https://cvws.icloud-content.com/B/A...dDocs&p=42&s=X8HOVjN_dqiMHxUvbZEBxD4XkGs&cd=iI have a 10 foot Zodiac driven by a 10 hp Yamaha short shaft. The water pump works beautifully until the boat goes on plane. When fully on plane the telltale stops showing water and will not flow water until I come off plane. Once off plane the water flow is very hot for a few seconds indicating that no water was moving through the engine. It quickly cools thereafter. Any ideas on why this might be? The intakes seem fully submerged on the outboard. I appreciate any help as it has cost me a few impellers whenever a new driver is in charge.
