Hello All-
I have a 2000 Yamaha 200 HPDI, and my question has to do with the water pump, particularly when it's time to flush. When I have it in the water, it pees just fine at idle and WOT. Good solid stream, no overheating problems, no alarms, and when it's put up on the rack, the motor does not feel like it's overheating. The problem is when I put the flush muff on and crank it, it will not pee. I have tried varying the amount of water pressure from the hose (full, medium, & low), and no pee. I do not let it run more than just a few seconds when it doesn't pee, and I shut her off. When I hook the hose up to the flush port, it pees without cranking just from the water hose pressure. I have run the motor on the flush port, and I have read that you shouldn't do that. I have also read that the larger Yamaha motors don't like to run on the flush muffs, but I don't know how much stock to put into that. Any advice and help here will be greatly appreciated in advance. If I need to provide more info, just ask.
Thanks,
