Pros/Cons starting PWC without jet pump
Couple of questions:
1) Can I run my engine without the jet pump attached and water supplied only by the flushing adapter?
2) New top end $$$ what is the proper break in period/ procedure?? I'm running Pre-mix.
3) Are the driveshafts the same length for a stock jet pump and a extended jet pump? My driveshaft is stuck in the coupler any suggestions to free it.
Or should I just wait till I get the thing in the water to do this right!
Its been awhile...I just want to hear the thing run!!

Either Remove The Pump And Driveshaft And You Can Run It On The Trailer,or Reinstall The Pump And Wait Till You Get It In The Water,i Hook Up A Hose And Run In The Direction That The Pump Pushes It Through The Motor Without The Pump Or D/s In It,my Pro Is Currently Sitting That Way

1. You can run it without the pump, but make sure you don't have the driveshaft in it either. 2. Use 32:1 for break in. Vary engine speeds, but never go to WOT. I wouldn't even go past 1/8 throttle while on the trailer. Run it for 10 min. and let it cool for 10 min. Run it for 15 min. and let it cool for 15 min. Run it for 20 min. and let it cool completely. I'm not fond of the backflush adapter, so I disconnect the cooling hose from inside the hull and hook up the garden hose to it. Yes, start the engine BEFORE the water and shut off the water BEFORE the engine to prevent water filling your cylinders. Then when you're in the water, vary the engine speeds. Never go WOT or cruise the same RPM for extended peiods of time. 3.The extended pump uses a shaft that is 4" longer than the short pump. 4. You can start the break in process on the trailer, but you will need to put it in the water to finish the break it in. Yes, about 10 hrs or usually 2 tanks of gas and ease in to WOT. Good luck.
