jrd22 Sorry to hear of all the problems you are having with the new boat, some are to be expected but it sounds like you are getting more than your share.

I agree with Rockter, revving the engine in neutral will not tell you if it is a bearing in the trans. Even disconnecting the shaft coupling might not put enough pressure on it to cause it to squeal. If it is a bearing and oil sample should show some metal in it. That might be a good next step.

Rockter Yes, but the noise might be coming from the gearbox when in gear?
Disconnecting the final drive coupling and listening for squeal, or none, would confirm that.

I can check the noise in neutral ,run up the engine and I get no squeal. The shaft doesn't turn. So I know the noise isn't coming from the engine itself. Only when I am in drive does it squeal. As far as the warranty issue I believe it does say the warranty does not transfer. The issues I have with Marine Air is, they are supposedly a reputable company, it is a manufactures defect, and it happened before I owned the boat.

Rockter Boat ownership transfer has nothing to do with it. What did the warranty actually say?

Rockter Disconnect the final drive coupling to stop the shaft turning. Check for squeal then.

LakeEscape The little O-rings are called rubber grommets and you can get them at HD or Lowes. Buy the box of assorted sizes and keep them handy. Ranting is OK and it's free. Just about the only free thing with a used boat.

Melrna I found out what to use if the shaft is scored; Use 280 wet emery. The wet shouldn't be a problem when I pull the packing gland since the shaft will be leaking water. LOL! My real hope is that it isn't the front or rear bearings in the transmission. That will be a real bummer. The way to test it is put the shift lever in forward, If it squeals it is the front bearing (which mine does) and if in reverse it is the rear bearing ( which I don't remember if it does but will find out when I return to the boat on Weds). I did check the transmission fluid and it is good. What gets my goat is the engine has only 100 hours on it. This shouldn't be happening!
Since I bought this boat 6 weeks ago, I have had some major problems with her. I don't know why the sea Gods are so mad at me. First the engine was overheating. Found out Yammar had a recall on the engine water cooler mixing manifold. So I got that fix. Next, the stereo went out and now Sony has it and I should hear from them this week. The air conditioner had a leak in the cooling manifold. This cause the bottom half of the Marine Air to corrode. This was a manufacture defect. I got the AC fixed enough to work but only cools the boat to 80 degrees during the day. 1/3 of the evaporating cooling fins are gone. I am in a big fight with Marine Air and the extended warranty people to replace the whole thing. Marine Air, I was shocked they won't honor their warranty because of boat transfer ownership. My beef with them is this problem happened before I bought the boat and it is a manufacture defect that the previous owners didn't catch nor did my surveryor. Lastly my GPS antenna quit working due to a cut in the wire where it goes into the stern rail. So I ordered a new wire from Raymarine. I cannot find where to buy the little rubber O-ring that fits into the stern rail hole for the old one is shot. Ugggg...... OK I am done ranting!

jrd22 We have had a "sqeal' too from the packing/bearing/shaft. Sometimes it's at 2100 rpm, other times it's at 24-2500. Annoying because that is right about where we usually run the engine. We have checked the cutlass bearing thinking maybe that was the problem, it's fine. No increase in the frequency of the drips at the packing. This has been going on for several years so it doesn't seem to be a major problem. Hopefully just some kind of weird harmonics.

camaraderie If it is scored, then your new packing may not seal without over tightening and worst cast you may need a new shaft...but one step at a time.

djodenda Don't know how to deal with a scored shaft, but you can verify if that is the problem by running the engine in neutral... If it still squeaks, then it is not your shaft packing...
