I have a Mercruiser 3.0L with SN 0W334198 in a 2005 model Sun Tracker pontoon which just started showing no oil pressure on the gauge. I just replace the starter/solenoid and am wondering if I disconnected a wire to the oil pressure sender.
I need to know where the oil pressure sender is...
I have an old (I believe it is pre-1979) Mercury outboard that is a 9.9 HP using NGK B7S spark plugs. The color of the motor is white.
What is the correct spark plug gap for this motor and plug?
How do I determine the date of manufacture?
Thanks.
