Part 2: Is repairing plastic Seadoo jet pump possible? In my opinion, yes.
So here's the juicy bits I am sure you are here for:
- Grab yourself the Hobby welder for $9 (or the 80 watt version, but may get too hot, making the plastic brittle)
- Grab a package of plastic welding rods. I got the mixed bag, but if you can, just get ABS (white)
- Pull your pump, drain the fluid, pull the cone and then pull the impeller. I picked up a Seadoo impeller tool for $8.95 from Bay Area Powersports. Have purchased numerous parts from them, including aftermarket MPEM for GTi and they've been good...
- Use a well ventilated area like garage or porch area, because the fumes from the plastic are nasty/toxic, and always seem to drift towards your face.
- Small pen style or LED flashlight.
- If you have access to a dremel or die grinder with long shaft, it makes cleaning up the veins after melting easier.
- Give yourself time, as this lower wattage is a slow process, but as stated, won't overheat the plastic and make it brittle.
OK... So here we go:
What you should end up with is a nice, solid plastic area, perhaps a bit thicker than the stock veins. It will probably be rough, but you can come back and smooth that with the flat edge of the hot iron. If like me, you have multiple broken/cracked veins, it should probably take 2-3 hours, but should end up something like this.
My initial runs were not great performance wise, as this ski sat through the winter and had old fuel. I will probably pick up some carb rebuild kits to be sure. But once I got her warmed up, I was able to get it up around 6400-6600RPM for a long stretch. I also did some zig zagging and jumped some boat wake in an attempt to rough up the jet pump, and put some stress on things. I did not take it to the inlet to do some much desired surf jumping yet, as I gotta get the carbs rebuilt and tuned, but it was a pretty solid couple of runs.
However, I'm happy to report that nothing broke loose, and the repairs I did seem to be holding strong.
Obviously time will tell how well these hold up, but I wanted to share my experiences with others, as I have seen a number of people with this same or very similar issue with the plastic pumps. I will definitely post back positive or negative as the season rolls on.
I probably spent about $25 on the materials, the Hobby burning tool and other things needed. Yep... $25!
I apologize again for the wordiness... I'm just the over-descriptive type... but I hope some of you found this information helpful and gives you the confidence to at least try to repair something like this and save yourself some $$. (or spend on other goodies)
I will be posting some of my other "MacGyver" additions/fixes to the skis, like repairing the GTi sea that was in pieces along the edge, (saving myself another $250) as well as making custom 3-tone seat covers for both my skis with this killer carbon-fiber marine vinyl I bought online that was incredibly inexpensive, and enough for me to make another 2-3 seats. I'll even do a post about painting both of them with a temporary spray booth I built in my garage, along with mistakes made there.
Stay tuned for my other posts, and thanks again to all who have posted helpful How-To's or comments to other postings!
