Shakes and Shutters-Steering Wheel Issue

[CDAWaves]

When pulling up a surfer with enzo sac mostly full I am getting feedback from the steering wheel. It will shake pretty violently and makes a lot of noise. The steering cable was replaced this past spring. Any ideas of what would be causing this vibration and noise? It happens when the rudder is straight or turned but is more pronounced when it is turned one way or the other when pulling up a surfer. It does not happen unless there is ballast and the more ballast the worse it gets. This is an 05 24V. Is there some sort of adjustment. I searched the forum with no results.

Sounds like you have cavitation from the loaded up boat. Does it happen with no ballast? Does it go away when you get up to speed? You might want to look at a new prop, a new prop will get you better acceleration with heavy weight but it might take away some top end speed. If you can get on plane and can live with the shakes then you probably don't "need" a new prop.

May also look at play in your rudder. Might be time to replace it.

It only seems to happen with ballast and only for the first few seconds of pulling up a rider. The shake in the wheel and noise from the wheel is significant though. How do you diagnose play in the rudder? The prop does have some minor damage but wouldn't think it would cause such vibration at such a specific time?

It is your prop. Mine did the same thing with a ding that was almost invisible to the eye. Major vibration at launch an went away at speed. Get your prop repaired and I bet it goes away.

X2. The damage to the prop is causing the cavitation at launch with heavy ballast. The prop is not able to generate the trust that it could if it was undamaged. You can send the prop back to acme to get repaired and/or get a new prop too and save this one for a spare. If you go the route of buying a prop call acme and talk to a sales person, tell them everything a out the boat, how you use it, how much ballast, altitude (2300' for Hayden) and they will recommend the best prop for your situation. Way better than ordering blindly from a catalog.

CDA,

Is you boat still fitted with the stock 537 prop? Dings in the prop or not, It sounds like you are experiencing prop slip. With that amount of ballast and the boat listed over, its easy for the prop to suck air (cavitate) as well.

Yes, I believe it is the stock prop. I think I will get this one repaired and keep it as a spare and look into a new prop to handle the ballast we are running. Nearly all of our time is spent surfing. Thanks for the feedback. I was a bit alarmed because the wheel shake and noise is significant.

Ewok, do you know of any good prop repair places in the area?

Thanks again!

I'll check my business cards I got from the last boat show but I think there is a place in town. I'll let you know.
