Need help!
--I am getting a low oil level indicator with a full transom tank full of oil. The level of the engine reservoir drops and the pump does not engage to re-rill it. I have tried using the manual emergency switch to force the pump, but that does not engage it either. Are there any other troubleshooting tips before i spend $500 to have a mechanic tell me i am an idiot?

PS...I also get a water temp alarm when idling as well as the trim indicator gauge always registers one bar from "full-up" position...

The middle oil level light(add oil light) in tach means need to add oil to remote oil tank in boat, but emergency switch on motor should make oil transfer pump run. The low warning light or bar(red light) means that engine oil tank is low, warning buzzer will come on and engine will reduce to 2000 rpm's.
If middle light or bar is on and emergency doesn't work then wire at boat oil tank may be unplugged is bad wiring.
Need to put new water pump in it and check trim sender on engine bracket is not stuck.
