    150 Hp 2 stroke Optimax will not run at low idle.

    Was not a warm test since starting is a problem. Heard from the mechanic and he assured me that he went thru the engine and that it had 95 - 100 psi on all cylinders. Both oil tanks are full and sealed. There is not a low oil alarm. If the oil injector pump was not working, would there be an...

    150 Hp 2 stroke Optimax will not run at low idle.

    Finally quit raining. Did compression test. Results: Starboard side top 71#, middle 72#, bottom 71#. Port side top 81#, middle 76#, bottom 85#. Neediness to say I was shocked since the mechanic I bought it from told me he had gone thru the engine and fixed everything that was needed.

    150 Hp 2 stroke Optimax will not run at low idle.

    As soon as it warms up some I plan on starting to go through the fuel system to make sure everything is clean and OK

    150 Hp 2 stroke Optimax will not run at low idle.

    I got the part Installed it—still the same problem. The fuel filter canister looks like it hasn't been changed in a while. Should I check the fuel system? It will try to start when the throttle is not advanced but not start. Will start when I open it enough so it starts at 4000 rpms. I can then...

    150 Hp 2 stroke Optimax will not run at low idle.

    The man I purchased this motor is a Mercury mechanic at a boat dealer and he told me he had completely reworked this engine and everything was good. He said the problem I am having is caused by a switch located close to where the throttle linkage attaches to the motor. I previously sprayed the...

    150 Hp 2 stroke Optimax will not run at low idle.

    Just recently got this one. Will start and run at fast idle but when I reduce it, it dies. Had a mechanic tell me that a Optimax will do that but it has a part to allow it to keep running. Any help sure would be appreciated. It is a 2011 model 150 Optimax.

    1990 90 hp Mercury. Beeping when key turned on.

    This is a project boat. Been sitting for a few years. Will start but not stay running. Thinking carb kits. However the biggest problem is a beeping when the key is turned on. I’m thinking low oil alarm but there is oil in the tank. Am I on the right track? Should I remove the tank, dump the old...

    Shift problems, 2004 50 hp EFI

    Shifting is stiff, especially when going into reverse. With cables disconnected from the engine, they are easy to move. Manually shifting with the cables disconnected is pretty stiff and I guessing that is why when they are connected shifting is so difficult. Sometimes when shifting into reverse...

    Restoring a 1984 Johnson J60ELCRE 60hp

    Have this 1984 60 hp that has been sitting for 3 years. Everything seems to be working OK up to the carbs. (Compression is 125 psi on both cylinders.) Both carbs are type IV (?) and are not adjustable. Not all of the nozzles are in place so I have ordered new ones. Problem, one of the high speed...

    84 60 hp Johnson carb overhaul

    This motor has been sitting up for 3 years and I want to get running again. Pretty sure the carbs need cleaning, etc. Is there a good place to get the cleaning / overhaul procedure?

    2002 Nissan 50 TLDI over revs and slows down when trimmed up past center.

    Service tech said from cavitation but this started about a year ago and getting worse. When I lower the motor it stops. Recently installed a Humminbird hi def transducer. Previously had a standard compact ducer. Would that cause that? Before the compact ducer I had a DI ducer and don't remember...
