Trayson's 2008 XLV ballast system upgrade

I would caution you on using an Impeller pump <unless I misunderstood> for a Spray head like that. You will need a bleed off valve. If not each time you stop spraying the hose the pressure on the pump will burn up the pump, or blow a line.

I would use an aerator style pump to power the spray nozzle, or just connect it to a through hull and let the weight of the boat in the water force the water up the hose. Won't be as much pressure but works none the less.

The second option wouldn't work. Water would only come out of the hose if you held the end of the hose below the water line of the lake. If you held it up any higher, nothing would come out, the water level in the hose would stay the same as the lake. (The weight of the boat doesn't really matter, only that it does create an air space inside the boat that is below the water level of the lake)

Fair enough, I hadn't thought of that.. I can get a different nozzle for the hose, one that doesn't shut off. I think I saw one at the plumbing store that would work...
