Isn't it the suction of the intake that allows a jet sprint boat to generate multiple G's in a corner.
Just try putting a pressure/vacuum gauge (like a boost gauge) at the front of the intake foot. I would expect greatest suction to be when booting it from a standstill and greatest positive intake pressure would be when you close the throttle at high speed.
I can't be ar$ed bothereing to try and explain.Out.
To lift the water into the intake and flow it through the jet unit,its gotta suck it.I gonna ask hammys on here,they will know .
Hull design.Done that
Everyone should retire to the dunny and not come out until they have a sensible solution.
Didn't the old 750 hami's have an air bleed which sucked air into the intake, and I would have thought that to change the direction of water flow, especially at speed, to come up into the intake it would have to be sucked up ?
Hacky, The air bleed pipe is just that. It allows air to bleed out of the front top of the unit so water gets in and the unit is primed, when starting. No water comes out this pipe unless you let fall down to the the level of the unit, so it is not under pressure. It does not let air into the unit as most of the time the level of water up the pipe stays the same. Cheers
