Noise level

[jmccall001]

Not sure if this is the correct forum but here goes. My 1982 sea ray 260, weekender runs out great buty at over 2500 rpm it is LOUD. Any suggestions on quieting her down?

Hi,<br />Probably a reinsulation of motor room can help lower the souundlevel. 3M Thinsulate (Metallized film) is one alternative.

Re: Noise level

I run a 350 chevy on my OMC. I have had the same problem your speaking of. The boat used to have a 305. I removed the motor cover an all of the old insulation. I re-insulated it using regular builders foam insulation with the foil exterior, a silcone adhesive to secure the pieces, aluminum foil tape at the seams. The installation turned out great but the noise level did not subside as much as I had hoped. I think it's just something i have to accept. My boat it 34 years old but in great shape so I'll live with it.
