    That was my first mod once I started ocean riding. All it takes is a failed hose or clamp to sink you. Bilge pump is a no brainer to me and a must have. The kit sold is awesome and that included switch is perfect.

    Anybody have photos of pump placement for a 2015+ vx/vxr. This might be a good off season mod for me. Not that I ride ocean, but solo riding the Great Lakes can be pretty close.

    Whale Supersub SS1212 bilge pump installed in Yamaha GP1800 Waverunner

    GP1800 has the same hull as your VXR.

    I wanted a bilge pump that could really move water. So 1000gph rated or higher. If I ever really need the bilge pump, I want that water coming out fast.

    A bigger pump pump does not use much more battery power than a smaller pump. Once the unwanted water is moved out the big pump shuts off sooner while a smaller pump would still be running.

    If there is water coming in faster than the pump can move it out, the bigger bilge pump still buys me more time to get to shore rather than having the engine stall due to too much water inside the hull.

    While I can’t think of any real downside to a larger pump, the 500gph will keep up with quite a bit of water. It should take care of most leaks or hose failures. Hull breaches are another story...

    Depends on which hose fails. The main water feed from the jet pump can supply a lot of water, at pressure, when the engine is running.

    Failures of the seal where the driveshaft exits the hull can also flow water quickly into the hull.

    We do not get to choose which leak, from what cause, happens, nor when or where. The bilge pump is there to alert us to the problem, and buy time to either get the problem solved or get to shore. The bigger capacity the bilge pump, the more time it buys, especially when the water is coming in quickly.

    The big hassle with a bilge pump is installing it and wiring it in, not buying it. So buy the best bilge pump you can.

    Even if the bilge pump is never actually needed to save the ski, it is still worth it. It provides confidence that water in the bilge is much less likely to sink the machine.
