I have a 1998 sea ray 190 bowrlder with a 5.0L mercrusier engine rebuilt in 2009. Pulled it out of winter storage and launched it. New gas in tank and new water separator filter installed. Started right up. All pressures good. Reved the engine out of gear, ran well. Placed in gear and gave it full throttle. Could not get above 2500 rpm and engine sounded like it was not getting any fuel. Backed off on throttle and idled for about 10 minutes. Engine temp came up to 170. Gave it full throttle. Higher rpms this time, then some surging and finally reached higher rpm to place boat on plane. Ran boat for about 60 minutes...never missed a beat. WOT was 4200 rpm and 46 MPH. Slowed down to idle speed and gave it the gas. Came right up on plane and ran well.
The following day went through the same routine and had same results, no rpm or output until reaching 170 temp. Then a surging and then good performance. Question: what is going on. This has not been a problem until this year. Originally thought of water in gas that is why I changed the water separator filter. Any insight anyone can provide would be great.
Thanks,
