Hi guys.....I'm new to this forum but not so new in the Seadoo industry. Been a fan and a user for more than 7 years and never encountered a problem like this.
Got this water flooded gtx 787 rfi from a guy, put new crank, new top end, new seals...everything. all cleaned and as it should be.
Started on the hose a couple days ago and runs mint. Chucked it in the water and after about 10 minutes of great and proper running. bogged down, wouldn't accelerate what so ever and eventually died because of the low idle. Removed the sparkplugs and number 1 was fouled, with a lot of unburnt fuel on it. The other was good and sparking right. Put a set of new ones and the same story ( 10 mins and after died)
Got home, checked fuel px ( 56 59 psi), compression 155psi both cylinders, no water leaks, NO MIDDLE SEALS LEAK, no water contamination , charging properly 13.7 volts, reset the tps and no fault found while scanned!
Swapped the injectors around and got the nbr 2 sparkplug fouled this time so definitely the injectors.
Got a pair of SH ones and got the jetski running for about 35 -40 mins this time ,than BANG ---- nbr 2 fouled again, jetski dies, barely accelerates around 2000 rpm...!
I'm running out of ideas!!!!!! SO PLEASE HELP.
What i'm thinking: - the sh injectors are damaged and leak to much fuel under load and when the ski is warmed up
- the coil pack is damaged ( pretty rare)
- there is something that damages my injectors ? ecu / mpem
I'm sure are some experts around here or people who encountered the same issue
