I recently bought a boat with a 1994 Mercury 100 hp outboard serial number 0G050058. Previous owner stated the boat had not been ran in a year. Everything sounded and worked great while running on muffs.
First time I had the boat out everything ran great, no alarms, but after we stopped for a short time and tried to restart the engine it would die at idle, solution to this was to use the high idle and then quickly shift into gear after bringing it back down to idle. This problem only occurred once during the first trip.
Second trip, after leaving the dock a constant beep alarm came on, from what I've read this is the overheat alarm. The engine had only been on for a couple seconds so I don't think there is any chance it was overheating. The alarm went off after about 30 seconds of idling. Ran the engine for a couple hours with no problems. Later in the day the alarm came back on while idling, as well as after letting the engine sit without being run for about 30 minutes with the key in the on position and the engine off. Also the same problem I had the first trip with trouble starting happen twice during this trip. Decided to call it a day and while heading back to the ramp the engine lost a noticeable amount of power, it sounded and felt like not all cylinders were firing, the power would intermittently kick back in, the increase in power was noticeable. The alarm was not on when this happened. Eventually the power came back and everything felt fine. While idling before loading the boat at the ramp the constant alarm came back on.
From what I've read the trouble starting could be that the carburetors are gummed up, would this also explain the short loss in power? What about the constant alarm? This is my first boat/outboard, I am quite mechanically inclined but have zero experience with outboards or boats in general. I'm planning on checking the compression tomorrow and checking the spark plugs. I have looked for carb rebuild kits but can't find one for this engine that includes the floats and needles, maybe I am looking in the wrong place.
Carburetor kit I found, will this work and would I just reuse the old floats/needles?

I am also planning on ordering the service manual. Is this the correct manual for my engine?

If anyone could give me any insight as to what is happening or any guidance it would be greatly appreciated.
