Ok I have an 87 sea ray seville with a 87 ford 2.3 and an omc cobra drive. The problem I am having is that everytime I get the boat into the water under load and advance throttle to go forward or reverse the engine will stutter and my oil pressure drops to about 10psi and boat dies. If i run the throttle up in idle the oil pressure will jump up to about 60 psi and stay there but as soon as i try to put in gear the pressure will drop, engine stutters and boat dies. it runs fine out of water on a baffle and I am only having this issue under load. Any ideas???
