Volvo DP noise and vibration

[Burtonair01]

So last fall my outdrive started to vibrate and make a louder than normal noise when turning to the extreme right or left, so I thought maybe the gimball bearing was going out or needed to be greased. Well my mechanic tells me after pulling it apart that I have voids on the transom housing from a bad bearing and I need to replace it, he says $4500.00 in parts and in order to do this you need to pull the motor!

Wow, any thoughts???

Funny...(not really) because that just happened to me with my 1995 Wellcraft eclipse 210 5.0FL. We were at the lake yesterday and i turned the boat around to pick up the wakeboarder and it started vibrating really bad and before i knew it i heard a pop come from the back and i quickly brought it to neutral....the engine was still humming. I attempted to put it back into gear and nothing...reverse...nothing. Not sure what i am looking at. Hopefully someone will jump in and asssit us. Good luck.

Atcra --- I assume you had to be towed in. When the engine runs but you have no drive at the prop. I would first look at the "rubber coupling" drive coupler -- that takes the output of the engine and transfers it through a splined shaft to the outdrive. Over time/misalignment, the splines inseid the drive coupler can wear and fail causing the problem you have mentioned. If you drive back slowly -- perhaps you have spun the hub of a prop. When this happens it is almost like a transmission slipping. lots of rpm, but little forward movement.

Buttonaire -- your problem sounds very different. At the potential money that has been quoted, I would have someone else look at the boat. "voids in the transom" seem to be a different issue, and I am not sure how the mechanic diagnosed this without a lot of disassembly allready.
