I believe it's fresh water cooled. It's on a pallet and has supposedly been rebult along with the boat transmission. I don't need the transmission and he'll let the motor go for $500. Of course that could be false economy. I have a set of 69 440 heads and other parts from a car so I'm mainly interested in getting a good short block. Reverse rotation is no good to me.

Rebuilt for $500 ??? Treat that as a CORE, do NOT assume just because it's got a shiny paint job that it has been REBUILT ?? Also what pistons are in it ? It could be low compression ???

About 30 years ago I bought a beat up old flatbottom/v-drive that I got just for all the parts I needed for a boat I was building - exhaust manifolds, steering gear, v-drive unit, etc..it also had the "rebuilt" 413 referenced in my reply above. I never trust anybody's "rebuild" anyways, so I tore it down for a look-see. I found 2 finger-tight headbolts, and the 8-bolt flywheel was held on with 5 bolts and nuts, one of which was one size smaller then the rest and flopping around in it's hole. It was at .030" over, so I had it punched to .060", and it cracked a wall within a month.
No more backyard rebuilds or saltwater blocks for me.

How to spot right hand, or reverse, rotation.
Pull dist, look at the dist drive and cam gears, they will be cut backward compared to a left hand, or standard/automotive, rotation. This is so with the backwards spinning cam, the oil pump will turn in the proper direction. There may also be a thrust "spacer" to keep the dist drive gear from walking away from the oil pump, LH rotation pushes the drive gear down, RH pushes the gear up.
