This engine is clean with about 250 hrs on it, but it sat for a while. I bought it three years ago, and had the optical ignition pack replaced, cleaned or replaced some wiring, connectors, ignition switch, kill switch. First year it started and ran great. Third year it started first time, but died once while underway in rough water. Ran great other times.
This year it has been hard to start, engine cranks - seems like no spark with gas/oil coming out unburned from exhaust. Noticed the little beep status check of the SLOW system doesn't come on anymore when turning the start key. I replaced the battery, cleaned the plugs, checked the ignition switch with a meter. Checked the warning horn and it works.
When I do get started, the last three times out the engine will just die like I killed the engine after being underway for 3 to 10 minutes. Two out of three times it started right up again, sometimes dying again within a short time. Once it goes through this routine, the engine will run and start up fine the rest of the day.
The last time it took it out it started right up and idled fine. After getting on plane and cruising around 1/4 mile at 30 mph, the engine dies. Started up but died 5 minutes later. It took awhile but I eventually got it to start by disconnecting and reconnecting the battery, turning up the red lever (turn off fast idle start) and advancing throttle at carbs. I don't know what if any of this helped. It wouldn't idle, but ran when holding throttle back. Then I turned the red lever down and it started up and idled fine.
Engine ran fine the rest of the day, but noticed MPH and tach gauges were sometimes reading low or not at all.
Any ideas on what this could be, or anyone experience this? Thank you for your help.
