    1992 Mariner 200 EFI, lost power

    I have a strange problem with my engine. Sometimes I loose power, the 200hp feels like 5hp even with full throttle. If I put it in neutral I can rev the engine and think it sounds good. But with gear in there is no power. And then all of a sudden things are working, and I can get the boat to...

    Mariner 200 efi 1992 oil hose?

    Can someone tell me where this hose is supposed to go? As you see it's a T on the oil hose from main tank to small tank on the engine.

    Yamaha 225 -89 will not turn around?

    Found the fault today. Screews holding the bearing on the piston rod had come loose on one rod. So the screew went into the crank case wall and stopped the movement. The bearing itself is trash. Lucky the engine was at idle when this happened.

    Yamaha 225 -89 will not turn around?

    I was idling the engine home on a hose. Have started if a few times the last week, and thought it run fine every time. Running on pre mixed fuel even though engine have autolube.

    I'm sorry I see now that I need a peak voltage adapter to measure the voltage from the coils. Have to get me one of those.

    1989 Yamaha 225hp extremely bad spark

    Thanks, this is what I need. My cranking RPM is 220, manual say it should be over 250. First voltage from stator should be minimum 85V, I only get 15V. And next voltage should be minimum 25V, I only get1.5V. A new starter is ordered today. Hopefully that's the issue here.

    1989 Yamaha 225hp extremely bad spark

    I recently bought this engine. It has been sitting on a boat at the previous owner’s backyard for maybe 10 years and not used. And of course I can not start it. Have new plugs but almost no spark on them. Have only seen a very week (almost invincible) spark on two of the six cylinders. There is...

    Yamaha 90 2-stroke air hose?

    Here is the whole head with the hose plugged. I noticed that the colour of the cylinder part don't match head and intake. Someone might have replaced it back in time. There are two hoses going between intake, and one from intake to cylinder 2, should it be four hoses in total?

    Johnson 40hp 1995 overheating and rough idle?

    I’m having two problems here with this motor, think they might be connected. Problem 1. I cannot get the engine to idle properly, have done the link and sync process. Cleaned the carburetors and make sure there getting fuel. Spark is good on both cylinders. When giving throttle there isn’t...
