1966 Evinrude 18hp

I have a 1966 18hp with a cracked gear casing, I can get a 1969 gear casing for $50. The question is will it fit?? It looks the same, is there something inside that is different? Also what do I do about a gasket since this is no longer available?

Same gearcase , change out both upper and lower.-----.----Most shops would have the seal between the halves on a 50' roll.----Or buy an 0-ring and cut to make that seal !!

Thanks your a lifesaver! The previous owner was not kind to this poor motor. He even jb welded a homemade cavitation plate with a dozen sheet metal screws on it. I think there is enough drag from the screws to off set the benifit of the cav plate.

Are you talking about a "whale tail" that attaches to the anti-cavitation plate? Maybe a picture would help.

Yep it is a "whale tail" or hydrofoil. Found a brand new old stock gear casing for $50 so putting that on.
