I have a 2000 GW 306 with the factory installed freshwater pump that feeds the sink in my head, the bait station sink and the transom shower. It works fine, but really doesnt have much pressure or high flow rate, which is fine for those applications. I would however like to replace it with a pump similar to my saltwater washdown pump, a Pro Blaster II Ultimate (60psi cutoff and 5GPM). Reason being, is I plan to add a second hose outlet that would be for FRESHWATER washdown capabilities so my "crew" can start washing rods/reels, stainless steel etc on the ride back in after a day out on the water. That said, if I install a pump of that size, will it end up blowing fittings/hoses off on the existing system (sinks and transom shower)?
