Let me try to explain what they had to do and what the problem was. The Teleflex shifter and throttle handle unit were manufactured incorrectly in the linkage attachments below the deck. When I looked at the replacement part at the dealer, you really could not tell that the part was much different.
The problem was as follows: We all know that on the basic SeaDoo models, to start the boat, the shifter has to be in neutral. Well, on the incorrect unit you could start the boat with the shifter in Forward and the throttle in any position. That could be dangerous! You could start the boat and it could immediately take off forward! Also, the new unit makes sure that the throttle is all the way back before allowing moving the shifter. The other thing that the new unit does is this: When shifted in Reverse the throttle throw is limited to about 1/4 throttle. So you can't accidentally go full throttle in reverse.
Question; Is needing to have the throttle all the way back before being able to shift a modification to stop the practice of the "submarine move?" I don't know haw to do that, but I am just wondering?
Nothing in the change out is electrical. It is all mechanical in the linkage assembly below the handles.
I can't say enough good things about my dealer, Tim's Ford Powersports in Winchester, TN 931-968-0114, owner Marty Coe. If anyone is close to there and needs sports boat help or pwc help, give him a call.
