I noticed a "roar" when I started the boat yesterday. The boat ran fine, wasn't down on power, but as my wife described it, it sounds like a squadron of fighter jets off in the distance. I replaced the gimble bearing last year, so I don't think its that.
The sound resonates throughout the hull, so it makes it very difficult to identify where it is coming from.
Any ideas on narrowing this down would be greatly appreciated. Can I take the drive off and run the motor w/o screwing anything up? I figured that would help to rule out the motor or drive.
I have the 1987 454/Alpha 1 combo.
Thanks.
