Two bladed or three bladed prop ?

Lukey · 07 February 2007, 19:03

I picked up a absolute steal of a outboard off ebay ( £37 ! ) it is a little 5hp longshaft and it is perfect for what I want, the thing is there are quite big chips in the prop ( 3 bladed ), it is plastic. The thing is I also have a two bladed 3hp engine and the prop is metal.

I was wondering what the difference would be if i put the two bladed one on the 5hp ( ie speed, stability etc ) if any. Or is that dangerous and stupid ?

What make are the outboards?

Riiiiight then, death on the thames, here I come.

One is a evinrude and the other is a force outboard.

They are tranferable ( I have tried it ), just not on the water.

I think I will give it a little go in the bucket, and do a unscientific experiement to see which one can fling water the furthest.

Don't-you'll break the bucket and bugger the impeller using the 5hp.

If you put the prop from the 3hp on the 5hp you'll overrev.

what Nos4r2 said would the most likely outcome.
