Re: Mercruiser 233? with ford 351? ???'s
yes, pre alpha. However, pretty much everything is the same as the alpha aside from a few items of minor importance. There really isn't anything for the 233 Merc that can't still be found easily. There are only a few items that are NLA, but you can still find them easily online used (exhaust y-pipe, transom bracket, etc).
The 351w is an easy engine to work on and upgrade as well. Pretty much bulletproof like the 350. There's no reason not to use the 233 drive unless you just happen to hate Fords.
