I recently picked up a '78 Evinrude 140. Its got NGK B7HS-10 plugs in it. Wondering if anyone knows the Champion plug. I have not picked up the manual yet. I think a QL82YC will be correct just not sure.

Like I said, don't have manual yet. I could also use lync and synch specs. I am familiar with procedure just need max timing and such.

Did a sea trial and hit over 70 on gps. Hafd to feather the throttle on. Solid little boat.

Any one have a wiring diagram for putting the trim on the steering wheel? It would make this a bit safer.

Its on quite a cool little 14' Stuery. Should be a fun little boat when I am done with it.

Wow! 70mph in a 14 footer is flying! Sorry can't help with the specs.

The recommended plugs are Champion UL77V or L16V Surface Gap plugs
