"Looking for some help with my 1990 VP 740A cooling system. I just (last week)replaced my risers and manifolds, thermostat and impeller. When I'm at idle the temp is fine but when I get up on plane then steam is visable coming out of the thru hull exhaust. What is causing this? I haven't checked the oil cooler out yet but I'm thinging that I'm not getting enough water and the water pump might be sucking air with the water when I'm on plane hence the steam. Please help!"
