BF50 Honda ~ beeps when throttled up

Late 90's Honda 50hp - replaced water pump and on test run the control box beeps (with solid green light) when the throttle is advanced. It beeps steadily until throttled back to lower rpm. Any thoughts? I thought maybe the shift linkage is a bit out-of-adjustment?

Is this a continuos beep tone (not beep, beep, beep, etc)? If so, there should be a red light on to indicate an overheat.

I know you just changed your water pump, but did you use the right pump? Did you pull the thermostat and check it and backflush the system from the thermostat housing? If there were pieces of impeller missing, did you find all the pieces? Did you look under the water pump all the way to the water pickups? Many times, the pieces will fall below...clogging the system.

If it is a beep, beep, beep, etc...then you have your motor trimmed too high.

I do not know of any reason a misadjusted shift linkage would be causing this problem.

You sound like you have the model where if the engine is trimmed up and put in gear and throttled on the alarm will sound.

These have been known to fault and alarm in any position when throttling up

You may need to change the trim module http://www.boats.net/parts/search/Honda/Outboard%20Engine/2000/BF50AY%20LRTA%20MARINE%20ENGINE%2C%20JPN%2C%20VIN%23%20BAZS-3200001%20TO%20BAZS-3209999/REGULATOR%20%2B%20REMOTE%20CONTROL%20CABLE/parts.html

Or possibly the trim sender

Curious - Did Hondadude's and/or gazzz's solutions resolve? Thanks.

I had the same problem, disconnected the trim sensor and it stopped.
don't really know why you need this feature anyway ?

Just started a new thread. I think that the trip sensor has stiffened up. At 120$, it may be a disconnect until I get that trip gauge in. Still troubleshooting.
