- Опубліковано 13 сер 2021
- 1988 150hp 2stroke Full service with WOT timing check and test run at the lake hit 45mph at 5500rpm 19 pitch prop steel my boat is a Invader 18.6ft open bow weighs 1350lbs no motor
I wanted to make a correction the timing should be 18 degrees at cranking speed meaning the starter speed and 16 degrees at full throttle meaning at speed on the water. I was corrected by a 25 year old veteran mechanic, I appreciate any help I can get learning these things.
Instant hard on these '80s Black Max's. Loved the sound at idle.... so nostalgic for me hearing it.
Love seeing these back to life, Just restored a 92 2.5
Yes that is one of the reasons I work on these motors so I can say I fixed and got it running properly myself and seeing the results is a reward in itself
@@haneysgarage2631 Are the 1992 2.5's oil injected?
Beautiful old Merc. That V6 has such a nice growl!
She's running like a top again. Great job!
I think all makers of this 150 class were very awesome, I marveled at all, the instant responses are catchy, can hear the RPMS revving like it can handle an extreme pitch prop, 😀 on the take offs impressive. I disliked Mercury but.... after watching this video, I now ❤️ all oldschool 2stroke motors ever made by all competing companies, great outstanding work, this would be my goto if I was able to hire him as a mechanic. I can't visualize the troubleshooting this guy does in his head dang. End result, I respect the 2stroke Mercury engines. I kinda knew who made the Mariner Magnums I loved seeing cruising by.
Man, I love the sound of those Merc’s
Loud, noisy and lots of smoke the best motors..
Can you show the actual process of setting the timing? Any tricks? Do you need two people?
Agree!
Lovely to see it acting and reacting like a beast! most engines nowadays are like clogged and not responding like this...
Smoooooth! nice work!
I Shore wish I had that engine on my Boat and YOU HAD A WHOLE LOT BETTER ONE
Hello, do you have a physical location? I have this motor from ‘84 and have an issue where it doesn’t want to go faster than 5-12knots in the forward position just past idle. When the control arm is further past half way, it sounds like it’s getting water boarded and dies. It wants to go faster but hesitates. Full throttle it gets Smokey and dies with smoke. Any help is appreciated.
i'm in Bremerton near Seattle
Also the white with a black tracer From the Idle module has to be disconnected from the outer switch box in order to time correctly, 40 yr Merc Certified Tech
I have a 96 mercury 200hp efi I have to check and possibly adjust timing. Do I need to disconnect this white/black wire from the outter switch box aswell??
@@matt98eclipse If it has a Idle control module then yes ,disconnect the white / black wire from the outer switch box
@@arthurtaddei1285perfect thank you!
@@arthurtaddei1285also! Sorry to bother you but I’ve noticed some people have ear muffs on when checking timing. Is this just to help the water pump propeller from getting hot?
@@matt98eclipse When ever the motor is turning over either running or with the starter ,water in a barrel or from the hose MUST be used To prevent Impeller damage or worse ,powerhead overheating
Amigo una pregunta compre un barco con ese mismo motor y tiene ese sistema de oil inyección no se lo voy a eliminar aun , vi que tiene un tanque de aceite arriba en el motor y otro con 2 mangueras de to del barco al lado de los de gasolina en cual se le pone el aceite en el que tiene arriba en el motor ? Y que tipo de aceite me recomiendas ?
so full throttle from idle is the same? No bogging?
Great video! I have a 96 mec efi 200 2.5 ? And need to check my timing! Will these steps work for motor??
Thanks i`ll look into it.
Hello,
I need help trying to figure out where the hose coming from “valve thermal air” leads to on that same motor. It’s the valve on the starboard side between plugs 3 and 5. Thank you in advance.
Is it possible to ad hydraulic steering to this motor?
@@wilsonjd69 Yes it is possible it’s just a spendy option unless you get it used
I have a question about mine. I have a 1986 skeeter with a 150 xr2 black max. It’s really hard to start on land or in water. Once it eventually starts it idles and runs fine. Revs up fine. In water it runs rough almost like it’s coughing. Everyonce in a while it will light up and take off full throttle or it will just fall on its face. I replaced stator, rectifier, and trigger. Didn’t help. Was wondering if the hard starting is due to my thought of the electric choke in the ignition not working?? Also wondering if carbs are dirty
Yea I would go through the carbs first then see if the electric primer is working by disconnecting it and use it to see if it works or could be plugged up
Sweet Eng
sweet sweet sweet
Before I cleaned the 3 carbs it ran great now installed and screw the idle so the motor rpm would lows down at idle... now a top speed its got no power and I get 10 mph maximum ???? 90hp merc 1989
@@jsboucher1883 if you mess with the idle it changes the timing you will have to set it up with a timing light and do the low speed pickup timing and the max spark advance timing while cranking the engine with the plugs out ground all the coils and spin over with the starter and hold against the idle stop for low speed pickup timing then hold against Wide open throttle stop and adjust to fit your specks in the shop manual
I like this engine but I like the inline 6 150 better. Towers of power.
