Your not going to find a lot of people here that have them, but I have quite a few clients overseas that run them and they all love them. It's nearly impossible to cavitate with this pump and hook up and acceleration are unbeatable.

I use this same pump, only the Yamaha version on my turbo FZR. It's a very good pump.

i know you have to have alot of power to run it..custom props ect..very few here are that hardcore ..to spend 3500 on a pump..even though they are the heart of our skis it is just a ton of $$ i have ask the same question..and got no real feed back

They're actually $2888, but I get your point. It's still a lot of money

There's a huge selection of props. Name your pitch and I get it done for you. No problem!

Traditionally this has held true with the Skat Magnum pumps, but this one acts differently. Most people report a speed gain.
In fact, Dean Charrier was using a seadoo pump conversion on his VXR and tried the Rotax Racing Yamaha pump and gained nearly 4 mph. Info in this thread http://www.greenhulk.net/forums/show...-Pro-VXR-build

This is the pump I'm using. It's a direct bolt in replacement for the OEM Yamaha pumps
