I just replaced mine....same problem. They don't make it any longer, so my dealer had to check with other dealers to find one. No fix that I know of. I paid like $92 for mine, so get ready.
I just checked it's available from Riva Motorsports, click on "PARTS" top of this page, for $91.00. The other option is to buy a good used one, PM minnetonka4me he's probably got one.
Thanks.....But already got one from another guy on the forum.....I just got myself a new project ski. I aquired a 95 SPX. Its been sitting for at least 5 years. As soon as I finish the motor job on the GTS I will be starting on that. How is your inventory on parts for that and what is it worth in good running condition? Dont want to dump more money than its worth into it. If its going to cost a ton Ill just part it out.