The Tower of power engines are cool too I just haven’t come across getting ahold of one yet or worked on yet
@@haneysgarage2631 if I'm not mistaken, I think the inline 6 150 was the highest inline HP made by Mercury before the Black Max V6 motor you have here came out. The HP just went up from here in the V6 design. This one you have here screams on the water. It looked too fast to me going over wake. Boat was coming out of the water it appeared.
@@tommywatterson5276 I have hit 47MPH with just me on the Invader 18.6 foot open bow boat
Ther`s nothing NOTHING like the sound of the merc 2stroke!! Incredible engines. I love this video! I have an 89 150 blk max . Mine has a trim issue i`m working on . Is there a fuse or any underneath the cowl that can have an effect on the trim circuit? I know there are the solenoids/relays for up/down but any fuses?
I don’t think so but it could be the wires mine has 4 wires for the trim on my Mercury or ground wires corroded will make it loose connection
Might have to continuity check each wire
I really would appreciate it my name is Ernest Tapia I'm from California I have the same engine but I can't figure out the mapping of the bleed lines I just can't catch it on your video
I have a picture but can’t figure out how to attach it you can message me at360-710-1410 and I can send it to you
I have a 92 2.5 ,175 hp is the timing process the same as the 150?
Are the 1992 2.5's oil injected?
Agree the actual process of doing this would be greatly appreciated!
Very cool. I'm hoping to aquire one of these some day. Their sound is unmistakable. What do you run for a mixture since you eliminated the oil injection? Had an evinrude 125 thar had oil injection, but always mixed 100:1 in the fuel as an emergency just in case as I've seen more than one critical failure due to the oil injection system failing.
I do 50 to 1 on all the 2stroke motors I work on some older models require more oil but I haven’t worked on the older ones.
Where did you get the block off kit
I ordered it off ebay just a block off where the plastic or metal oil pump gear is with a seal but you have to disconnect the tanks and electronics for oil level sensors.
Where did you get your oil injection block off kit?
I got it on eBay Mercury oil injection block off kit remove the gear and install and disconnect the wiring.
@@haneysgarage2631 I have just one oil tube on a 175 black max that’s slightly kinked it might be causing an issue
I wish my 1987 would run that good. I have done everything that you have done but mine does not run that good.
Runs Good - Can I ask why you delete oil injection - Just curious to know if these models had problems or maybe just piece mind? I just purchased 2002 Merc 60hp & previous owner delete oil but not w/ kit just remove tank plugged line-At least on these models oil injection very reliable I ran any old one 20yrs.never an issue- Thanks for video-
I was having overheating issues and thought that might be an issue plus the previous owner put mix in the gas because he didn’t trust it so mostly price of mind
These old mercs have plastic crank gears and can strip causing the oil injection to fail. Very common to remove and run premix
I know my 1989 Black max 150 has the wrong prop on it because the locking nut does not go on properly, this is how I bought it. I plan on getting a new prop but right now my rpm meter shows 8000rpm at WOT, could this be right? If not, do yup think it's the sender or the gauge that is broken? It's also running at like 95 degrees C at WOT with new impeller, poppet valve and thermostats.
Oh ya yours might not be on the correct setting there should be a selector switch on the back but don’t continue to run it if it reading 8000 most are 6000 max and some 5800 and varies from engine to engine but some racing outboards will go 7000
Is there anyway to adjust the carb idle mixture screws you have the same motor as me but the screws on the carb doesn’t seem to be a control screw anywhere on any of them?
There is not an adjustment on the carbs just the timing settings
I’m stomped on my motor I went through the carbs and they are spotless I’m getting great spark all cylinders my reeds look great and the carbs are sucking air on all that’s why I say the reeds seem to be fine. Out the water starts idle and revs great all the way to 6k rpm in the water starts gets up to about 1600 rpms and won’t go on plane I’ve checked the timing and the full throttle timing looks to be off but I can’t really adjust it more there’s really no issue with the prop spins freely no issues with that so I’m really not sure if the timing would cause it to bogg in the water? Any advice helps you did a great job with your motor! Also I’ve been through the fuel system going to the carbs doesn’t seem to be any issues if any thing I think it just might be getting to much fuel fouling
Also the full throttle timing says to be adjusted to 26btdc and it looks to be at 20
@@truerudeboy1 ya it can definitely bog down if the timing is off that’s why I did it you will have to get a timing light and ground the coils to prevent them from burning up
What size and model boat do.you have that 150 mercury on ?
I have a 20 foot trophy series bayliner with a 150hp mercury and it struggles to get on plane. I'm going to try a different size prop this Saturday to see if it helps .
I would like to just sell the boat and be done with it . I just don't like 2 stroke motors.
