I have a 1990 Force 150hp and I can't find the manual release screw for the tilt&trim...Dose anyone know where the release screw is, I have the book, but I can't find it anywhere in the book.
Most likely you don't have a manual release for the tilt/trim. Very few if any of the 1990 and later tilt/trim units for the 4 and 5 cylinder motors have a manual release.
If for some reason you can't lower??
You'll need to loosen a hyd. line.
Be VERY careful and use a line wench or you can strip the fitting.
I believe the first of the 3 in a row drops it. Not the one on the bottom.
Some people want to mess with the bottom part of the hyd. pump looking for a release.
Most times they end up buying a new one.
The motor not working???
