Overheat alarm on Evinrude

It sounds like the fuel sensor is connected and working and you did have a restriction and this would account for the rough running.

The restriction sensor only goes off if there is roughly 8-10"s of vacuum present in the fuel supply line. If you pump the primer bulb up to pressure then there will be no vacuum as you'll have pressure instead. The rough running could just be the gas in the carbs has mostly evaporated and left the oil behind. This is common if you let the engine sit for 2 or 3 weeks or longer with fuel left in the carbs. If both of the wires from the fuel sensor are grounded, then it is obviously not connected. Does your horn normally sound for a second when you turn the key on? If so then you have a 3 wire horn. They can malfunction and alarm even though there isn't a request for it to sound.

The alarm never sounds on start up so I guess I have a 2 wire? I'll start her up again and report back.

Started up again and let run for several minutes... No alarm, no idle problems, sounds strong as usual. Might be a case of needing to "Jiggle the Handle"

Or just run her some.

Roger that. I've only taken her out 4 times since February but I usually fire her up in the driveway once a week or so to keep fresh gas in the carbs. Maybe I got a little slack last month.

Tsubaki and Ferm I owe ya'll some beers. Thanks!

Hell, I had so much faith that you had it fixed that I went out to eat while you tried it!!!
