3 blade vs. 4 blade

[henryfreston]

currently running an 11.1x14 pitch on tohatsu tldi 50hp on searider 4m. I am getting approx 5600-5700 rpm at WOT.

It's an aluminium prop currently.

Someone has offered me a bargain 4 blade stainless- it is also 14 pitch. He only wants £50 for it and its in good condition with no dings.

What performance differences will I see?

At that price , if it's ok then sell it for a profit. It's not going to be a lot of use on your boat-you'll probably be down by 400 rpm using it at a guess.

right ok I should make a decent profit then, it's off a honda 50hp.

It might not even fit then.

I'd still have it and ebay it though.

Ok will give the guy a call and have it (sounds like he just found it in his shed and doesn't know what to do with it).
