I have two 2007 GTXs with 90 and 105 hours. Bought used and put few hours on each. YM (hull number) went 52mph. YK May have gone 52, remember 42mph then 30mph with slipping acceleration. Changed wear ring and impeller to Solas 11/19. (Thanks Joe Z.!)
YK after now only goes 42 mph and on first acceleration popped alarm and code P0326. Knock sensor?
YM was going 52mph then 30mph and suddenly full reverse when accelerating. Turned out top two bolts on the Venturi sheared off! Thrust shot up and over forcing reverse shroud down by itself!
Gonna fix YM by putting YK repaired pump assembly with Solas impeller onto YM. Is this bad idea?
Going to rebuild YM pump since drive shaft impeller factory seal was crimped when mounted (looks like mud inside. Will use Solas 11/19 again.
Both running on marina gas. Should I replace YK knock sensor? Or is it something else?
Is it a bad idea to take YK’s Solas impeller pump and get YM up and running (hopefully 52 again)?
