Started the boat for the first time since winterizing. When winterized, I had the impeller replaced. When I started her up (on the muffs) the pee stream began immediately. With the old impeller, the boat would have to warm up for a few minutes before the pee stream began and would be weak. I dunno if I should be happy that the pee stream began so quickly and strongly, or alarmed that it did not have to warmup. Ambient air temperature was about 55 degrees.
