1983 Crossflow 140hp Johnson.

Whether you need spark plugs or not is a judgement call only you can make. We are not there to inspect them.

The engine requires Champion QL77JC4 plugs, gaped at either .040 or .030, whichever gap works best for you.

If you tilt the engine beyond the trim range... in all probability it will stall as you are trying to force the engine to pull fuel up too steep an incline.
