Proping down 150 Opti

[Andy_Rs600]

Had the new boat (Ribcraft 6.3) out last week. The engine(mariner 150 opti) is off our old boat and is turning a 17P vengance. I knew we were going to need to go down as the new boat is a much deeper v with no planning pad.

I'm currently getting 4600RPM wot with the normal load of 10 divers and kit +2 crew, and 5600 wot one up.

I'm currently thinking 14P, anyone got any suggestions?

Buy a torqueshift 11-26". Solves the problem completely.

No one got any ideas? Does anyone know where i can rent/borrow/beg a 14P 14" diameter prop to try, otherwise this is going to be avry expensive guess!

There is an adjustable rather than variable pitch prop that might be worth a go-but it's plastic and a 4-blade. On the up-side, they aren't horribly expensive.

Unfortunately they don´t make em any more, great prop sold a lot of them in the past and still have some blades and parts left for them.
