Recently my boat began to exhibit the following symptoms: <br />Cavitates during acceleration out of the hole <br />Cavitates while on plane in flat water with frequent jumps in the RPM as if it is ingesting air. <br />These symptoms have gotten steadily worse. <br />I think that this all began after the engine backfired while starting it (in the water). Is there an exhaust gasket that could be blown (leaking) exhaust into the impeller area? <br />Thanks for any help.
