Going to the Xlerator from JBP
« on: July 30, 2020, 08:57:16 PM »
Good evening have a few questions....well i pulled the trigger on getting the new pump...ive been wanting to do this since last year....right now with a tired jacuzzi wj with a A impeller im running right at 65 with a olds....my hull is a 18ft Mantra light/medium layup its a splash of a sleekcraft sportster....im going to add the diverter as well but what are the benefits of the droop with it? Im thinking if i get it done might as well add it...i currently have no issues cavitation or proposing its reliable...the reason im getting this done cause ive noticed ive been running a higher rpm to get the same speed and do not want to wear the engine out...by no means am i trying to break speed records or anything...engine is a 455 bored 40 over with a cam and stroked with big valve c heads about 100 hours on it

I learned that all boats are different and like different things. Will the droop work for you? Possibly! Will it start proposing like a maniac? Maybe!  Lol
Point being, and this is only my silly opinion, get the pump done(which is way exciting!) and see what it does and how it feels. THEN start tinkering with it if you want.

So are you just getting new stock internals in the pump or upgraded?

I agree with this. I've never tried a droop, but I've read multiple times about others experience plus some guys that own well respected shops have said all boats are different. Weight, bottom, horsepower, jet build are all factors. Another thing that has been repeated is 1 change at a time.
Tom and Josh at JBP have always been very helpful. Definitely give them a call.  Place diverter is also a good place to call.
There is also different drops of the droop.

Well, there you go. Can't hurt to try it. Hopefully, you'll notice a big difference. When do you plan on getting it done?

So he is not using your current pump, right? So when you get it, it should be just a remove and replace (I was going to say a simple swap, but I know nothing is ever really simple)

I was thinking how you said you noticed your RPM's going up. That usually is a sign of a leaking pump, wear ring worn. Like I said, hopefully you'll notice a big difference.

Awesome! if your worried about a full droop you can always ask tom about the HPH from place diverter.  it has only 3.5* up where the droop has 8.5* up angle
