Sound proofing/Engine Noise

[gb387]

Anyone tired anything to quiet engine noise from our rotax engines especially the twin engine boats? I am thinking about adding some sound deadening like dynomat or similar.

There was a thread on here not too long ago about someone doing this to a Speedster.

Maybe I posted the question, I know I have been thinking about doing something?!? Thought I did, but couldn't find it.

Thanks for the link... Hoping for more sound proofing the engine compartment on 4 strokes.

Here's one thread I've found as I'd like to do the same with my 180.

There are others, but I can't seem to find them now.
