JT1500 nozzle step
Anyone notice this? The nozzle area after the fixed guide vanes (which is between the pump and the steering nozzle) seems to have a reduction step inside. I'm thinking a smoother transistion might be technically better for flow efficency? Heck maybe these things don't care whether it's there or not. I noticed this while inspecting the impeller and adjusting the steering cable.
Also noticed the first muffler rubber debonded and chafed in the curved fiberglass muffler seating area. Used DC3145 to rebond the OEM rubbers and added a extra piece aft to raise the backside of the muffler off the glass seating area. It was making paste and now is fine after 20 hours use.
