I get this WIRE core at a good outboard repair shop !!-----It should be easy to find WIRE core 7mm spark plug wire.-----Make sure you get WIRE core and don't read the fancy script about these NAPA wires.
Flywheel in the picture does not look like the flywheel off a 1976 model.----Do not believe there was a 25 HP in 76.-----Should be easy to find a flywheel.
Well ---the 6 injectors do not all fail at the same time.----Best to find another shop.----May not be easy to find.----You have looked at fuel filters.-----Charged and tested your battery ?-----Do not crank and crank on this starter as it is easily damaged.
Hurry----Run to your local boat shop and see the steering set up common to most boats.-----Then ask for that drag link for the steering.----They might have a box full under the work bench.
The pressure tanks were very good and reliable.-----You pump the primer to fill the carburetor with gas.----As soon as motor starts the crankcase compression is used to put pressure on the fuel.-----Fuel then flows to the carburetor.
No surprise to me that a motor with issues is put up for sale.-----Look into the procedure for synchronizing throttle opening with spark advance.----Check gear oil too.

Outline the colors of the wires going from the powerpack to the coils.---What is the stripe color going to cylinder #1 , #2 , #3 , #4 ?-----Is the lever on the ELECTRIC PRIMER VALVE in the run position ?
The Johnson 10 HP QD models came out in 1949.-----Remote pressure tank and full gearshift.----Earlier motor had the gravity feed tank and no gearshift.
