    The driveshaft on the GPRXP electrically connects the pump to the engine. Just like a seadoo. You will see more sst SD driveshafts in boats with rust than the rubber coupler Yami cousins, due to this.

    2strk setup shouldn't be an issue, or just find a way to use that coupler.

    Mark, after thinking about it some more, the SD pump, engine and plate are all connected electrically. . . through the coolant. I remember being shocked by a battery for the first time standing next to BDNJ's ski in salt water. I say put the anode on the pump and plate, and wire the 2 together. The anodes will do there job

    I am working on an adaptor that uses the yammi coupler.

    Isolation is how the marine shops do it. That's what I'm following.

    Does anyone have any pictures of all the salt water preparation that is done to these conversions? I would like to see different options.

    I don't ride in true salt water, however sometimes our riding areas will get brackish with certain tides.

    There are a lot of GPRXP (and a few GPR/SHO) conversions down here in Miami and most of them ride in salt 99% of the time. Too bad we don't have the opportunity to learn about their builds much less have the feedback from them on this issue.

    how about the anode they use on the yami jet boat? mounts to the outlet nozzle, where the revers bucket would go on anXLT. See part #50 in the pic, there is also one that mounts in the intake grate
