quick question
hello all, new to the board and looks like a good place for info...my family owns a 1987 21' sea ray sorrento that, because the mechanic that winterized it last year screwed up, had the engine break down....so, seeing as i have build numerous cars/motors in the past (mostly fords) i am trying to find info on rebuilding the 350 chevy mercruiser motor in the sea ray....just curious where i can find a shop manual on the boat and if anyone knows a good place to find chevy marine blocks (short or long makes no difference) block doesnt have to be anything fancy just a stock replacement or something close...it has and alpha one (i think thats what it is, not bravo drive) sterndrive....thanks for the help zak

Re: quick question
Amazon sells these manuals for std. Mercrusier powered craft, there are the actual mercrusier versions and then the 'Clymer' type that are similar. If you go the route of the 'official' mercrusier version ordered from the factory, you will need your engine serial number so you get the correct version.

Re: quick question
On the subject of where to get a short or long block.
I had great luck with a place here in Ohio when I repowered a 79 wellcraft Nova 21 with a 260 merc (350 chevy)
I spent about 1300 bucks including the core charge, delivered to my house on a pickup truck, sealed and dipped in shipping lube. It's a four bolt main marine long block with a double roller timing chain and bored out to .30--- getting a long block was cheaper than I could have done the heads and the valve work myself... and they did a good job. No funny noises, broke in fine.
I just used my existing sheet metal, pumps, and starter from the old block.
I have had three seasons on it now. It's propped out right, and will do 4600 wot no problem, still pulling from 4000 to 4600.
I did an aluminum intake manifold, a comp marine cam, and a mallory MBI ignition system to get rid of the points. But other than that, it went back "stock like."
