79 Skier prop rotation
 
Does anyone know the correct prop rotation for a 1979 SnS 351W with the 1:1 BW tranny. I read the prostar history which stated the prop rotation "MAY" have been Right Hand. I'm and engineer MAY is not an option. I was curious to know what I might be getting into before heading back to the farm this weekend. All else fails I will pop off the distributor cap. Regardless of engine rotation the distributor on the 351 always turn counter clockwise.

Late 70's were a mixed bag from MC as far as engine/prop rotation goes, as far as I can tell. It seems Mastercraft MAY not have cared which direction they turned. Im sure they were not doing anything with the hull to compensate for the prop rotation anyways. CC didnt start doing this until 1982, and they had always used RH props on their direct drives, so they were a bit more mature in their design at that point.

Im not sure what youre planning to learn by popping the distributor cap, because as you state, the rotor will turn counterclockwise (regardless of engine rotation) on a running Ford Windsor.

Most MC's that I have ever encountered were LH prop rotation. Generally, must CC's are RH. TRBenj; have you seen a RH MC? Just curious....

There are early Mastercrafts with right hand props.

Pull the prop nut off and the prop will be stamped with size and rotation.

It certainly is a LH screw. I was curious because the poor girl was robbed and retrofitted by a showskier. I think they are worse than farmers when it comes to "making thangs work". Tthere is no telling what was put back in to fill the hole for the robbed parts.

LH rotation is good news since parts will be easier to come by. No reverse grind cams and such

Anyone know if the flywheel is 157 or 164 tooth version? Am I to assume that it is the standard 28 oz balanced version?

FWIW some 205's were reverse (RH) rotation as well. I have no idea which years. But they were supposedly subject to chine lock because of it.

I have... ~75-78 seem to be the years most likely to have a RH prop, based on what Ive seen. Earlier boats could be the same way, there just arent that many of them.
