Hi all - I recently bought a used boat with a 98 Evinrude 115 hp. I knew it had issues before I bought it. The previous owner said the rectifier/regulator was bad b/c the battery was overcharging and when the engine warmed up a check engine light would come on and the engine would stumble. He included a new one in the purchase and I installed it. It ran fine on muffs for 20 minutes in the driveway. Took it to the lake today and it idled fine for 15 minutes while we were waiting on a buddy to get there. We pulled away and slowly increased the throttle. Got up to 30 mph and then the alarm sounded 20 seconds later, check engine light came on, and the engine stumbled back down to idle. It did this multiple times, would sound like it was running out of gas, and eventually it wouldn't even start. Plenty of oil in the tank and bulb is hard. Plenty of gas and the bulb feels pretty hard. We took off the cover and listened for the fuel pump once we turned the ignition - nothing. We disconnected the gas line after the fuel pump while pumping the bulb. No gas made it past the fuel pump. We waited 30 minutes or so while lounging around and the fuel pump finally kicked on enough for us to make it back close to the dock and then wouldn't start again. When I brought it home the fuel pump would not cut on.
My question is do I need to replace the fuel pump or are there smaller items within it? Also, do you think the fuel pump could be causing the engine alarm to sound? I'm thinking that since the pump controls the oil and gas, the alarm may be sounding b/c the engine would be getting oil if the pump is cutting in and out. Any help would be appreciated. I also have the repair manual but wanted to see if someone has encountered this before. Thanks for the help.
