1988 mercury 150 xr4 weird issue

[jhogue46140]

Ok I have a constant beeping alarm when I start my motor after a few seconds. I just brought the boat out from winter storage. Temperature is ok. I have checked the oil injection and it is putting out oil like it normally does. It even has white smoke when running which tells me it is getting oil. Ihave checked the spark on all plugs and it is good. The engine runs fine no missing. It started fine after sitting all winter.

The interesting thing is this happened last year I thought I traced it to the temperature sensor and replaced that last year. It didnt stop the alarm. I tried trouble shooting with suggestions from other users here on Iboats. I replaced the oil injection sensor also. One day I go out to do some more trouble shooting and no alarm. Didnt alarm the rest of the year. Now I have started to get it ready for spring and the alarm sounds each time I start it after a few seconds. Any thoughts on what it could be. Does she just need to get warmed up and going. I am completely baffled. Any help will be greatly appreciated. Thanks Doug

Ok I was rereading my post from last year and think we determined it was the alarm module. I had forgotten about this. Here is the link in case anyone has similar issue http://forums.iboats.com/showthread.php?t=264385. Does anyone know the part number for this? THanks Doug
