Contra-rotating propellers

[adrian dwyerParticipant @adriandwyer19693]

Could anyone suggest where I could get a pair of contra-rotating propellors from

26mm diameter, 2 blade, with a 3mm shaft. Its the 3mm shaft that seems to be the problem.

These are for a fast electric boat.

All suggestions are very welcome

Hello Adrian

I was involved in high speed motor boats some time ago and had the same requirement

It appears that handed props for high speed are not available………Just LH only

LH props will not unscrew themselves, going forward and may be a safety issue?

Here`s my setup…….

Both props are LH and was not a problem
