How does that work on a trailerable boat. I am familiar with big boats that have seacocks to heat exchangers. Does the intake come through the drive or is there a seperate seacock in the hull for the closed cooling.
For 454/502 Mags, do standard ear muffs work, or is there a seperate intake for flushing on these engines
Forgive my ignorance, it just seems to me that my current 5L V8 is @ 1/2 the horspower, so the bigger engines seem to need more flow than the stern drive will allow.
Educate me!

Re: Engine Opinions
IMO, you will always be better off buying a fresh water motor than one run in salt. With that said, I always thought overall the 454 mag was a great engine. Again IMO, if you go with the newer 496, I think the HO is worth the few extra dollars.
It is not a big deal to flush the old 454/502 blocks. Muffs work, but make sure you run long enough that the thermostat is open so you get the circulation you need.

I was going to chime in that the 525s would be my first choice of closed cooling.
