I have been a long time snowmobile fanatic and decided to purchase a couple wave runners this spring to help "tide me over" until snow returns. I don't know much about these. I purchased a 1997 Sea Doo GTi and a 1997 Sea Doo GSi.

Do I need to remove the carbs and clean them before running them this summer?

I have read about the pump oil needing to be changed, is this something I should do prior to running them too? (Don't know if it's ever been done). How difficult is it? What oil do you recommend running in there?

What other things do I need to do before I set them in the water?

The GSi has a non-working fuel gauge and I was reading the post on repairing the sending unit by removing and soldering the F1 fuse, so i'm gonna look into that.

Also, the GSi has a pretty large gouge out of the gel coat in the hull, you can see the fiberglass underneath. Will this cause any problems? Do I need to patch it or will it be ok to run like that? The previous owner said it doesn't take on any water.

One last question... what oil do you guys recommend running in these? Should I run Sea Doo oil or do you run any aftermarket oils like Klotz/Amsoil?

Any help/suggestions would be greatly appreciated!!

I would worry more about the fuel lines and carbs than the oil pump. Take the carbs off and clean them with extra attention to the fuel filters (in the carbs). If you notice green build up in the carbs and you have the old gray fuel lines I would also replace the lines. It will take about 20 feet of line and about 20-30 clamps if you don't reuse the factory ones. I would inspect the oil lines from the pump to the manifold to make sure they are not brittle. If they are you can replace them with "weedeater" fuel line from a local lawn mower shop. Dirty carbs causing it to run lean or broken oil injection line cause people to believe the oil pump has failed but that is pretty rare with a mechanical oil pump. As for the oil, in my experience with marine two strokes any TCW-3 oil has to meet standards. I have used Walmart TCW-3 for over 10 years in my outboards and now in my skis with no problems. As for the fuel gauge and fiberglass, I don't have any info. Hope this helps I just went through all of this last week with my 95 xp. Now runs like a scalded dog!
