Hull Vibration?

[P3FE]

Just took out my boat after restoring it for 2.5 years. Ran fine, but there is a vibration I feel in the deck- a high frequency...the motor and outdrive seem to run fine...it can be felt in the windshield frames, and the bow storage access doors hum...it is a 1999 Bayliner Capri 1954....really haven't felt that vibration before...any ideas?

My money would be on ujoints, does it get worse with rpm?

Re: Hull Vibration?

no it does not get worse with rpm...I am going to relube everything and see what happens. Also going to pull a sample of outdrive fluid to make sure it doesn't have water in it. I slightly overserviced the square bottle reservoir. The vibrations seemed to lessen as more time went by.

Re: Hull Vibration?

Now that everything is solid....... you feel everything. Did you remove the motor and outdrive? Are they aligned properly?

Re: Hull Vibration?

I did not remove the engine or outdrive- I did remove the lower unit for an impeller change. Strange isn't it?

Re: Hull Vibration?

I also listened to the outdrive when we were in the water and there does not appear to be any strange noise coming from it. I am hoping it is just a dry bearing or something...plan on relubing everything and see if it goes away...you can feel the vibe in your feet...but then it began to lessen. I am crossing fingers it is nothing because my wife has had enough of this 2.5 year restoration project. I did not reinstall foam below the deck either. Maybe that vibe has been there and I didn't notice before.
