2" pump spacer and five (5) 95mm bolts available?

Why not an XLT1200 hull? Lots of them out there, similar hull to the FX140, and same 66V motor.

You might also post your location, or add it to your profile.

Just saw this pop up and figured I'd weigh-in on VX fuel economy. In our Yamaha SUV MR1 conversions, with the 1052cc MR1 (VX motor), an 18.5 gal FX fuel tank, we see a little over 100 miles at...

After struggling with this same problem for years, I now reverse-assemble the 12F/15F motors. Start with the cylinders and top case half only, and drop-in each piston from the top (rod attached)...

This is a 1999 66V Powervalve motor that came out of a freshwater ski. Very clean. Has one low compression cylinder. Approx. 120 hours on the guage. Selling complete motor and electronics, including...

3/8 DeWalt cordless impact to dissassemble. Will use to reassemble, but just to run the bolts in then hand tighten or torque.

I launch single trailer skis almost exclusively with my golf cart. Plenty of torque in an electric cart to pull a ski out of the water, but you have to be careful to not back the rear wheels over...

Most folks have moved to jetboaters.net. Many more knowledge folks there.

Basically the no wake feature has you put the bucket in neutral, then increases RPMs. Talk to these guys and see if their...

OMG, it's just wrong. That is a VX110 hull and someone put a 2-stroke motor in it. Run away.

-Greg

I go in thinking of two prices: (1) In good running condition with no issues, and (2) everything else. The ski you are looking at is in the #2 category, and if the owner does not want to spend the...

If you are moving the motor mounts for a 66V, you mind as well put in a 4-stroke MR1. See recipes below.

As far as water boxes, I can't really say other than the ski runs 52-53 mph, same as a stock early model VX.

I have had this ski running about six weeks now and have ridden quite a bit. XLT hull...

Might be tough getting an MR1 into that hull, and you will need to move the motor mounts on the XL. My recent XLT/VX build thread is below. Different hull, and setup for a 66v 2-stroke, so the motor...

Bought a 2002 FX140 that sat outside in the sun for a long time and now the speedo/meter is faded beyond use. Part number is F1B-6820A-00-00 and still available from Yamaha, but very expensive...

We ride from Lake Livingston White Rock Creek area up to highway 7. 100 miles each way. You’ll want to ride when the river is lower and no trash in the water (like right now). Know there are no...

Button it all back up, and there you have it.

I am just waiting on a trim cable and cable extensions... should be here tomorrow and I can water test this week.

Used a dremel to fit in the gauge. Also painted the area black to blend in better once the "engine cover" goes back on.

Fuse box mounts to the side, near where the VX harness would expect (and can reach). TPS is not shown, but mounts on the port side.

For the exhaust, I have to shout out to my buddy Kevin who tipped me off to using an XLT/GPR800 exhaust which already has 2 1/2" nipples. The water box to resonator hose from an 800 also fits...

I did not get a photo of me shoe-horning the motor in, but here are some tips:

- remove the handle bars and complete engine cover (make sure to get all the bolts to not damage when you remove)
-...

FX fuel tank pushed all the way to the rear. You can use the XLT hose cut into sections with 2" stainless, and an extra piece of fuel hose in between.

You will want to use an FX tank as it fits in...

Sealing the pump shoe with silicon for anti-cavitation good luck.

The 2010+ VX 24 3/4" driveshaft and mid-shaft and a 2" FX spacer.

Hey folks, if you part FXs and sell on eBay, sell the 2" spacers along with the longer bolts that are unique to FX. They are tough...

Test fitting the MR1 with a mock-up motor. The 66v has the same motor mount locations as the 66v, so no work there. Motor also clears the humps in the inner hull.

Measuring the driveshaft, this...
