Mercruiser 5.7 EFI goes into alarm in 5 seconds

I have a 1998 Wellcraft 3000. It was summarized earlier this year by the marina and ran great when bringing boat to slip back in May of this year. After it sat for a month at slip I started engine with a turn of the key and after 5 seconds a high pitch alarm went off. The gauges looked good electric, oil, temp. Engine turns over and sounds good until alarm goers off within 5 seconds. Over the winter I did have the a little oil leaking on the out drive so it was taken apart by marina and resealed. With no alarm light lit on dash I don't no where to go. I have had alarms go off before and this alarm appears to be coming from behind the dash and not the little black circle on the front of the dash. Any help or direction would be greatly appreciated!! The engine is a 5.7 EFI with digital ignition.

Thanks
Bill
