I need some help. This is the second time I have received this message from the console. The Drive Shaft Lube is consistently draining from the motor and is constantly needing to be refilled. I have been told this is from driver error. The boat is a Sea-Ray 240 with a 350 Mag engine. I believe this is from running the boat with the wrong tilt. If so could someone please tell me what I am doing wrong to keep from wearing on the shaft.
