Prop

After only the fourth time out with my new prop it looks like it's been fighting with the sharp end of an alligator, no idea what I hit except that I am pretty sure that it wasn't a rock as I wasn't anywhere rocky, maybe something else in the water as it did suddenly cavitate for no real reason at one stage yesterday, in about 30' of water.

It came from Oakley Marine and was a genuine Johnson one so may have been more expensive than it needed to be, think it was about 120 (ex vat) before the freight etc.

Is it worth getting a real el cheapo job or are the really cheap ones a bit rubbish, and what should one expect to pay for a decent but bog standard 19" pitch 3 blade alli prop? Or should I stick with the genuine article? I don't really know the ins and outs of props as far as different manufacturers are concerned and whether genuine or "big name" ones are better, I would have thought that one is much like another at the bottom end of the alli market but any thoughts would be appreciated!

Thanks

Stephen

Cool thanks for the offer - getting it here might be a bit of a pain though, it would have to leave from a UK container packing agent, what would it cost to get to UK? I was quoted 200 and something quid for a stainless one, reduced from 400 odd! I was also told that a 17" stainless is equivalent to an 18" aluminium one, but I didn't understand that? anybody got an answer?

Don't know if it will fit or not, will check the splines on mine tomorrow, how many has it got?

I've just ordered a replacement for the one I had - the same 19" alli - as I got offered a slightly discounted price which was very welcome and it was rude to turn it down

stainless is stronger than alu',far less flex, cuzz it's stronger blades are thiner and sharper on stainless, it will slice the water better.
but not sure this is an answer to
"I was also told that a 17" stainless is equivalent to an 18" aluminium one,"
maybe he knows the hull,
