96 Speedster, I was going WOT for about 3 minutes then went back to idle and noticed weird noise from starboard engine. Let the boat sit while grilled out food and then got in it, the sound still there and went for a test, boat goes without any problems no power loss at all but the sound is still there. The best way to describe the sound is: metallic sound when the engine is running on land, which both engines have it on land. When i lower boat in water one of them disappears while the starboard continues to make it in the water. I'm leaning towards pump, but wanted to get other ideas of what to check.
