lol, my boy wants a 25hp on approx 3.5 tinnie. I think as mentioned above is a better option 😂😂😂
is the 3.3hp 2 stroke??
Yep, it’s a two stroke, and the 5hp is two stroke as well.
Cheers 🍻
Aussie Boat Guy 😎
So impressive how fast is the 3.3, mine is 200 evinrude
The 3.3 only goes 17kph, just slightly slower than a 200hp.
Still has its place though (dinghys) definitely not as exciting as a 200hp.
Cheers
Glenno
If anyone has 2 or 2.3 or 2.5 engine all made by Tohatsu if you remove large washer in carb inlet Voila you now have a 3.5hp Outboard....
Hi Chris,
Yep, you are correct 👍.
Cheers 🍻
Would have been cool to see the difference in speed with the 5 if you sat in the middle and the back like the 3.3
With the 5hp, sitting in the middle or the back does not really make a difference to the speed as it’s fully up on the plane.
The 3.3hp just doesn’t quite get there so sitting in the middle forces the nose of the boat down, leveling it out and slight increase to speed.
Hope this helps.
Cheers
Yep. This test isn’t accurate!
Good point mate.
I tried sitting on the middle seat with the 5hp, i actually lost speed by 1.7kph. I think I lost speed due to the front being pushed down while being up on the plane (skimming over the surface). The 3.3hp does not have enough power to get up on the plane (skimming over the surface) so sitting on the middle seat and dropping the front seemed to increase speed as I saw by the GPS read outs. Interesting that sitting on the middle seat with the 3.3hp increased top speed and sitting on the middle seat with the 5hp decreased speed.
Cheers,
Glenno
What speed?...knots, k's, or miles?
Kph.
Cheers 🍻
Hey how good are them one on fuel
Hey mate,
They are pretty good on fuel, not as good as a four stroke but I think they are good 👍
how long is your boat?
The boat is 10ft
I have a 102cc then manual says 4hp got it for free from a gentle man that said they haven’t started it in over 20 years
Great motors, carb overhaul, new impeller and most likely your set.

Hi mate,
If it a light 3.5m tinny with nothing much on board apart for you at 50kgs, with the 5hp two stroke I reckon you might see the same numbers.

Does anybody know if the 3.3 hp Mercury needs a mix of gas and oil in the tank?
Absolutely, it needs 50 to 1 fuel to oil mix. Make sure to use marine two stroke oil (not lawnmower oil that is designed for a different running temperature)
Outboard two stroke only!
Every 5 liters of fuel needs 100ml of two stroke outboard oil.
Have fun.
Ps the motor will only run for about 3 mins without oil and will cause enough damage internally to require a rebuild.
Cheers,
Glenno
The Aussie boat guy. Thanks a lot Glenno!
yes mix
Please en klmh ? Sorry i am french
Yes, that was kph. Kilometers per hour. Thanks
@@25hpboatracerman what is the consumption?
The 5hp can go about 10km distance on its 2.5 liter tank and the 3.3hp can get about 5.5km distance in its 1.4 liter tank.
I have 3.3 a full gives me 2klm where is the problem thank you
Not sure why your only getting about 2 kilometers.
What size boat is it on and how heavy? Did you measure the distance with a gps?
Distance on water is hard to judge without a gps.
How do I have a Honda 4stroke 5 hp on a 12 ft Jon boat and only go 6mph top speed I weigh 220 ?? Lol
I have a 5hp parsun 4 stroke on a 2.8m infltable dhingy and I go about 11kmh
I have 3.5hp Mariner (Tohatsu) on a 2.4m dinghy and i average around 20-24kmh. With 2 people on it slows down to 9-10kmh though.
I have a 3.3meter dinghy with a 2 stroke mercury 5hp and i go about 22
change positions on motor shaft
The 4 strokes are not just heavier, but never seem to be able to give the power they are listed at. A 5hp 2 stroke will in many circumstances feel twice as powerful as a 5hp 4 stroke. It also drinks twice the fuel of course! As for noise, well single cylinder 4 strokes can be noisier at speed than the 2 stroke.

Mercury made in japan :-)
All mercs 30 and under made in Japan, also branded as Tohatsu. good motors most of em'
