I have a 2012 Suzuki 150 with about 600 hours, indoor stored and in great shape for a salt water engine. We've had it since 2018 and it has always run fine.
Yesterday, backed the engine into the water at the ramp, fired it up, backed down a bit more and the boat came off the trailer with a bit of reverse thrust. Docked and left it idling while waiting for my wife to return from parking the trailer.
She got back and I backed away from the dock. Everything was perfectly normal up to that point, including a few minutes at idle. I paused away from the dock to transfer bait into the livewell and when I put it in neutral, it stalled and beeped. Not sure in which order, but I thought the beep came first.
Tried to restart and it wouldn't. Gave it some neutral throttle and it fired up and sounded normal. Back to idle, it stalled. No beep this time, and no warning lights on the tach.
I repeated this a couple of times, also trying pumping the fuel primer bulb. It seemed suspiciously thirsty when pumping the bulb while running it at high idle. Still stalled immediately when the throttle was put back to idle.
Pro tip: it's best to have this kind of problem immediately upwind of the boat ramp dock. We came home and took out one of my back up boats instead, but this is our main fishing boat and the weather has just turned bearable in this part of the world.
What do you think is wrong? Thanks for any help!
