Outboard Insulation Replacement
 

I have a 1989 200 HP Johnson. It is pretty loud because the person who owned it before me removed the insulation as it was deteriorating and falling onto the engine. Any suggestions on how to replace since I am sure it will make a big difference in the amount of noise.

i have one of my 225's someone has replaced it in i'll try to get pics of the material

That would be great.

A lot of the boating retailers sell that insulation by the sheet. I forget if it's self adhesive or you use a spray on adhesive. Either way, it shouldn't be too difficult a job.

There is also this stuff you can paint on that is supposed to work well, but it ain't cheap. I will have to dig up the name as I forget, but I know West Marine had it.

Can the AC insulation sheet at Home Depot work? Check in the insulation isle it's laminated on both sides with a aluminum like material. Its widely used in the AC insulation industry.
Different thickness to choose from.
I am planning on using this on mine also. I will use polyester resin as the glue to secure it in place.
If any one thinks this is a bad idea please let me know and I will not go this route, this just a thought for now.

Wouldn't the insulation inside an engine compartment need to be flame-proof?...:head: ...I would think an engine mfgrs ' LIABILITY would be hangin' out about 3 miles if they used a flammable material

Overtons, Boaters World, West all have replacement kits...

Flame proof ?
I am not sure if you have flames under the Cowling having flame proof matters you will go Kubul any way :)

AC stuff will not work, it is a filter not a insulator

What about this stuff:
