They didn't make the 85 hp in 1969.What is the engines model number?

Surface gaps are better for sustained high speed. Conventional L77JC4s are better for all-around operation. Either would be appropriate for a thru-prop exhaust 85.

Well shut my mouth.I'm sorry.My plug source didn't list 69' 85 hp engine.Not sure about the specific plug it calls for still looking.Someone else may pipe in that knows for sure.

No NGK's in a carb'd OMC. Merc and Yamaha, yes. Not OMC.<br /><br />Keep in mind that pistons may be a bit difficult to find for that motor.
