    Hello JY, If both the 85 mm and the 87 mm have the suctions tube in place or both removed. I found it to be about 50 to 60 rpm's

    Hello Tanny, If you look inside the nozzle on the left you will see a tube sticking inside about 1/4 of the way in at a angle, That is the tube for the bilge pump it works of suction.

    what if you just cut it off flush with the nozzle wall?? will you still gain rpm and will it still work if you get water in your hull after cutting it off?

    Jeff,
    it won't work if you take it out of the middle of the nozzle. In fact, it could start pushing water into the hull. Either leave it as is, and use it for bilge, or remove and plug it.

    Hello Jeff, Mark is correct if you take the tube out or cut it inside the nozzle you need to take the hose out and put a cap and clamp over the suction fitting to the hull.
