Hey, just joined this forum and purchased a 1995 Spi last month as a summer project. I took it for a test ride and it went about 40 mph just fine, with seemingly no issues, other than a battery that needed to be charged before every use. I had the ski sitting for about 2 weeks while I was giving it a good clean, and in bottom of the hull I found a small (about 1mm) diameter hose that had come off. I did some searching, and I think it had come off of part of the carburetor on the rear side. I replaced it with a small rubber hose, which in hindsight may have had a slightly smaller interior diameter. Today, I took it to the lake for a proper test drive, and it started right up after I put in. About 50 feet off the dock, I realized I had left the fuel selector to OFF (yes I know this was very dumb) and the ski stopped running, obviously due to the lack of fuel. I switched it to the RES position (didn't have much fuel in there) and when I tried to start it, the battery needed to be jumped. I was able to start the ski again by jumping with a boat battery properly, however I was not able to go any faster than about 5 mph on full throttle, and the engine nearly stalled out. I went straight back to the dock to avoid any more potential damage. I am planning on getting a new battery, and will try to run it with that, but I'm not sure if that's the real issue. From what I can tell it looks like a fuel issue. This ski has had most of the fuel lines swapped from the gray ones, and the only things that I think would have changed from when I test drove it would be the small hose and the battery. Where should I start? Thanks so much for any help. I attached a picture of the hose I replaced(not sure if that is the exact 580 engine). Pretty sure this is an oil line.
