A few weeks ago I spent most of an afternoon first cleaning up and then trying to get a 12 year-under-an?outside-tarp-stored 35 hp jet outboard motor to start (Johnson model J50JETB (1993) ? two cylinder, 737 cc 50 HP power head driving a 35 hp-rated jet foot). Its carburetor bowls and lower crankcase were full of oil which strongly suggested that some part of its mysterious ?variable ratio oil? (VRO) oil/gas mixing system had failed before it was so-stored (abandoned). Since the total retail cost of all of the parts comprising that system (VRO, oil tank/electric pump/hoses, etc) is well over $800 and it serves no useful purpose to most people, I replaced it with a generic Chinese-made, carburetor-type (4-6 psi) electric fuel pump (EBAY $9.24 free shipping) which now feeds the engine?s carbs & primer with a 50:1 gas/oil mixture. The electric pump is turned ?ON/OFF? with a 5 amp-rated (the pump only requires 1.3 amp) single pole, single throw toggle switch mounted in a 3/8? hole drilled through the front of the motor?s cowling (the pump?s positive (red) lead is connected to the starter solenoid?s battery post & its negative wire to one side of the switch the other of which is grounded.) It works like a charm.
