    Stator?

    Issue solved. Thanks Dukedog for the manual. The specs from the manual confirmed my stator was good, and the wiring diagram helped me rule out anything that may damage my new rectifiers. Installed the new OEM rectifiers and it works perfectly. Lesson learned, after market parts can save...

    1995 yamaha 200 hp v6 2 stroke trim tilt motor

    Removing the entire unit, with the motor off the boat is a preferred method as the other posts have suggested. It can be done as I suggested without removing the engine but may not safe enough time to make it worth it. if you have access to a cherry picker or chain block to lift of the motor...

    1995 yamaha 200 hp v6 2 stroke trim tilt motor

    If you can tie off the motor in the up position, unhook the top of the ram from under the power head (can’t remember if it’s held in with a drift pin or c ring) loosen the manual screw (on the trim unit) to manually push the ram down, then you can tilt the trim motor back a bit more to reach the...

    2008 yamaha 150 no start

    Test you motor ground. When you confirmed 12v to your starter solenoid did you use the motor block as the ground? Bad ground on the motor would cause your symptoms. If bad ground, the negative battery lead connection on the battery is often a culprit. Make sure it’s clean. When you say the...

    Stator?

    I have a Mercury 150 EFI 2 stroke. The tach stopped working prompting me to look at the rectifiers. They were both shot. I replaced both rectifiers and ran the motor at an idle. My multimeter confirmed the voltage at the battery increased when the motor was running and the tach was working...

    Yamaha temp gauge

    I have a 2006 Yamaha 9.9 four stroke. The layout of my boat does not permit me to see the motor from the helm. I had a plastic bag or kelp cover the water intake while trolling and the motor heated up, it was undetected until I heard the motor reaction to running hot. To avoid the motor ever...

When I unplug the pink wire off the signal buzzer and re test the yellow wire has...

    (Model F25ELPT, serial 0r374682) With thermostat cover & thermostat removed as well as lower unit off I can't get water to flow up the water tube. One of the ports under the thermostat cover seems to be blocked as well, I suspect a blockage around the top of the water pipe causing the issue...

    Force Timing Advance

    I purchased a used 1996 120hp force outboard. After 6 months of use It started running very rough. I found it to be a blown head gasket. After replacing the head gasket it ran perfect except for the fact that the idle was now increased to 1100 rpm. After ruling out control linkage and carb...
