I have a 1988 135 mercury.I have been told that the only difference between the 135 and the 150 is the carburetors.Is this correct?( larger venturis)
If this is correct .How do I make sure when buying a different set of carbs that I am buying 150 carbs and not another set of 135s?
I just took my 1988 mercury 135 to the repair shop because it would not idle.The shop installed a new stator.
It idles good now but rpms wont go past 3500 when pushing the boat.In nuutral it revs fine.Any Ideas
Thanks

My 1988 135 mercury .It cranks fine and runs great untill it warms up.Then it goes dead below 1200 rpms.If I push in the neutral botton and push the throttle forward it will start back up and idle above 1200.but once bemow 1200 it goes dead.The oil reservoir has been removed and i pre mix my gas...
When I was changing my poppet valve on my 1988,135 mercury.The old inner rubber seal that stays in the block ,fell inward in to the power head.

Thanks

I went to a local shop today.And the owner said the estimate is 2500.00 to overhaul my 1988 135hp.he also said it is common to bore only one cylinder if thats all that is needed.
Is this a reasonable estimate? And is boring only one cylinder common.
All my cylinders had 120psi on compression...
My 1988 135hp mercury ran hot when throttled up but would cool down when i was at idle.it had week pee. I was going to replace the water pump.The impeller looks brand new but i did find this broke plastic tube.Could this be my problem?
what is this tube for?

I have a 1988 135 mercury
All cylinders have 120psi accept #5 and it has 90.Is this to bad?
#5 cylinder is dead.I can remove the plug wire with no change in engine.
I have replaced the plug and coil.
It appears the cylinder is getting fire because it has fire jumping when I remove the wire.And...
I took my boat out for the first run since I bought it and it ran great, but a couple of times at 2500rpms it appeared the out drive was slipping ,the tach would go to 3000 with out picking up speed and it sounded as though the engine was out running the boat. It never jumped out of gear just...
This is my first sterndrive boat.When shifting into gear is a slight gear grind normal. The shift assist is working.And it shifts easy and has the red cable on it. Oh Yea it is a 1989 4.3 omc/cobra. <br />Thanks<br />Tony
The gimbal bearing was stuck and would not move even with the best of pullers on my 1989 omc .It was the factory bearing.I went and purchased a new bearing and measured the thickness of it.I then took a 3/16 drill bit and slid a rubber hose over it leaving only the bearing thickness exposed so I...
I just put jb weld on the outside of my manifold to seal a small crack caused from freezing.I ran my engine on the hose for about 15 minutes and shut it down a pulled the plugs a there was no water in the cylinders.I have a beam type temp gun. Do you think I could run my engine and if water is...
