Good evening,
I have a 1992 Boston Whaler Rage (13.5 ft) that was upgraded several years ago from the 650 to a Yamaha 760. I’m having the carburetors rebuilt and they’re asking if I want to change the jets from the OEM setting (waverunner) to adjust for weight of the boat (which I think is around 800lbs displacement) and two adults (300 lbs for both). So with boat, gas and two people 1150 lbs. Their concern is that the OEM jets could be too lean and damage the motor.
Currently (1.5 needle/seats, 115 Pilot jet, 135 Main Jet, and 115 gram spring for each of the two 44mm carbs).

Any help would be appreciated.
Thank you
