    What does the choke do on a Suzuki EFI??

    why is it starting and running OK if the IAC is stuck in the closed position? How are you trying to sending Electricity thru it? It is a stepper motor, so you cannot make it work properly by just giving it 12 volts.

    1996 Yamaha 15hp rebuild

    If that motor has the pressed together crank, the rods are part of the crank assembly. if nothing is wrong with the crank rods, and pistons you might get by with reusing them. what bolts did you break, and can they be drilled and timeserts or helicoils put in and still get your old motor up...

    Yamaha F80 Drive shaft Collar

    what are you pulling the driveshaft out of. where is this circlip and metal collar located maybe it is a driveshaft bushing located inside the upper housing #23 & 24 if so it should be lubed every time you put the lower unit back in. the drive shaft should just slide thru , no binding or...

    Yamaha 115 ETLK wiring

    did you miss what Boscoe wrote on that? is there a wire that will need to go to ground to cut the engine off? White is the Yamaha colour for the kill circuit. How does the choke work on this motor? Is it electric? Blue is the Yamaha colour for the choke solenoid. Solenoid activated electric choke.

    it would be best to look up the part you are talking about so you can call it by proper name and show us what it really is with a pic

    Clicking noise in neutral

    most lower units are spring loaded into forward, which means the linkage needs to compress the spring to get to neutral and reverse. so if the unit only makes the noise in neutral, there is a good possibility the linkage is holding things too far out of neutral to clear the clutch dogs. I...

    1984 Yamaha 25 hp SN No Spark

    do a web search for CDI electronics trouble shooting guide. it will give you the basics on what and how to test the kill switch ground the spark voltages to stop the motor/spark. that is where I would start looking if you have good peak voltages out of the charge and pulser coils

    Using hose flush to cool engine.

    have any of you looked at the size of the tubing that the hose screws onto to put water into the motor? not much water can get thru there for cooling. it is fine to use it, but if you want to run the motor, also use muffs to add water and lube the pump

    Suzuki 140 1995 Outboard Spark Plugs

    I believe the 5 is a hotter plug, keeps from fouling as quickly, but may cause detonation/pinging (fuel being set off before the spark happens)
