Suzi 90

I have managed to get a brilliant deal on on of these for my 5.8 m Destroyer. Anybody using one on a boat of similiar size to get a prop pitch as a starting point?
The engine comes with a choice of prop so I would like to pick a pitch somewhere in the right ballpark as a starting point and work from there when the boat is built.
The hull will be fairly heavy as it will be fitted with large A frame and double console and fuel tanks (100-140L) plus aux and all the usual c**p!

I would start at 17"

I had a 90HP on my Osprey 5.25 which is quite a big boat for its size and that performed well giving me 36 knots at about 5300 RPM.

I would start with a 19". I had a 90 Suz on a 5.75 rib and ended up using a 21" as it was a fairly light boat.

You could also try Colin at Ardoran Marine - just down the road from you. He has loads of Soozook stuff and I think the DF90 uses the same prop fitment as the old V6 2-strokes?

I ended up getting a 19" as a starting point. It shouldn't be far away from correct.
I have spoken to Colin as he will be servicing it when it arrives, Ardoran is where I normally buy all my bits and bobs for fitting out.
He will getting hit for fuel tanks and electrical bits soon when the hull arrives....

prop size

i have a 5.5mtr humber rib with a df90 on it . we carry 6 divers and 6 lots of dive gear + an cox the rib does 22 knots on the plan with an 19inch pitch prop. i tried an stainless steel prop which was only 13inch diameter instead of
14inch and we lost steering control and push from it. use the suzuki props the blades are bigger!!!
