'79 Evinrude 150 Outboard Trim/Tilt Problem

[LarsonManta]

Hi,

I have a 1979 Evinrude 150 that will not move.

Two weeks ago I took it out for the first time this year, and had problems with the trim being extremely slow, and it wanted to stick in the complete up position. Unfortunately, I told myself that Id look into it when I got the time, and just ignored the problem. Yesterday, after a couple hours of flying around the lake, the motor was stuck in the complete down position. I managed to get it out of the water, pulled a couple pins and was able to lift it high enough to get it home.

The (pump?) electric motor makes the normal whirring noise, so I think the pump is all right. I am not sure how to fill or bleed the hydrolics, so detailed instructions would be great.

Other than the hydrolic fluid being low, what would be other causes for this? I am not very good with boat engine terminology, so please explain what certain parts would be.

Also, is there a place where I can download the manual for this engine?

Thanks,
Alex

Oh man you did it. People around here REALLY frown on downloading manuals.....


Tip it all the way up and remove the fill cap from the reservoir. Fill it to the top, run it up and down a few cycles, open it up, top it off. Do this a few times until it sounds right and doesn't take more fluid.

Do you see evidence of a leak?

Thanks for the response Fl_Richard. I went over nearly all the electronic connections, and found one of the wires corroded off. Fixed that and did what you said and its working great now.

BTW, sorry about the manual download question. Ill just have to suck it up and buy one.

Thanks again,
Alex
