I have a 2006 Moomba XLV with the assault 325 motor. When I start the boat and shift into forward gear it shifts smoothly and moves forward. If I return the throttle back to neutral and then attempt to shift into forward gear it will not engage and the rooms will not increase. If I turn the ignition off and then restart it it will shift into forward gear until the next time I put it in neutral again. I have been told that it is an issue in the perfect pass system (original non gps system) and that I need to get it serviced. Has anyone ran across this and know the fix? I am thinking about going ahead and just upgrading to the stargazer gps perfect pass if the problem is in the PP system. Any help would be appreciated thanks!
