    yep, you could be using it as a kicker or as the main motor on all different size boats

    Water separater filter options

    I would think a clear one you can see into with a drain would be a good idea myself.

    Engine bogs down under load

    I would guess someone else was backing the trailer down the ramp and the op was in the boat, started the motor once the lower unit was under water

    low compression #2 cylinder - 1988 suzuki dt85

    without good compression in #2, it will not light off and burn as it should n the cylinder. So it dumps fuel and air into the exhaust where it mixes with the hot burning exhaust of the other cylinders and finally burns. causing the noise you were hearing

    Engine bogs down under load

    might explain better why you were running the motor when backing into the river. was the boat still on the trailer at an angle? and was it back at the same angle when trying to load it back up? if so maybe you have water in the tank and it is picked up with boat at an angle

    check to make sure you have a good ground so the switches can kill the spark before it goes to the coils

    df9.9 runs for 5 seconds

    thanks for reporting back what the problem was. But I still do not understand how that would have affected just one cylinder, with only one carb for both cylinders.

    replacement carburetor for 89 Suzuki DT15c

    good luck finding one for a motor that old new, but you might find a used one, but no telling if it would be any better then what you already have.

    2002 Yamaha 200 HPDI. Appreciate any help

    HPDI motors drop 2 cylinders when in neutral, and will drop more if RPM is raised while in neutral. Make sure the ECU see the switching into and out of gear properly. should be easy with the laptop and software. But I would think the different shops have checked everything with the laptop. IF...

    df9.9 runs for 5 seconds

    well that is strange. if only one carb, then I do not see how it could be a fuel problem unless an air leak happens or maybe a leaking fuel pump could be dumping too much fuel into just #2 somehow. BUT since this is a 4 stroke, I do not think that would be possible. I would hook up a timing...

    df9.9 runs for 5 seconds

    does it keep running if you throttle up some? does pumping the primer bulb help to keep it running? I know nothing about that motor, but some motors adjust timing and enrich fuel during start up. timing is easy to check with a timing light, but I have no idea if or how that motor would add...

    Tricky Yamaha C85 Electrical Problem - 1 cyl OOS - Problem Rolls with Stator wires but new stator - Same issue

    Boscoe posted good info on how it all works. what you call the stater is the low speed and high speed charge coils. were you testing them at different RPM to see if they made spec in manual? you need to post what the specs are along with what you are reading, even for the pulser coils. It is...

    2003 Z250 Overheating

    if the PCV is stuck, there is a very good chance that the motor has a lot of mineral build up in the cooling passages. pull the stat out and inspect the passage and test the stat while you have it out. might need to use a chemical descaler to remove some of that. and hope that also allows you...

    low compression #2 cylinder - 1988 suzuki dt85

    just rig up a hose to the pipe heading up to the powerhead that the pump normally hooks to and turn on the water before starting what was holding the powerhead from coming off?
