Re: Simple (?) bilge pump question
In the Freestyle Jetski community, we use 5200 to attach dual bilge pumps in the bottom of the bilges all the time.
these ski's take more of a pounding (including inverted landings) than a boat would ever take, so I would have no hesitation attaching the pump this way.
Clean the area with acetone, then use some 60 grit sandpaper to scuff up the area, and once attached, allow the pump to cure for the recommended amount of time before hooking up the hoses and using the vessel.
