Conclusion
There are many different types of sound deadening materials that can be used for boat engines. Some of the most popular materials include foam, fiberglass, and lead. Each type of material has its own advantages and disadvantages.
Foam is the lightest and most affordable option, but it does not last as long as the other materials. Fiberglass is more durable than foam, but it is also more expensive. Lead is the heaviest and most expensive option, but it is also the most effective at reducing noise.
