Okay here goes one more time with this thing. I have a 1990 Sea Ray Mercruiser Bravo 1 I blew the motor and bought a complete 1999 7.4L MPI and sliped it in place of the old. Difference between the two old 7.4L carb new 7.4L MPI serpentine belt. I used all the 99 stuff except the old style actuator. now what it does; the out drive takes off to the right hard or Left turn Clyde! It would be great if I were in nascar. I have tried almost everything. bought new (old style actuator) ajusted the actuator, tested the pressure (1200-1300). My questionnow though has to do with the hose's the 90 to the 99 the fittings were different we went with the 99 and had different ends put on. Does anyone know if the hose size's were differnt between those two? if they were would that make the difference and force the outdrive to one side? any help would be great. Thanks
