    Pulse signal strength relies on compression. Low compression is going to be a weak signal.

    Sorry for the extremely late response, but I finally got this ski out today.

    Not positive on the twins, but domestic triples have an adjustment for the oil pump. There's an indicator mark on the body and a dash stamped onto the actuator lever. Those 2 need to be aligned.

    I don't see anything out of the ordinary. I don't know why you'd be getting water coming back towards the ski rather than going out the nozzle? That seems weird.

    I think you're a bit confused.

    Hot Seat never made domes and a single piece head cover for a 780. That's the domestic engines.
