    Question on pump shoe!

    So took the ski out today and still no good numbers! first thing i did when I got home was look under the ski and the pump shoe and noticed that the 4200 fast cure appeared to have seperated from the hull (could see a little seperation) so I broke out the torque wrench and sure enough the bolts turned a full turn before they hit 12 lbs!! also before re torqing the bolts I put a straight edge on the bottom of the hull and was measuring about .061 on the front and about .060 on the rear (close but still cant find my filler gauges after the move) so my question is do I need to re seal the pump or is re torqing the bolts enough? Is it possible that the pump was pulling down on top speed and then re setting itself back against the hull when I pull it off the water? thanks guys.

    Sounds like it. I would pull it off adn reseal it, make sure the hull surface is really clean when you do reseal it. Use a acetone oe slcohol based cleaner to clean the matind surfaces first.

    I see by your mods that you are using the ppk...did you sand down the ppk to gain clearance...lot of speed lost here if shoe hanging down

    i found that is easy to remove and start again replace you pump shoe brackets while you are at it and use red locktite on bolts. use a bunch of plastic bags from grocery(freebies) to wipe down (makes it smooth)occasionally dipping in acetone the 4200 or 5200 as long as it is fast cure take the extra time to prep acetone lots of rags and blue tape everything that is not getting 42 or 5200 torgue 15lbs every few minute for 5 hrs. also it was alot easier without the pump in. if you take the pump out you might as well replace the driveshaft hose witha heavy duty hose(driveshaft cover) the pic is with the pump in.

    I did sand down the PPK but I DID NOT torque it more than once.. My bad and i only torqued it to 12 lbs. Why should I replace the brackets?? I really dont want to have to pull them off again (what a pain in the ass) also I read a tread where they lifted the ski by the pump (with a floor jack and 2X4) should I do this while torqing it? thanks guys Im going to get this damn thing above 70 if it kills me!

    ok r33 check this out...I was at 67.7 w/1200 grate and it felt like the nose of my ski was down at spees,the 1200 grate is fabulous for hook up and safety when you chop throtle, BUT i wanted speed and safety...so i took off the 1200 grate and started cutting and grinding, i did not thin too much just kinda blended things and cut off the ears and milled top front pad.....but here is what happened..i went to 69.0 instantly !!!! (I have purchased the "package" but have not installed yet)
