Piston Assembly

Need assistance w/ tilt/trim seal replacement 1991 evinrude 50hp?

I need to install new seals and orings on the power tilt/trim unit of my 1991 Evinrude 50hp outboard. I am technically adept, but need to know special procedures and techniques (if any) to remove piston rod assembly, install seals, and reinstall piston assembly.

This is not a very difficult repair. Please invest in a repair manual for your engine. It will pay for itself on the first repair that you perform. Here's a link to get one.
