This past weekend , while at the lake, I was crusing down the lake when my alarm sounded. I immediately shut it down, knowing this wasn;t good. I checked and filled the oil tank under cowling. When I went to restart, alarm sounds constintly. Water flow is good out of peehole, so I know water pump is working properly. Motor starts and runs perfectly. I had heard that the magnet might have fallen off of the low oil sensor into the bottom of tank. I had hit a couple of hard wakes right before the alarm sounded.Any advice would be greatly appreciated! Thanks
