Vessel Info: Looking to purchase a 3100 Open
Live in SW Florida
Both of the impellers on my 2000, 3100 Open , have failed. Within days. Did not ground. What on earth could have caused this?
Could it be a failure in my flush out system? Water draining from the raw water intakes when I put the boat on the lift? I never run the engine dry.

Impellers wear out. When was the last time they were replaced? Cummins, for example, recommends replacing the impellers every 500 hours or every year.

They're made out of rubber, at best, they only last 3 years or so.

Impeller are a wearable item and should be changed regularly. I keep a spare set on the boat at all times
Since both engines usually are run about the same I always figure that if something goes bad on one the other is not far behind. I always buy 2 of everything and figure I will be using the other one fairly quickly.

by using the dish washing soap you not only lube the impellers but you can see the soap in the exhaust when started
