I took out my boat this weekend and as often happens, was enjoying a nice ride when the alarm started blaring in my ear. I've had it go off in 1 second intervals before, and usually a pump or two on the oil primer bulb fixes this.
This weekend, after running for about 2 hours the alarm started sounding in 1 beep intervals, and then continuously when on a plane at about 3500rpm, and would continue unless I pulled back on the throttle. At 2000rpm no alarm--after about 10 seconds at 3500rpm the alarm would sound continuously. From what I've read on this forum, the continuous alarm is either overheating (my temp ranged from 140-175 F--closer to 175 a low speeds and 140 at higher rpms) or fuel blockage.
Because of the numerous alarms I've heard in the past, and the fact that he engine didn't overheated or starved for fuel, part of me thinks the alarm could be faulty. As well, I do have hand tightened wing nuts on the battery terminals, which has been identified on this forum as a common cause for false alarms.
But, the alarm I heard this weekend seems to be consistent with a fuel flow issue. I did notice one of the times the alarm sounded, when I pumped the primer bulb on the fuel line, that the bulb was not tight, and needed a couple of pumps to tighten up--does this indicate a fuel flow problem from the tank?
I'm thinking my next steps, in this order are:
Anything I'm missing?

I'm thinking my next steps, in this order are:
- replace wing nuts
- check/clean fuel filter
- test alarm?
