    Yamaha 130v4 2 stroke power trim motor

    no, you need to measure voltage to the motor. make sure the positive and negative is getting to the motor. you can also make sure you have good voltage getting to the relay, not just the control voltage causing the relays to energize

    Yamaha 130v4 2 stroke power trim motor

    hope you still have the original motor, it might be good also if the T&T relay is bad

    Yamaha 130v4 2 stroke power trim motor

    probably just the T&T relay not making good contact inside, test to see if you are sending 12VDC to the motor itself

    2012 Suzuki DF175A dropping RPM at speed

    I would monitor the rail pressure to see if that is changing when this happens/ if that stays steady maybe you have an injector acting up

    sure looks like Boscoe is correct. why not remove the 2 bolts holding it, then put it back do it right

    2007 3.3l 250hp starting at 3000+ rpm

    Heck, even my old 1999 C40 with 3 carbs did not have any chokes. just an enrichment system called prime start for cold starts

    2007 3.3l 250hp starting at 3000+ rpm

    injected motors do not use chokes

    2007 3.3l 250hp starting at 3000+ rpm

    I believe most of injected motors have Idle speed control valve that resets to 100% at shutdown to be ready for the next start. it should rapidly drop idle RPM once started if that control valve works as it should and there are no other places it is sucking in air

    2007 3.3l 250hp starting at 3000+ rpm

    I guess these readings are not while the motor was running. do they change when the motor is running?

    Primer bulb issue

    what does that mean? does the electric pump keep running as long as the key is in the on position maybe? I would not think that is what is suppose to happen, maybe it is sucking air instead of liquid fuel. but I know nothing about that old motor

    Primer bulb issue

    if pumping the bulb helps, I would be looking at the 3 fuel pumps

    Suzuki Kill Switch Issue

    even if the switches are working properly, the wiring back to the controller could be grounded in the harness somewhere

    Rotate Impeller on Occasion

    fire the motor up with water to the pump once a month or even more would be a good idea to lube and exercise everything

    1990 yamaha 250 2 stroke seapro 2

    L250 TXRS is a 1994 wiring will need to be visually checked , no way we can even guess what someone did to cross up the wiring

    1990 250 2 stroke sea pro 2

    looks like that is the TT and it is plugged up. maybe that ball thing someone rigged up should be swung over covering the hole to keep insects from going in the hole building nests and plugging the hole up. someone forgot to move it over during storage. just a guess

    2006 DF115 Stuck valves?

    if the pistons did not hit all of the valves to bend them, then it could be the cam timing has jumped and did not harm the valves. just need to get it back into correct timing

    2006 DF115 Stuck valves?

    good news so far. did cylinder walls look OK now pull the valve covers and check valve clearances, maybe too tight . or if bent too loose., I cannot think of much that would cause all cylinders to have low compression. if valves are good, all rings stuck maybe that one 5375 pic bottom right...

    2006 DF115 Stuck valves?

    bore scope would be a good tool to look in the cylinders. Should see if pistons hit the valves

    2006 DF115 Stuck valves?

    have you looked into the cylinders when you had the plugs out?

    Interchangeable lower units??

    running shallow with motor jacked up would be my guess
