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

Dan Bell, the owner of the GN boat "Priceless", makes the tapered shaft safety collars with water passages in them. They are made in both left and right hand prop directions.

Now that think about it, that is who made the one I have. Never use it. I do have kind of a issue with putting dimples or flats in the middle of the shaft, so its never been on the boat.

do either of you have a picture of this ? or a contact of where to get one ? sounds like what i need

I was going to run this safety collar in front of the strut what do you guys think?

[78Southwind]

What's wrong with running a 2 piece in front of the log? I don't understand the want to dig set screws into the side of the shaft.

Nothing wrong with running a 2 piece in front of the log this would be in addition to the 2 piece in front of the log. I guess you could run a 2 piece in front of the strut too if you don't like set screws. What is the problem with set screws?

[ogshotgun]

I just don't think it's necessary, especially if it's going to be digging into the shaft with screws. And really those set screws aren't going to do anything but slide if something does happen, unless there are flats or spotfaces cut into the side of the shaft. I'm sure you guys don't want to do that.

Kevin i have a ? on mine since the whirl away was installed its buttoned up pretty tight i don't have the room for a 1/2" wide split collar with a 1/4" both sides.. so my only option is to use what is pictured but much nicer its a 1" longer and it has holes drilled in left or right hand to lubricate the bearing it runs a 1/4" in front of the strut..the shop that makes these says to either use a drill and make a slight indention or mill a flat.. please let me know i have no option

Danny Bell (562-577-3673) has long narrow tapered collars that are drilled with a series of tiny holes in a way that deliver water to the strut bushing so they mount close up to the strut barrell. It's really an ingenious design, and are not as blunt as the one pictured in the RexMar pic (sorry!!) and not likely to divert water from the prop. Heath Hiebert uses one on GN369 and it works great. I think Jim Wilkes sells them too.

Yep you right! Guess I really did'nt pay attention to it. This must have been a race boat since it's got a drop through strut.
