porposing at high speeds

[mptheriot]

Once again, still bouncing at high speeds! What to do?

[dmontzsta]

What kind of boat is it? and what kind of set up? I think that will help answer the questions.

[GofastRacer]

Yes we need info, what kind of boat, power, prop, gears,etc!..

73 schiada, 454 at about 550 hp, casale 41 gears, 11x 15 prop at 12 degrees Runs good approx 90 at 5500 accelerating strong then bounces must slow down! All suggestions appreciated

41 gears
Put some 18's in it that is way to much gear!!!
73 schiada 11x 15 prop
How many feet long? Two blade or three? is it a flatbottom?

[Moneypitt]

Yeah, maybe 25s would allow it to carry its weight throughout the speed spectrum......MP

we've got 18's in our little flatty with around 1000 ponies. It carries the nose nicely through the 1/4 at 8600. :smile:
Formerly owned a 20' Schiada with roughly 750 hp. The setup: 11 1/2*15 Menkens with 22 gears at 92 MPH. 6700 rpm. Never porposed.
You have way to much gear.
What's up TR2?

Mike,
Theres no way you could pull a 40 plus gear 5500rpm with 550 hosepower. Are you saying you have a 12 degree strut?
Try and figure out what you really have and post again.

Just hoping someone will give me a 11x16 CNC prop for my B-day.
