If he puts them on the back of a 23' SeaCraft, he will have one F A S T boat!! maybe 75 mph.? They would have to be on a bracket with A LOT of floation! That would be one BA SeaCraft.

Last I heard they were over 800 lbs each.

My Seavette suffered from stern squat with twin 225s that weighed 720 lbs combined. 68 mph though.

He will need a half ton of flotation, a huge boat insurance policy, and should revisit his life insurance policy

Hold on - I thinks I hear ESD typing...

Nope, that's the 350 hp V8's at 822 lbs. The 300 4S is only 562 lbs.

Sorry to say guys but they may be going on 31 ocean master, not a seacraft. But would still like any info on these engines, if any.
