As others have said, if she smells diesel there is diesel in the boat--where it shouldn't be. If you clean down the engine
space and tank and make sure there are no leaks
(a steam genny is probably the ideal way to do this) and there's still a smell, it can come from diesel that has soaked into unfinished plywood
or other materials. It can be a b|tch to get out of them but that's necessary to get rid of the smell. Get rid of the mislocated fuel
, and the smell will be gone.
That can mean detergent cleaning
, solvent cleaning
, painting and sealing with epoxy
or urethane paint
, and if you run an ozone generator
on the heavy side for a while, that will also help burn any diesel fumes out of the boat. (There are pros and cons to ozone generators, but they do kill smells.)
You might also look into a couple of the Nicro solar
vents for the boat, if you keep it constantly vented with fresh air, good things happen.
