290 SC falling off plane
 

I have a 2006 Velocity 290SC with a 496 HO 1.50 Bravo 1X Dana 1000 tabs and a Hydromotive Q-IV 28 pitch prop. The prop shaft is about 3 inches below the bottom of hull. Top speed is 67 to 68 at 4700 to 4800 rpm. I'm having trouble keeping the boat on plane in 2' to 3' choppy offshore conditions. The real scary issue is running back in Sebastian inlet with an out going tide. I've tried running with tabs and drive in all different positions and no luck. Last time out I decided to hit the inlet with a little more speed between 30 and 35 gps mph drive all the way down and no tabs. About half way through the slop the prop started slipping and once again it fell off plane. I've been boating all my life but this is my first performance boat. Any help would be appreciated.

Try running it 45-50mph. Velocities run smoother when you run faster.

its the prop, try a 28 4 blade bravo labbed any questions give me a call Kenny 407-402-0300

It is your prop.

Kenny would know! He built the boat. Needs a different prop.

Too much prop. Call Kenny.

Thanks everybody. I bought the boat from Kenny earlier this year.
I guess I need to save my pennies and then call Kenny again.

Petty,

Try a Bravo 28- the Hydro QIV's have an edge on the top end but otherwise the Bravo prop will do everything else 4 times as well. FME- they suck getting on plane and cruising and the extra bump on top end isn't worth it.

As others have said, you need more speed and a better prop. I would recommend the "X" series of the Hydromotive props. I was having planing/stability issues with the Bravo that came on my 290 and switched to a Hydro P5X. Turned it into a better boat for planing, efficiency, and high speed stability. Didn't lose any top speed either!

I finally purchased a 28 Pitch Bravo 1. I'm pleased with the result. The wind doesn't push the bow around as much, It still planes off well and in high speed turns that would cause the Hydromitve prop to blow out the Bravo 1 slips a little and catches as soon as you straighten out. I did lose about 1.5 mph on top.

Thanks for the advice.
