What do you want to do-use the SR as a tugboat?

It'll slow it up IF it fits.

Assuming you can get one for the same size gearcase and get the right hub adapter there's no reason it won't fit.

I have raised the outboard again as the revs are still to low.
I was advised to get a 19p stainless prop and i have just seen a secondhand hi five on ebay and thought it would give more acceleration than a standard 3 blade ?

It will, but it'll reduce your top speed.

A 19p 5 blade will do less rpm than a 19p 3 blade. You're better off doing the comparison on like for like props and only changing one variable at a time.

You won't get any useful data from changing one prop, the way twins affect each other.
