Author Topic:   84 Yamaha 40 Lower Unit Won't Come Off

I've been restoring a 74 13 Whaler... The engine, a 84 Yamaha 40 needs some work. The lower unit however, is fused on, especially at the back right above the trim tab.

I'm afraid of too much pressure because the housing is slightly corroded and may possibly come apart from too much pressure... I've tried some MILD heat with no luck.

Any sugguestions?

Not sure on that model but many (most) engines have a "hidden" bolt under the trim tab... remove the tab completely and look carefully for this hidden bolt! Happy Whalin'... Clark... Spruce Creek Navy
