Ignition Timing Adjustment
2014 BF75/BF100/BF8A Outboard Motors
Contact Breaker Type
Remove the engine cover.
Connect a timing tester or ohmmeter as shown.
Rotate the flywheel to align the "F" mark on the flywheel to the index mark on the starter case. At this time, the contact breaker points should just start to open (15° B.T.D.C.).
To adjust the timing, loosen the breaker plate locking screw and move the contact breaker plate to achieve correct timing. Re-tighten the locking screw.
Rotate the flywheel one full turn, and check ignition timing for the other cylinder. Re-adjust the contact breaker points, if necessary, so the ignition timing will be as correct as possible for both cylinders.
CDI Type
NOTE:
A CDI system does not require adjustment, except when the CDI unit is replaced and/or the pulser coil is removed . The timing remains unchanged as long as the set parts remain undisturbed.
To set timing, align the flywheel "T" mark and the punch mark on the camp pulley as shown, then install the timing belt.
Rotate the flywheel on complete turn and align the "F" mark with the aligning mark.
Loosen the two screws and move the pulser coil so the marks on the coil and advancer rotor are in-line.
