Every time I take my boat for a spin, I have the problem of cleaning this black residue on the back of my boat. I have twin 450 Cummins on my boat and when starting or running there is no visible black smoke coming from the exhausts.
First I would like to find a way of preventing this from happening. If there is no way of doing this, is there a easy way of removing this residue without harming the gel coat or removing the wax on the fiberglass?
