Evinrude 150

I am rebuilding my 1978 Evinrude 150 and have a busted cylinder sleeve. Can anyone tell me which year/model powerheads are compatible with mine? 1978 model number 150849.<br /><br />Thanks

If your crank is still usable, it might be worth sleeving one cylinder.<br /><br />Describe "a busted cylinder sleeve".

Getting the crank "mic'ed" this weekend. I thought about sleeving but was wondering which year blocks would interchange just in case.

Whats wrong with the sleeve now? Cracked across the exhaust port bridge?

Actually a connecting rod bolt came loose and took a small chunk out of the cylinder at the bottom. Maybe the size of a dime. It's at the very bottom and nowhere near a port. Piston and cylinder wall have one large groove, maybe too deep to bore.

Re: Evinrude 150

Any "flat back" V6 crossflow will work. Around 82 or 83 there was a depth change in the by-pass area. If you use a block from then or newer you will need the by-pass covers from that block.<br /><br />Good luck!
