This is a real problem as Folks who only take there boat out for a ride ounce a month and let the Engeine sit without running it are the ones who indeed have a lot of problems with their Engines. More so if it is a Boat that sits in the Marina surrounded by all that damp air.

One person said it was not a good thing to do to Indirect Injection Diesel Engines that it could cause damage if ignited.
