Haynes & Hellyer Gears Wanted - 10% approx

[Bob Vic]

I'm after a set of smaller gears to suit my Haynes & Helleyer Z drive gearbox in Rebound. Current gears are too tall so looking for something around 10%. Call or SMS me on 0418 101 626 of PM me - whatever is easy. Thanks Bob.

25% & the prop is I think 11x 14 - not to sure on the prop but I will check & let you know.

So Bob are you trying to speed-limit the beast to <70mph? That's got to be a good thing...I might consider another ride

[bootlegger]

bob you sure you have 25 %. I think you will find they are twenties.

Bob I think mine are 5 or 8 and prop that came with it is 16x12 or 11.5

Darren, are you getting involved in this? we might have a round of musical gears.

The prop I'm running on Rebound is 11 1/4" x 16" - just checked the Prop Scan sheets. This is a Ron Hill stainless steel 2 blade prop with medium size blades. Gearbox is stamped in the ratio area 25 21. I know the top gear does have 25 teeth but from the photo I can't count the teeth but it is definitely small and could well have 21 teeth... so you could be right Dave 20% overdrive.

Bob thats the same as mine and if you turn the top drive one rev the out put is about 8% more rotation , I thought that the stamps where the teeth numbers
