    OK I'm ready to hoist the 1986 Evinrude 90hp power head from the rest of the unit. Will the block "stick" to the base as I lift it off. In other words will I need to hold down or rock the power head as I'm hoisting to get it to separate?? Just need to know what to expect as I've never done it...

    When rebuilding an outboard, is it required to polish the crank or service it in any way before assembly??

    Polishing Heads During Rebuild??

    When I clean the heads of carbon, etc., is it necessary to polish the surfaces? I was thinking of just using a fine steel wool and thoroughly cleaning with a solvent to finish up. Attached is a picture of the starboard side on a 1986 Evinrude 90 hp outboard. They appear to be in pretty good...

    What years will a late 80's 90HP Evinrude factory trim unit fit on other units?? I have a chance to get a great price on an outboard that needs a rebuild and it has power trim on it. Even though the motor needs work, it has a great trim unit assembly. Can someone tell me what years, HP, and...
