well actually Dave... it is not, it weighs about 5500#. Jeff and I just ended a "dock bar" night early with a holed piston on the way over (arrow points to the front, I double checked) and that is a no shi**er! Limped it back on 7 cyls smoking like a 2 stroke!!!! Too much boost,not enough fuel,too much timing. I am an amateur marine tuner and it shows, I know my boundries. Oh well, here comes the 540.
Shane, it wont idle below 8mph, I may have to install a hydraulic clam puller.:tongue:
Did you check the pressure reference line going to the regulator?
