o2 Yamaha 4 stroke trim issue

[R Stewart]

Hi Just installed a new trim pump on a 2002 yamaha 8hp four stoke. Old pump bench tested bad. Have power from switch to motor. Ram will move by hand about 1/2 way but is spongie...??

Motor runs, but ram does not? Sounds like it needs to be bled?

Bleed

Thanks Dennis Not sure where tobleed. I open the fil screw and can lift motor by hand. Fluid comes out on up stoke only. Any tips??

I'd have to check my manual, myself, to see the actual procedural step-by-step. But for my setup ('00 250HP OX66), I think it's something like... trim the motor up and put it on the rest, then open the manual release and fill. Trim down and up and repeat. I would 'assume' it's something similar for yours, but that's not guaranteed.

I Realize the wind is free and everthing else outta be.
but now you need to find a dealer.
preferably one with some actuall trained techs.
that system was funky and there have been some updates and parts changes along the way.
