Props for twin V hull
 

Hi!

I will have two Merc 2.5 EFI SS engines mounted on my Phantom 25 offshore rig next month. The propheight will be 0,7-1 inch below the bottom. The engines will be mounted 19/20 inches senterline to senterline. The boat weight will be apporox. 2.900 lbs incl. driver. Estimated top speed 90-100 mph.

I have been reccommended to try Chopper 28 and ET 28 for top speed runs. But I am looking for options for good cruise and decent top speed as well, since the gasprices in Norway is awful (USD 6,5 per gallon...).

What kind of props would you reccommend; Bravo One 4 blade props? Merc Mirage props? Raker props? Hydromotive? Any ideas?

Cheeers! Toffen G

Toffen,

It is probably best to run your 3B props first and to email me with the performance data including the behavioral characturistics. I do agree with 375stinger in that Hydromotives may work very well on your application. They have 2 blade designs available, but I would really like your opinions, on her performance with the 3B, as this will better help us to dial your boat in.

I agree getting the base line will be an advantage.

Once this has been accomplished, there are some Turbo propellers from Precision Propellers I'd like you to try.

HI!

I will try to get hold of various props for tests. It is not always easy since the amount of props for tests are very scarce. I will test Chopper 28 and try to get hold of Mirage props.

What is the difference between The 28 Quad IV and Bravo One prop?

Cheeeers, Toffen G

Hydro QIV is a stern lifting propeller.

Bravo I is a bow lifting propeller.
