What's the biggie with the '86 motors that you want to see newer powerheads and how likely is that to happen?

Details are kind of sketchy at this point but I think they came off of a go fast boat and my pal wants to put them onbrackets on a big ole 24' Stamas.

I'm going with him tomorrow to eyeball the motors, anything to look out for?

86-87 had problems with overheating as they were a small bore engine(2.7L with a 3.5" bore compared to the 3.0L and 3.625" bore of the 88+. Same HP ou of teh smaller engine resulted in ALOT of powerhead failures). Your pic though is of an 88-91 style engine. Check the steering arms for rust, trim and tilt motors for rust and corrosion, and also look at the block for signs of where it has been welded. ALOT of the 88-91 engines broke reed valves and they would go into the crankcase and it would catch teh rod and blow a hole in the block. It isn't a deal breaker, but you have to make sure it was welded up properly.
