I've had water shooting out and dislodgeing the plastic cover just below the water inlet on the lower part of the trunk. I replaced the plastic cover and the water pressure just dislodged it again. Is this expensive to fix? Is it an exhaust gasket leak? Also, I've bought a new trim/tilt pump with the 2 lines but from a newer model twin ram motor. Lines seem to fit etc.. will this cause problems with the trim or hydraulics? Thanks heaps, as I'm new to this forum & recently converted to outboard ski boats, as I grew up with and am used to inboards.
