All that tension on one bolt and a bearing? You all got plenty of room to add meat to the back of that bracket in order to extend that shaft and add a second bearing. I see this video was made in 2012, so has there been any change to that configuration just like I mentioned?
Propellers are much more efficient at slower than 3,000 RPM's. My fan boat is turning at 3,200RPM and I'm told that a 2:1 reduction will allow the engine to spin much faster, making more HP, and a more suitable prop then makes things much much better.
@@repalmore but that only works so far too, before long you start having clearance issues as you said, or the propeller tips start breaking the sound barrier. But in the case of my fan boat, I simply need more engine rpm to get more HP. My plane has a constant speed prop which is great but not realistic for a VW powered fan boat.
These belts allow for a slight amount of slippage,...enough to overcome the power pulses of the engine. They also have greater surface area as compared to their width. (they also wear much longer than a cog belt would) The balls are squeezed and twisted in the operating mode to provide a means of setting the idler tension (they DO allow for a significant amount of shock absorbing as the belts stretch and recoil due to power loading - they do not provide for shock absorption from the engine power pulses as the belts themselves do that) Actually, I am quite impressed w/ the system and its relative simplicity - thus; why I am checking it out myself! (I am going to attempt to modify this system for a 2 cyl engine! (read HEAVY power pulse and much increased vibration - as they say, the proof is in whether I bust my (_!_) or not! :=)) )
Only a few strokes of the file ????. Really why did you remove the cloth// paper that you had in those holes and then show us how you filed the crankcases? Really ????????????
can you still purchase this kit?

How can I tell if my redrive is a type 3? It looks identical to this one.
Fantástic !!! Very good! Thank you Very much... Evandro Pedrosa from Brasil...
how do you order this kit?
Price please?
Let us know that price please?
Lube the seal???
Is the flyweel lighted?
Why would you want to reduce the prop speed on an engine that only turns 3k?
Propellers are much more efficient at slower than 3,000 RPM's. My fan boat is turning at 3,200RPM and I'm told that a 2:1 reduction will allow the engine to spin much faster, making more HP, and a more suitable prop then makes things much much better.
@@waynenocton In order to take advantage of the slower speed you have to either increase the length or cord of the propeller. If there is room, cool.

Is there a reason why they don't use cog belts? How much is a drive like that? Are the balls shock absorbers?

Have seen a few with cogged belt,quite good drive setup.Have seen some with chain drive and wouldn't recommend it.The V belt setup should work well.
