View Full Version : Squeal and Vibration - NEED HELP!!!
03-15-2010, 11:07 PM
I took my 1999 Outback L/S out for the first time yesterday since purchasing it in Jan. About mid to full throttle I'm experiencing a squeal and vibration under the floor/engine bay cover. It is not constant, meaning that it only does it intermittently. The belt is a little loose and I thought that maybe it was a issue with the alternator bearing possibly going out, but I don't believe that would cause a vibration that can be felt. It seems to get worse under load such as turning or choppy water. It has no effect on the performance of the boat that I can tell. I'm planning to take it in to get checked/fixed, but I would like to hear some ideas on what it could be so I don't get shafted at my local marine shop.

You should be able to tell if it's the engine or in the drive line. If it's the engine it should be easy to find. If not, I suspect strut bearing wear or maybe the packing not lubricating correctly.

This is all greek to me. What is the strut bearing? Also, is there an alemite/grease zerk on the drive shaft? I'm use to atv's/utv's and it sounds much like a dry bearing.

Your drive shaft passes through a strut before it gets to the propeller. There's a bushing in there that can wear. Your shaft passes through the hull. There's a packing that is actually lubricated by the water and should drip just a bit (unless you have a newer "dripless seal". Do a search on "packing" on here and you can find out all about it.

Hopefully your drive shaft is not bent. Maybe your just out of alignment?

Ok I don't believe the drive is bent simply because the boat did not do this when I test drove it and it hasn't been in the water since then until now. The alignment was mentioned by a friend, but once again, alignment should be fine as it didn't do it when I test drove it.
Kaneboats... when you say that the seal should be dripping do you mean that it should drip water while on the trailer?

Should drip when the boat's in the water, running.

Ok I got it after searching and reading. Could this cause a squeal and vibration? According to the older post it is possible. The reason I ask is because I am taking on more water than should be normal and it now seems that maybe the packing seal needs to be tightened after reading and better understanding things

Just about anything could cause it. A lot of water is a telltale sign though.
