Ok I'm guessing I already know the answer and what needs to be done, but I just bought a used glastron gx 205 with 97 hours on the engine and although it is a 10 year old boat, it looks like new. I hear noises coming from the lower unit I'm sure during idle and slow speed, once I get the boat planned out I can trim to make the noise quiet until I make a turn and then I have noise again.

this boat was owned by a surgeon who didn't really take it out much, it was being maintained by a auto repair shop. So I have concerns that the lower unit has ever been removed and the u joints, gimball greased and inspected. I've never owned a volvo penta drive, always mercruisers, and I've been told they are noisy drives, and that the high five stainless prop on the boat could be causing my issue also. I hate taking this in during the middle of our very short boating season in Colorado, but I don't want to make things worse. Any advice would be useful at this point, and anyway to isolate the problem before taking it in the shop which I'm sure will be a long wait.

thanks, mrbill

These replace the SX drives in engine packages as of 2007 model year.

IMPORTANT NOTE: SX-A drives are NOT backward compatible with older engines!
You would need special adapters for your transom shield, exhaust couplings and electrical couplings if your current set-up is a PRE-2007 model. Call us if you want to attempt this conversion.

These replace the DP-S drives in engine packages as of 2007 model year

IMPORTANT NOTE: DPS-A drives are NOT backward compatible with older engines!
You would need special adapters for your transom shield, exhaust couplings and electrical couplings if your current set-up is a PRE-2007 model. Call us if you want to attempt this conversion.
You must call us to order DPS-A drives: (877) 621-2628.

Exchange drive units (one of our most popular items!) are remanufactured BY VOLVO PENTA and have the same one-year factory warranty as the new drives. Some drives are no longer available as remanufactured (reman) but we have listed the new drives to order below for your convenience.

Please read the following notes:

1) Core charges (for exchange drives only) will be returned to you when you return your original drive. Most drives ship UPS ground for about $60 (depending on your location). Put a thick layer of bubble wrap or foam around the drive when you pack it.

2) Core charges (for exchange drives only) will appear with a discount in the shopping cart, however, you will be charged the full price on all core charges. Our shopping cart is not smart enough yet to realize that core charges do not get discounted!
