90 Rigger

[Walt Barney]

OK all you people who run 90 riggers I have a friend who needs to start runing his hydro with a 90 OPS and needs prop advise in both ABC and Octura.

Thanks

I've found a stock 1667 will make the boat hop bad, needs to be cupped up some?? ABC 67x114 is also a good prop S/B. B) B)

Good old 1667 w/5.8"-6.0"cup.

Like Ray said, cup will be needed to reduce lift.

1667 6.0 cup would be a great place to start. Just start adding tip cup to increase MPH.

I know of several well known racers, some of them come to the spring nats, that are running pitched up H-32's on their 90 riggers. H-45, H-48 and H-50 will work but need a strong engine to pull them. H-38 and 1667 also work well.

John's got a point, remember the OPS 90 was not a real RPM machine. B) B)
