A spare impeller can save the day Raw water cooling pump impellers can be damaged quickly by running a boat without water or through silty, sandy water. Once damaged, cooling water flow is reduced and the chances of the engine overheating increased. Having a fresh impeller onboard can restore function and keep you on the water longer. To ensure the proper fit and function, Sierra engineer replacement parts to meet or exceed manufacturers specifications. Each impeller matches OEM specifications for the assurance of fit and function. Boaters and technicians can be confident that function will be restored to manufacturer specifications. Having a spare aboard can recover what may have been a lost afternoon.
