"I have a 1997 DT225 that idle
"I have a 1997 DT225 that idles / rev's great in the yard on the hose. Tried to take the boat out yesterday and just about the time I got on plane, around 4,000 RPM, it suddenly bogged down to around 2,000 ( was too busy trying to avoid traffic in crowded ICW to pay real close attention) and cut off. When I tried to start it back up it acted like the batteries were very weak. The batteries are new and fully charged. It would kind of crank a revolution, pause and crank, pause etc. I let it sit for about 15 minutes while waiting on anchor for TOW-Boat to show up and when it finally did crank it had a rough idle around 1,000 RPM. I turned it back off b/c it didn't sound right to me. when I got it home, I hooked the hose up and it cranked normally but backfired right away and fired right up. So I am guessing it's a fuel delivery problem but have no idea how to find out on an EFI motor. The lower unit was just re-sealed for a propshaft leak and the mechanic said everything looked good. It has a good "pee" stream and the thermostat was open, it was dumping water out. I never got a water flow alarm on the guages. Sorry for the long post but i am desperate to get out fishing again and don't want to blow all my gas $$ at the shop.
Thanks - Joe"
