1975 Mercruiser Tilt/trim issue

Look up a post from May 11 this year. The poster replaced his old style Prestolite pump with a newer style “Oildyne” style. I explained how to adapt the style with pipe fittings from the local hardware or auto store.
The only parts available for your pump are some of the electrical and none of the hydraulic unless you take a shot on used stuff.
As Bondo explained replacing the hoses is easy as he described. However if your hoses are good leave them alone.

Nope, there should be 2, 7/16th nuts at the bottom of the transom that hold the manifold in-place, removing 'em allows pulling the manifold down, to unscrew the inside lines,....

oh ok I did not know that I will have to take a look thanks for letting me know this
