[QUOTE="CedarRiverScooter, post: 381224, member: 15465"] Got the top loader grate today so just had to try it out (1 screw install). 1/2 way there. Got it to hook up well when going into the chop, but still cavitates going with the chop. Engine is topping out at 5000 RPM, so I think I need the SLT impeller (lower pitch). With the good hookup I can nail the throttle so the mid range carb problem was not relevant. Piston wash says I'm rich so not melting any pistons. I stared at the pump intake for a good 10 minutes & finally decided to try a 4 foot long spoon, made from treated 1x4. It will terminate at the junction of aluminum & ski hull (well before the intake). 1x4 will be on on each side of the center rib (tapered to fit tight) will be about same width as the intake. It will have the granddaddy of exit taper to match the flow of the hull. Hopefully this will direct the air outboard. If I could start over I would plant the jet ski hull deeper & use it's keel as the spoon. It could have been so simple . . . [/QUOTE]
