1976 4 cyl OMC 140 hp, OMC electric shift drive
Stupid newbie question......... What spark plugs do I use??
When I bought this boat, the engine was already out and partially disassembled. I rebuilt the engine, and am getting ready to put it back into the boat. The spark plugs were all missing when I started this project, so I didn't have anything to go off of to get new plugs.
NGK lists these here http://www.ngksparkplugs.com/part_finder/watercraft/step3.asp
1985-1973 Stern Drive 14mm Hds Taper Seat
And then a bunch of TU, DU, GU, etc..... but none of those have years.
Thanks in advance
