The first pump died after 15 seasons. It sounded like a jack-hammer but was a reliable crew member on our boat, sort of like Relic on The Beachcombers. Part of my bedtime ritual was turning the breaker off so as not to be awoken but sporadic bursts of pump.
This pump was made in the USA in 1999 and judging by the date, I’d say it was the original freshwater pump. It started weeping at the end of last (2014) season and I ignored it. At the end of this season, shortly after finishing out trip to the 1000 Islands, it quit (almost exactly like the fridge did last year). Upon inspection the inner sealed-bearing failed and flooded the electric motor. Rust-brown water trickled out of the motor case, it was done.
