    Default Bowl drilled crooked ???

    I think the bowl was drilled slightly off. This is an older Aggressor conversion for a Jacuzzi YJ. It is similar to an Energizer kit. I noticed it when I swapped this pump from my Ambassador to my Rebel. I could see from the back that the nozzle was rotated slightly counter clockwise. Now that I have added a Place droop with ride plate it is very obvious. I checked it with a degree finder at the machined surface on the top of the jet intake. It reads 0*. I also checked the top of the hand hole cover. Again 0*. I checked the ride plate and it has 3* of tilt to it. My question is, how critical is this on a 60 MPH boat? I can think of two ways to fix it. Slot the holes in the place droop so I can rotate it slightly, Slot the holes in the suction housing so I can rotate the bowl slightly. I think I would prefer to slot the suction housing simply because a YJ suction housing has much less resale value than a place droop. Any thoughts or suggestions?

    Unless the boat pulls real hard to one side, just level the ride plate and you'll probably never know the dfference.

    Thanks Duane. That seems like an easy solution. The boat did not pull prior the the droop.

    That is one of the things I will be checking when back on the water this spring. The droop & plate was a winter project. If it slows down off it comes. Thanks for the concern though.

    Matt I'd say your theory is probably correct, a shot from the side and a couple more pics in general would help, I wouldn't drive it till you figure it out anyhow if it is the bowl ,pull it , send it out we'll fix it for you N/C and send it back no matter how old it is Tom

    Take a good look at the bottom picture. The reverse gate in pretty is line with the bottom of the boat. Which means the pump in pretty much in line with the boat. The problem is with the ride plate. It is way the hell off. This could be a problem with the mounting bracket or the clocking of the web on the bottom of the droop.+

    The Place Droop has a cast rib/brace that facilitates an "add on" ride plate which requires no machining or actual hull attachment , its only attached to the droop and is designed to "butt" very close to the transon, just above "keel" and transom base Tom

    It's hard to get a pic with so much black. The nozzle is pretty much just as crooked as the ride plate. I will get some better pictures today. Maybe I can highlight the bottom edge of the reverse bucket with chalk or something so you can see it better. Before I put the droop and ride plate on the nozzle was crooked enough that you could see it even with the stock nozzle adapter. It is just much more obvious to the eye now with the ride plate. More pics to come.

    Did a little more investigating. I think it is a combination of the intake and the bowl. I could not get a pic of the gauge on the intake but it is 1* out. I checked it both at the intake and at the hand hole. The pics tell the rest of the story. I really don't think it is that big of a problem. This is not a fast boat. I hope to see 65 this year. I think the easy fix is to shim the ride plate level and leave it be. Anyone else have an an opinion?
