    MSX110 Max Speed 7mph

    My 2004 MSX110 would not go past 7mph after I had restarted during a ride when it was running fine. A friend said it may be a fouled plug. So after 2 weeks of returning to the lake, I replaced the plugs today. It ran great and I thought wow I have solved this problem for $13. I ran for about 10 minutes with no problems. Came back in for a break, went back out after about 1 hour. The same problem happened again, would not go past 7mph, so most likely the plugs were not the culprit and changing them did not help. Anyone have any suggestions? I did see something about a IFB system part number is 2410507 where the ski would not rev past 3400 rpm. Thanks.

    Replace the TPS there is a thread out there tells where to get one from a auto parts store I checked Napa there was a little High but they where around $30.00 Someone had a Cross over part number.

    I have a MSX 140 that did that and it was the TPS

    MSX 110 is a turbo 4 stroke and doesnt have a TPS. Knowing what RPMS its running at is very helpful though

    Take time to check the pump, you would be surprized how a piece of rope or crap can cause problems, K447 picked up a plastic bottle cap once.

    Thanks for the replies. It will be a few weeks before I am able to check the exact RPMs.

    Finally got back to take the ski out for the winter. It ran great and this problem was gone. Any ideas on what it could be? I get the feeling it will happen again next season.

    I was out last weekend as well and 7mph was around 3400 rpm for me. Perhaps the reverse switch is corroded or out of adjustment. Your SIFB (System interface box) could also be acting up (less likely, but...).
