Hi ,

Been reading this forum with lots of interest.

I have been thinking about the prop damage issue. A lot of noise on the web says if I run a stainless prop then I run risk of messing up my gears if I hit something. If I use a hub system then the hub is designed to sacrifice itself before my gears get ripped to shreds ?

There seem to be a few hubs on the market,
TurningPoint have their master guard(v 1 and v2), there is flo torq II and XHS (which are supposed interchangeable) and flo-torq III.
So if I understand things correctly, the flo torq II and XHS spin if I exceed some impact threshold and save me from major damage ?
The MasterGuard hub will distintegrate, but will it save my gears ?

What about my props ? If I am running aluminium I guess it will be bent but a stainless would survive ?


Is there anything else I should be considering ?

Thanks

James.

Well, since the advent of the rubber slip hub, I have been running that hub on alum and SS. I found that with the higher hp engines (125 in particular) I could hit somehting, at idle, as small as a submerged sapling and bend a blade; hence the hub didn't slip or if it did, too little, too late.

On SS I can only remember a couple of instances where I know I hit something, the engine revved temporarily, I cut the throttle, and returned to the previous throttle position and all was well.

I recently purchased a Hustler alum prop and it came with a new hub; a brass inner sleeve with a plastic (Walleyeyed says Delrin) sacirficial element.

It most certainly is sacrificial as the prop has spars sticking into the plastic, as does the brass inner liner.

If you hit something with that prop, either the brass will bend (permanently), the alum spars inside the prop hub will shear, or the plastic will be a pile of rubble.

Don't guess I need to tell you how I feel about this new invention. :|

They use the same hub on a littel 3.0 I/O as they due on a 6.2 MPI puttting out allmost 3 times the power

There really there to dampen vibration NOT save anything :)

Well initially, I think the case was to soften shifting stresses on the lower unit.....or maybe to not shear a pin when shifting into gear....!@#$%^& I hated those shear pins. :devil:
