    Freestyle 2015 DVX build

    I appologize to anyone who watces this video, but I made it so that I remember how to do these in the spring. lol Watch at your own risk as there are a ton of flips cut back to back. We had a ton of fun that day riding in Rochester, NY with Jay and Chappy. We didnt roll video the whole day...

    What are pistons trying to tell me

    Just remember if your gauge is reading 125, it may be your gauge. mine reads 135 at 180 confirmed. A gauge is a standard to test to, a reference point. If you had checked it last year and it was 150 and now its 125 you would have an argument for a rebuild. dont just spend money based on the...

    Big bore + 155 mag pump = what prop?

    If its going in a SJ based ski you will require a different driveshaft unless you dont mind 5/8" worth of spline engagement. Dont forget the Jetmaniac post about this a year or so ago with photos of the different lengths

    Driveshaft Spline

    If you have the shaft out of the pump throw it in some V blocks, put a dial indicator on it and see how bent it is to tell shaft run out. You can also do in a lathe. All that power your making may have bent the shaft causing some wobble and wear. If you have DS wear, you may have internal...

    JETTLabs Budget Pitch Gauge Set

    Wow very cool Ashby. I didnt see you were making these. I made some overhead transparency copies at work years ago and they work great. I have been using them for about 4 years with great success. I also have the Watcon ones, they both work the same to me. Super idea, and the fact that you...

    Big bore + 155 mag pump = what prop?

    I would say thats a decent starting spot at 7/10 No matter what all props are custom made. It just depends what someone has guessed at for inventory Skat only makes to order. You would really need more details on your motor, pipe, electronics, ride style, etc. But with a surf hull the...

    What Impeller tool do I need?

    FYI, to keep everyone on the same page JetManiac, Fast Elements, and H20 are all the same heavy duty tool. If you ask for it. Thick wall and bullet proof.

    External Fuel Pumps

    The single pump that feeds a dual carb motor requires a 5/16" line from the tank to the pump. One side note is that if you have a single pulse case and dont want to drill for a second fitting, this is a great solution.

    External Fuel Pumps

    Ed is one of the guys that always recomends the separate FP. If you are looking at the throry talk to him, if not you can look up the fuel of the 46's pumps and the remote pump and see that the remote pumps more fuel. Pressure should not shcnage at as all the restrictor is the same. I...

    Cooling line on off valves

    The ones BK mentioned at the bottom i use. Have them at work. I have quick connects and valves everywhere. Have for years. Secret is to tie them from flopping around. You want handwarmers, click. You want to stop the flow to pipe, click. Want to regulate the flow to the motor or pipe for diff...

    Niagara Jetski Album 2015 -Brian's Proformance machine. What's under YOUR hood?

    7' was the reported seiche. Looked pretty close at the docks considering the 6' poles above the docks were almost under water. Docks are abpout 2' tall so I would guess 6-7' for sure.

    Cooling line on off valves

    agreed, but if youre talking about surf and a stand up how would you open the hood to flip the valve. Tough to do in tight surf conditions, youre better off to save the ski and un hydrolock the motor than to sink it and try and save it. Especially in fresh water. IMO. Been there. Now for...

    H2o Designs Torrent Pump

    Okay so were on the same page talking to the same people. That is a huge deal. You have to pick a guy, or crew and stick to the plan. SV-1 with TNT will be great, next change is the 701 :) 144 solas w/9/15 to 148 whould be a 7/12 cut back, H20 goes with 5mm not 3mm for tighter low end hit...

    H2o Designs Torrent Pump

    Some of the testing we did years ago on Torrents we did on 701's. 6/12-7/12 is not out of the question and sounds close. Surf, weight of hull/rider, ride style, pipe, nozzle, pump cone size, head, compression, ignition, carbs, reeds, etc all play into it. Also are you shimming prop, or...

    Other Amsoil Dominator vs Klotz R50

    One thing i have noticed is that data, no matter where its from can be incompllete, flawed, or down right incorrect. That is the reason forums took off. its for all of us to get together and hopefully say in a non boased environment what works best for us. Good luck, skis, oils, motors, hell...
