As I posted last week, I've rebuilt all my carbs now (Johnson 130 Oceanpro) and everything has seemed to be just fine. No leaking, good fuel delivery, boat performing normally, even yesterday. Today I went out for a hate-being-bored cruise which was at slow speeds (no planing) for about 40 minutes. I then got into a WOT area and let 'er rip (did this twice yesterday). About 3 minutes after planing and adjusting trim the engine made a weird groaning sound and then stopped. Luckily for me there were no ginormous cigarette or trawler type boats bearing down on me. My first thought was I caught a crab trap buoy that was submerged. I raised the motor and checked the prop, all looks okay. I lowered the motor and tried to start it but it wouldn't hardly turn over. I checked the battery connections; fine. I took the engine cover off to view the starter and fuel filter, then I tried to start it again. It fired up but was rough. I replaced the cover then turned right around and headed home (1.5 miles, slow speed). The motor did not sound right at all. As I approached my lift and had it in neutral it was very rough and stalled as I floated over the lift. My next thought was that the oil was low (oil injection system) but the alarm light and sound didn't alert me to that, which it has in the past. My oil tank is crammed next to battery #2 so I can't easily check it visually. I rely on the "low oil" and "no oil" alarm lights and sounds. To be safe I added more oil. I could hear it flowing into the tank, so it was either very low or quite possibly empty. For the record, I add oil about every 4th trip just to be safe. No long trips lately so not sure what's up. Anyway, I tried repeatedly to start it while on the lift with lower unit submerged and it starts up but dies within 20 seconds. I checked fuel-water separator; clean. I just replaced the bulb 2 days ago and rechecked those ring clamps; fine. Viewed the fuel in the filter; looks clean. Spark plugs were replaced about 8 months ago. New fuel is added weekly and I use the Stabil with Ethanol Treatment at every top-off.
So, what could have made the engine just stall at high throttle speed? I'm sure the reason is why it won't start now. Maybe a failing fuel pump? Could it have been low/no oil?
I'm not going to restart it until the morning when the engine is cool so any advice would be much appreciated!
Sorry for the long post but I wanted to include as much detail as reasonably possible.
TIA!!
