10 ways to keep your OMC electric shift outdrive running

OMC electric shift stern drives have been in providing
service for over 50 years. There installed on large 40 foot houseboats, barges and smaller single engine boats 26 feet and
down. These heavy duty unit can stand the test of time if and only if you stay with in the parameters of the outdrive.

  1. Check your engine ideal speed this out-drive is one of best built lower units ever made how ever a sure way to
    kill it is with high ideal speed , Please check your manual for exact rpm. Normal operating rang is 500 to 600 range. Most
    V8 engines 1974 to 1977 that i owned did great at 550 to 570 RPM. This can be checked with a low end rang car tack sold on
    ebay and auto stores. Do not make the mistake of thinking the engine sounds good or an old 40 to 50 year tachometer on
    the boat is still working fine as most do not.
  2. Add a carburetor return spring or door closing spring form the hardware
    store to insure the gas cable returns to the same location and without delay each time. The small spring on carburetor is
    not very reliable.
  3. Change 2 wires coming from forward / reverse shifter to the engine compartment out-drive connection
    and place plastic tie wraps on the connections.
  4. Add one new wire going from negative on battery terminal to outside
    of out-dive lower unit case to maintain integrity of the ground.
  5. Check shifter switch contacts by taping on the shifter
    or just change the micro switch to a new one is the best solution if you don’t have test equipment.
  6. Change starter
    switch and wire that leads to common on forward / reverse shifter.
  7. Use an aluminum propeller that the fins can break
    if you hit a rock
  8. Stay away from stainless steel propeller as torque from start to forward and forward to reverse
    can break clutch spring
  9. Go easy on throttle when going into reverse gear at dock as this action pull outdrive away
    from boat wearing out the ball gears,
  10. Use Type C oil only in electric shift lower unit and 70-90 weight oil in upper
    gear-case and intermediate housing. Thicker oil will help keep the bearings in upper gear-case running longer. Note some repair
    manuals have error in regards to type C oil in the upper gear-case.
