Well.. Picked up a fresh Dominator pump today from Jack McClure himself. I feel confident it is good to go, and he left no question unanswered about install, service or operation.
Let me know a few things I didn't know I should do, like dunking the jet twice at the launch before startup to warsh the dirt and sand that collects in the pump after dragging it through the desert..
I might fab me up a vinyl diaper from excess upholstery fabric to run bunk to bunk to cover the pump intake when trailering, idk, maybe just paranoid or still in shock from paying the money to have it rebuilt right.
However, I'm sure I will notice a difference in how the boat runs with a good, tight pump.
