When powering up getting out of the hole,I am hearing a "thud" at the rear of the boat. I can not tell where it is coming from. Everything else is fine. Any suggestions? :confused:

Re: outdrive noise

Re: outdrive noise

The only other thing I can think of is a loss of pressure in the trim mechanism causing the outdrive to stray upon deceleration, then upon acceleration it slams back into the boat. Other than that, i'm drawing a blank...sorry.

Re: outdrive noise

what kind of drive? I'm assuming the boat is a maxum?

Re: outdrive noise

What's the make of the out drive. I had an OMC that had that problem, and it was in the gears.

Re: outdrive noise

Anything loose in the bilge? Ski locker? Anything that could slide back towards the rear of the boat that makes the thud? Is the noise every time?

Re: outdrive noise

Thanks once again for all your reply's. Make of the outdrive is a bravo 2 , make of the boat is a scr27 maxum 1991. Yes same noise everytime. Very hard to trace. Boat runs fine otherwisw. I will look for something loose that might be banging in the bilge when coming out of the water. (good idea). I will have someone listen to see where it might be coming next time i am out. I am on the east coast and the weather has been horrible....<br />thanks
