Ask Boat Guru about thisSpec · Optimax 200 primary coil resistance is 0.3-0.6 ohms.
Diagnostic · Weak-spark no-start often tracks back to coil or supply voltage.
Spec · Source-less curated ignition observation.
Diagnostic · Test: Attach fuel pressure gauge at rail and crank for 10 seconds. Expected: 36-40 psi while cranking. If fail: DTC102
Diagnostic · Test: Verify spark at each cylinder with an inline spark tester. Expected: Bright spark at all cylinders while cranking. If fail: DTC101
