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.

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.
How did this motor run for you last season ?-----If throttle plate opens too early the motor will be very unhappy.-----The primer is better than choke plate in my opinion.
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.
Those Martin motors were actually very good runners.---Well built smooth and quiet.----But they fell by the wayside as they were expensive.----No separate tank or gear shift.
The steering on a 1974 model Evinrude hooks up to the tilt tube.--------There should be no need for that adapter bracket,-------That bracket was used for Evinrude motors 1972 and older !