I have an 1988 18.6 foot Intruder open Bow 14.5 by 19Pitch prop aluminum
@@haneysgarage2631 i have a 1982 Skater 18, about the same length as your boat but mine weighs 500lbs less, and i have the 2.5L 200hp, and for some reason it only goes as fast as yours with a 23P prop.. i think there's something wrong with my motor??
Hey, I have the same motor . What fuel do you use ? And do I need to mix the fuel ? If so what grade of fuel do I use ?
I have been using Super Premium Non Ethanol with yamalube 50to1
I have a Mercury 200 HP Black Max 1994 the alarm keeps beeping all the time when running and it cannot go more than 2500 rpm what could be the problem. i have already changed the water pump
did you ever figure it out?
You seem to know what your doing….I have the same motor 1988 black max 150 and I have the same problem plus when I try to plane out my boat the trim slowly slips back down. I assume there’s a leak somewhere but have no idea where. Beeb searching but can’t seem to find it. You think I could be the trim o ring?
I’m thinking it could be the o ring or one of the hydraulic hoses, connections or the pump itself check those for leaks and check level remove air out of the system might have to tilt a couple times to get rid of the bubbles
@@haneysgarage2631 you have an email or anything. The problem with my motor now is that it tends to have a hard time starting. I have to have the tilt all the way up so that it’ll start. I also have a pinched wire but don’t know what it’s for.
Why did it rev up real high in the beginning and sound like it was slipping?....my Blackmax xr2 does that sometimes too...spun prob bearing?
because I was a dummy and had the motor trimmed up too high for the run on video
You could see after it spun out I trimmed it back down and got on it again quickly
Did I screw up the timing ?
@@jsboucher1883 I’m not sure what happened to my last comment but yes you changed it
How how you rimming it with all the plugs out and not running? Just by getting #1 on TDC?
Running*
@@nathanwhitaker3712 I wasn't running it I was turning it over with the starter setting it up to set the timing all plugs out except #1 with the timing light connected so the plug sparks against the block during the timing setup
@@nathanwhitaker3712 yes also checked top dead center it was right on
I don't have the tool so I used a screwdriver and measured where the piston bottom and top strokes were and checked top dead center
@@haneysgarage2631 i will try this when I get home. I just bought the boat used and got it back home and it wouldn't get on plane I've changed everything just about on the engine I got a stator coming today . I've went through the carbs ,changed the plugs ,wires ,coils, rectifier CDI boxes ,trigger ,all the fuel lines from the tank to the carbs new fuel filter ,cranking battery.
@@haneysgarage2631 TDC is my mark on my flywheel supposed to be at 0 ?I pulled my fly wheel off with out making it to install the trigger and the stator.
did you do anything with the idle air jets after removing the oil injection. at 50 to 1 the mixture will be richer at idle. GORD
I haven’t really noticed but I assume it will smoke at idle and startups
At least more than normal
What did you do with the wires on the pick up on top of the oil pump housing? Looks like you tied them together I did my delete and didn't know what to do with the wire that went to the module.
@@nathanwhitaker3712 I had disconnected the 3 wires from the module and wrapped them with electrical tape and left them disconnected with the block off kit installed. let me know if it helps or need anything else
Did you started doing this as a job? I need someone to do mine 86 200 black max in New Jersey. :)
I am taking side jobs but I also work 6 days a week and have my daughter 3 days a week after work but I’m in Bremerton Washington near Seattle
This motor still available?
I haven’t been able to run it much because of problems with the boat trailer I’m trying to save up to get new leaf springs and u bolts they are cracked
I am going to sell it with the boat eventually
Can you send me a link to diy iol injection delete on a 96 150 mercury i cant find anything
im not sure where to find it i learned on my own and it took time to figure it out but i do show the block off points in my video not sure if its different on the 90s models but i think its close to the same
The seller did honestly not know that was an 88. I know because he set the timing the same as my 92.
Got it makes sense I should have set it to 18 degrees at cranking speed meaning the starter speed not WOT which would be the 16 degrees
Do you know if the 1987 150 has the same settings as your 1988
I’m not sure but I would think it would be the same
Of course as soon as I took it out again one of the coils went out ended up replacing all of them haven’t tested yet since
@@haneysgarage2631 my 150 will not run correctly at 11 degrees I have it set at 4 and it does better
There are 2 settings you have to make max spark advance and the water pickup timeing the 88 is 18btdc cranking speed max spark advance and 11atdc water pickup tube
cani get serial number and model number i need to get the reed and intake adapter this engine looks very similar to mines
my number is OB375096 Mercury 150HP
thats 2.4 liter right
No this is the 2.0 liter V6
they must have changed the heads.most two liters have the two piece heads
what size is the boat
It’s a 18.6 foot Intruder open bow

@@haneysgarage2631 Your local auto parts store should have 1/8 fuel hose. Like you I also used the clear hose at first however the hose shrank so much that over time it actually pulled off several of the nipples! That garbage clear hose gets rock hard too. I redid it with proper fuel line and 2-ear type pinch clamps. So much better.
