Aftmkt Engine Insulation

[Four86Winns]

My Four Winns has this yellow sprayed on insulation under the hood, Although the engine runs fine and is generally pretty quite anyway, I'd like it to be even more silent. I've seen aftermarket insulation kits and was wondering if they work well. Although they do seem expensive. Can you buy heat resistant/ flame retardent insulation not specific to marine that would be suitable and far cheaper. I can't wait to hear more of that exhaust sound (due to the less of everything else sound)...

Dynomat is probably the easiest to work with.

Re: Aftmkt Engine Insulation

I googled Dynomat, and its some company in florida that features a similar product to Dyna-mat, Although i think Dyna-mat is more popular, as I've heard of it. Does anyone have experience with either products? Will it make a big difference? Do newer boats come with more insulation? Thanks guys this forum has been a great service
