We experienced complete and sudden loss of transmission oil pressure this past weekend.
The transmission is a Borg Warner and the engine is a 410-8 Perkins.
I have no prior experience with these transmissions and I am in need of some direction on the steps and order to trouble shoot the problem.
My first thoughts were that it was a broken hose but I have not noticed any large quantities of transmission fluid in the engine compartment. My next thought was that the pump failed.
The boat is equipped with a mechanical transmission oil pressure gauge with high and low point alarms. The pressure was operating within the normal limits until the sudden and complete loss of pressure.
I was running about 1200 - 1500 rpm when the incident occurred.
So glad we had Boat US membership. Tow bill was $1,800.00
Thanks in advance for your help.
Don
