    Default need some loading help!!

    well, had a great time over the weekend, my boat ran very hard, no motor issues, but i'm still having hell making it past 700ft without blowing the pump. i watched the intake pressure gauge and at 400ft i had 50psi, and by the time i'm at 700ft its down to 15-20psi i'm running my shoe at keel level, open loader 1/16th above keel, ride plate is straight and set at 4.5 degrees up from keel. i installed a dps inducer , race shaft, and uwr prior to racing last weekend but it made no difference in how the boat loaded on the end of the track no better, no worse. i've changed shoe depth, i've changed ride plate angle, i've changed nozze angle, it just won't stay hooked. i'm leaning towards the droop as the issue, i think it's just createing way to much transom lift and by the time i'm 3/4 down the track, the boat is flying to high and unloads. tried all my divertor settings trying to keep it loaded , but nothing helped. any thoughts?

    Loader seems a bit deep...blocking water, to the shoe, on the big end.

    i've got a semi v blocked loader that hangs 1/8th above keel i'm gonna try next wk while on the lake for 5days before i scrap the droop i wanted to try the other loader again(because i've lowered the shoe to keel recently) and i'm gonna take a dominator oe steering housing with me, take the droop out entirely if the loader doesn't make a change in what's happening.

    Don't be afraid to cut on your loader, they rarely work perfect n every boat. Cut the leading edges back, cut the blocker back and such.

    I'S not scared to cut on it, had to trim off 2inches just to get it above keel to begin with what i am scared of is taking too much off and ruinin a new loader the other loader i've got is a semi v blocker bout 3inches long, and it hangs 1/8th above keel. i'll try it next week and see if intake pressure improves. i'll have the time to do back to back tests, and i'll let yall know the difference.

    Does the loader your running no slow you down sort of fast when you lift? IMO it seems too deep still, 3/16 in to 1/4 in would be your target area for the loader above the keel/shoe. Now keep in mine the V-blockers add lift too, if you wan to run blocker, use a flat type bocker.

    i'm gonna take it up a bit more, i do think its still a tad too low, thanx for the advise. i think i know what was causing my issue now, the aggressor impellor has 3 1/2 blades on it after only 3hrs of run time the other 3 blades are cracked and folded slightly
