We bought a boat with a 1993 Force Motor and they stated it had a bad starter he did start it by pull starting it we replaced the starter and it only had spark on one cylinder after doing some checking we replaced the switch box we now have no spark any suggestions?

If you replaced the CD box with either a new one or a known good one you need to check the wiring. Check for a missing ground. The box must be grounded to the mount and the block. Also check that the kill switch is not tripped and the black with yellow trace wire is not shorted. Black with yellow trace is the kill wire It you remove it from the terminal and insulate it the engine should have spark. (assuming all other components are good)
