This is what i got

From the 1972 65esl72

Block
pistons
rods
crank
and head

From a 78 75843c
carbs
reedplates
crankcase cover
exhaust manifold
all electronics
and everything from the power head mount down.


And yes it works I have ran it several times and it runs better than my dads 2007 70 hp yamaha

I want to get new spark plugs

th 72 called for champion UL77V OR ACVB40FFM
the 78 called for L77J4 or AC M40FFX

I am sure these are not made anymore> the question is do you pick a plug based on the physical design of the head and piston or the electronics firing the spark plug?


So what do y'all think I should do. Also what are the new numbers for these plugs? I searched and all I have done is confused my self in reading the returns.

Please help

The QL77JC4 or L77JC4 will work just fine.
