Duo prop Bravo 3 on a Maxum 2700 Scr 4000kg

[Calle1756]

Hi!

My boat is soon finished and I need some new propellers. Anyone know what kind I need for my boat? It is about 4000kg, the 7,4 engine revs max 4400-4600rpm.
The Bravo3 is 1:1,65 I think, but I have to check that properly when I get it this weekend.

I'd like the Solas propellers, where the first propeller is 4 bladed, and the second is three bladed.

Anyone who knows what propeller I should have, or where I could look for an answer?

Use the Mercruiser Prop Calculator.

The Mercruiser Props come a 4blade front and a 3blade rear as well. I written a number of posts on prop calculation and size. I'd dig them up but I've been on vacation for the last 11 days and have too much to go through between here, work and home.

Best of luck.
