    2005 Yamaha 70B running rich

    check that the prime start heater unit extends the needle when 12 v is put on it for s few minuets which should close off the extra fuel needed only during cold start and make sure the fuel pump diaphragm and prime start diaphragm are not leaking fuel into the crank case causing too rich of a...

    RPMs out of control

    what do you mean it seems way faster now? boat moves faster across the water? or just motor RPMs seem higher when it revs up sometimes while under a load? these Yamaha's are normally spring loaded into forward, and have to compress the spring to go to neutral and reverse. you need to find out...

    2009 Yamaha 15hp 2 stroke pull cord problem

    if you are positive the start in gear preventer is not the problem I would pull the spark plugs if removing the plugs helps the motor to spin free, inspect for water intrusion. another thing to look into is the lower unit locking up. drop the lower unit to see if that will allow the motor to turn

    2018 Yamaha 25 hp. 4 stroke will not run at slightly above idle.

    sometimes a heated sonic cleaner is needed to get everything cleaned properly. sounds to me like the off idle ports have a problem

    Backfire from exhaust

    so why not post up what all 3 cylinder compression readings are now. there is a good possibility, that washed out cylinder was harmed from the extra fuel if this was not a premix. you are throwing bits of info out there and then come back and say that was not really true. not much can be...

    2013 Suzuki 15HP add charging Coil

    not sure on zukes, but Yamahas call the the coil that drives the spark the charge coil. lighting coil is what run the lights and charges the battery may just need a rectifier regulator if you have a lighting coil already

    Backfire from exhaust

    did you follow the link and sync procedure when putting the carbs back on? It includes setting and checking the timing to be sure it is in spec and advancing as it should with a timing light. check you fuel pump to make sure it is not dumping fuel into the #3 crankcase. backfiring in the...

    Yamaha, 4-stroke Mid Range Power loss

    timing light will tell if timing is in spec and advancing as it should and it will show if spark is good when problem shows up. could be off idle ports are dirty, so has a hard time transitioning to upper RPM. heated sonic bath cleaner may be a good idea

    1998 Yamaha 9.9ELRX won't rev up past idle?

    do you have a timing light to see if timing is in spec and advancing as it should? correct compression, spark, timing, and fuel to air ratio are needed to run properly

    1998 Yamaha 9.9ELRX won't rev up past idle?

    All I have is make sure the fuel pumps are in good shape and not leaking into the crankcase, and make sure the timing is advancing as it should

    Thermostat housing hole.

    my rig is high enough while on trailer that I leave the motor down while trailering and have not hit anything yet. I have Power tilt and trim so motor does not move. yours would be interesting to see where you could hook onto the trailer with a saver. I just looked again at your last pic when...
