    Ytrim1 Yamaha trim cap tool

    Wondering if anyone has had the chance to use this tool yet. Trying not to destroy the caps if possible.

    Ive had some air trapped in the trim rams since I've had the motor. Its looks like one of the caps has been replaced by the previous owner. I've done every trick in the book to get the air out. Thinking of pulling the caps and evacuate the old fluid. Then filling the lower area with fluid up to the bottom of the treads and reinstalling the rods and caps. Then rebleeding the system.

    You will fully tilt the engine and flip the lock lever before you touch the cap,it will fall on you. If you have the spanned wrench it's easy. The caps are right hand threads just turn CCW to loosen. I don't know if you will accomplish what you want but it's possible.

    I'm not sure if it will fix the air problem either. I've done the 5 count up and down. I've done the tilt up and fill till the the tilt hits by pass. It's just air in the trim rams..I can trim down perfectly with no issues. Trim up and it makes the gurgle noise until it clears the trim rams..tilt works perfect up and down. If I lock the motor up then trim the rams down they gurgle going down but work perfect going back up.. stumped at this point.

    Have to tried trimming all the way up and then releasing the pressure relief screw to allow it to bleed down? This usually does the trick. If not trim up and release the fill cap a little and let the over pressure bleed out.

    About 100 times..Its always done the trick..But Not this time. I'm stumped...I did notice that the trim cap on the right side has been replaced. I just notice that once trimmed down the rod does not retract all the way flush like the left side. It sits up may 1/8 of an inch. wonder if that's what the problem is. Thanks for the response..

    I haven't owned one yet that doesn't make noises going down. Once you bleed it out, run it and keep the res full. CJ

    I am just about at that point now. I might be just a little OCD.

    Mine does the same. Had 3 different places look at it and bled it until I got tired of messing with it and no change. The shops all say this is normal for the HPDI motors. Hope you figure it out and share.
