We bought a used 2003 Yamaha FX140 with 81 hours and it seems to be slow for a 140hp waverunner. We had a VX110 and it was alot faster than this one. The motor seems to rev up well but it feels to me like there is a slow response from the jet drive, I can't explain it well but the motor revs up quickly and the jet drive seems to take a long time to respond. The jetski will eventually get up to about 40-43mph and seems to top out there, I had expected more like 50-55mph. The motor also seems to have a slightly rough idle (not sure if this is a prob tho) but is very smooth when revving up to speed.
Since I'm a newbie to working on waverunners I was wondering if someone could give me some basic things to check in the jet drive before I blindly just go haul this thing down to my local dealer for their diagnosis? Thanks in advance for any tips or ideas.
