    I don't see any reason to believe that won't be adequate. What pressure do you plan to set the AFPR? Factory is in the 40-50 range correct?

    I can understand that. Especially when running one fuel pump for two engines. What are the specs of that fuel pump? A twin engine 160hp MR1 powered boat burns I believe just under 100 LPH at wide...

    Good progress. Not familiar with the fuel setup on XR1800 vs my LS2000 but I would think it would be most effective to place the fuel pressure regulator on the forward wall were the fuel line come...

    Backstory - Ski came in down on power. Found low compression on PTO cylinder. It had 0.5...

    Late to the party here but thats crazy. I rebuild carbs for ~$150 per carb (genuine kits and needles/seats included) and charge $50 an hour. I would probably only charge 2hrs labor on the bendix and...

    How familiar are you with 2 strokes? Cause it almost sounds like you are just not used to the 2 stroke power band. On the 1100/1200 NPV motors anything between ~3500-5000 RPM is useless as it will...

    I'd say that wouldn't be possible. Completely different engines/timing curves to benefit from the power valves.

    If it is bogging out of the water it will definitely bog in the water. The air intake not being on can cause a lean bog do to the change in air flow/signal through the carb throats.

    I believe it has as bit to do with both cylinder temps and air flow through the air box into each carb.

    One test for checking for a air leak is to completely close your throttle blades (turn out idle adjustment until not touching) and then see if it will start up and idle. As long as the carbs aren't...

    I think you are over complicating the situation. Especially when talking about a stock ski.

    At the end of the day, a stock ski doesn't/shouldn't need this. And if it does then there are other...
