I once had a mysterious leak in my SXIPro. My jet ski mechanic suggested I take the battery out before putting it in the water to visually check the shaft seal. With the battery out it didn't leak until I pushed the rear of the ski down so water entered the tray, then I could see water dribbling...

You'll need a multimeter set on the lowest resistance range, you're expecting a value of less than 1 Ohm. First put the probes together and take note of the reading. This reading should be very low, probably just a fraction of an Ohm. It represents the resistance of the test probes as well as...

I wonder if a corroded wire/connection could cause this. Have you measured the earth connection from the battery to the CDI for excessive resistance?

+1 A spark gap tester will help verify the strength of your spark.

I've had two separate ignition problems with my SXIPro. Both intermittent in nature. First, random loss of spark lasting a few seconds up to a few minutes at a time. Completely random, but it didn't happen every time I took it out. A couple times I pressed the start button while still...

The reason I ask is because I've been reading about the problem of motors flooding while being towed behind a boat. http://www.x-h2o.com/threads/67551-Towing-ski-behind-boat One way to prevent this is to put a small ball valve on the coolant line to the manifold but the other day it...

That upside down U shaped water line from the head to the exhaust system, the one with the flush cap on it... Is that the only pathway for water to exit the cylinder block and enter the exhaust on a stock 750?

I'm not familiar with the SX750 but have the SxiPro750. My ski will turn over with the lanyard out or the stop button depressed. You could start by checking the start /stop buttons with a multimeter to see if the stop button is perhaps malfunctioning and so preventing spark. Looks like...

The glue inside that heatshrink is just hot glue. Because this stuff only seems to be available in black, I do it like this... Squeeze clear hot glue onto my solder joint (messy, hot, ouch!) and wait for it to harden. Slide a section of clear heat shrink over the top and warm it with a heat...

Mine does the same thing. Haven't done anything about it yet but have been thinking I could put some kind of silicone between it and the alloy and then stuff the space between the bumper and the pole with paper towel/rags to hold it in place while the glue sets. One day I'll get around to it.

I've always been overly worried about water getting back to the cylinders and crank case via daily evaporation/condensation cycles. So I've been trying out an idea for a few months now. After flushing and running the motor dry a few times I've been ventilating from the flush fitting with a...

Why is Silicone Sealant not used to glue down Bilge Pumps?

In my case it turned out to be a faulty ignition coil. The longer the motor ran the weaker the spark got. I suppose the coil was warming up the longer the motor ran. That's when the fault showed. This particular coil was less than 12 months old. I had previously changed it over while...

Is it also difficult to start after 30 mins?

I also have an Sxi Pro and am following your thread with interest. This is educational for those of us who've never pulled a ski apart. Keep up the good work, and keep the pics coming.
