I keep my boat about 2 hours away, and at the end of last season I was in a hurry( I know) and apparently forgot to drain one of the sides on my merc 233. I found this out yesterday when checking up on everything and noticed my freeze plugs lying in the bilge. If the block is indeed cracked and I have to go through all of the trouble of pulling the engine again was thinking about a stroked 393 or 408. Anyone have experience with this conversion, is it simply changing the crank , would this be too much for a pre alpha?
thanks
