Prop Shaft

[gn7]

I've seen a strut like that on a 68 Aquacraft. I thought it was a neat idea but I would assume the part would'nt be as strong.

OH THAT HOLE. That hole has nothing to do with the strut bushing. Its actually a pickup for the engine water. Cool idea, saved drilling another hole in the boat before they started putting the pickup in the cav plate. It worked reasonably well for the power the made in the day. Nicson made a slightly different version than the one pictured, where the inlet was on the side of the barrel right where the blade met the barrel. It didn't feed water to the bushing either, but from the outside it may have looked like it did.
There was a cracker running that had the water pickup for the engine in the rudder blade. Series of holes drilled in the side of the blade on a forward facing angle, that connected to a hole drilled vertically down the rudder shaft. Cool setup, but I think they ditched it

I've seen some little sleeves that had a taper to the front that had holes drilled so water could supposedly pass through to the bushing. They only used two little set screws to hold them in place though. Can you get your shaft out without removing the rudder?

Yeah,I think Bergeron may have made those up. I got one that was on a used shaft I bought for the material. It would work better than nothing. But back to back speed runs didn't show ours made any difference and the bushings last so we I leave it. As touchy as the boat is to props and its location on the shaft, I would have thought it might jack with the handling of the boat as well. But Bill says it doesn't. Move the prop back a 1/8th, and sounds off like a little girl.

Djunkie brings up a question of extra drag from a collar. I have often wondered if there is aeriation from the strut or if a collar is used would it be worse? GN7 stated no difference in speed testing so maybe it does'nt matter.

Is there any meat to trim off the coupler?

You need to keep the coupler about a 1/16 or so off the v drive output housing, but the safety collar can be as close as you car to make it. It you don't want them to touch, fine. But I a couple thousands with a feeler gauge is all you need. Just don't let it touch the v drive housing or the shaft log seal. It will cook the seal in a heart beat.
Also. McMaster Carr sells SS two bolt safety collars that are only 1/2 wide if that helps.
