Hi all
I have a 89 Johnson 15 hp and noticed when I pull the hood off there is black granular powder all over the engine and compartment. It is the hood insulation degrading and powderizing. (spell Check) I looked on line and the OEM insulation is discontinued. I really don't want that stuff in the carb as we all know there is no air filter. so the question is.
1) does anyone use a substitute material to replace it ? maybe some of the foil faced insulation for water heaters. and
2) is it something I really need, does it provide heat and noise insulation or just noise. and how much louder do you think it would be without it.
Thanks to all
