Re: 2007 Mercury 25 horse Jet Drive
what is the dealer going to do?
the jet pump will run sand from the intake out the discharge and other than some wear should not hurt anything. (check with
www.outboardjets.com)
The sand going from the water pump into the engine is not good on the water pump, but if ran in fresh clean water after the incident should flush most all sand from the head and pee tube.
If it has a T stat, pull it and see if any sand is in the area, clean with air the pee hose and back flush the engine. If any sign of restricted water flow from the pee hole appears, replace the water pump impeller and housing if it shows signs of wear.
