"Hello! We have a 23' Bayl
"Hello! We have a 23' Bayliner with a mercruiser engine which I think is 5.7L. 1998
We have a recurring, intermittent problem. After about 20 minutes running on plane at about 37000rpms the boat suddenly loses power, back fires and then there is a smell of gas. Temp is at 175 and oil gauge OK. If we wait a while we can get the boat to start again but as soon as we put any pressure on to get up on plane she backfires and loses power again. The mechanic serviced the engine - changed the impeller and thermostat, checked raw water flow, and checked the timing. When we complained it wasn't fixed he changed the fuel filters and found a small piece of loose silicone in the fuel line near the check valve. He figured taking this out would solve the problem - it hasn't! Any suggestions as to what he should do next - he doesn't know and we are non-mechanical so no help! Thanks"
