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.
Is this a problem? can the seal stop up the cooling,
Do I need to get it out? and if so .How?
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...
