Hello, thanks for the add to the forum. I have an unusual request. Our local lake has a 25hp limit, unfortunately. We are currently forced to use the 1988 and 1989 Yamaha Waverunners, these being the only PWC's ever produced with a 25hp rating. As you can imagine parts are getting difficult to find and to be honest I'm tired of wrenching on them. When Sea-Doo introduced the Spark with a base model HP rating of 60 this is the nearest rating to 25hp since the early 90's. Is there a tuner out there or a "smart key" that can detune a Spark to 25hp? I grew up on this lake, we have a pontoon docked at the marina, and we enjoy the lake very much. The kids love playing on the Waverunners but I'm hoping there is a way to detune the Spark to be approved for use on the lake and get away from the old Waverunners. Thank you in advance.
