The OMC outdrive lower unit (Cobra, 400/800 and electric shift Stringer) models will fit in a 26″ x 26″ x 8″ or a larger box.
These boxes can be purchased at most UPS stores and Home Depots. A double walled box is preferred due to it’s strength, but a single walled box will work just fine with the styrofoam packed inside the box.
Please do not use bubble wrap, popcorn foam packing material or towels/rags to use as internal packing material.
These will not provide sufficient protection of the gear box during transport and will most likely result in the gear case being damaged when we receive it.
Purchase insulation Styrofoam – either the white board strips (in the photo the pack of foam is made by Handi-pac available at the Home Depot), or the hard pink insulation board also available at the Home Depot.
Line the bottom of your cardboard box with a piece – and then place your gear box in the box. Make sure all the oil is drained out of the outdrive.
Cut pieces of the insulation board to fit the perimeter of the box on all sides, and piece by piece start to build up towards the gear case.
You’re trying to building a foam barrier between the walls of the box and the gear case that will prevent the outdrive from moving around in the box. It will also prevent damage if the box is dropped during transit.
You can either eye ball the sizes needed as you go along, or use a measuring tape.
After you have sufficiently protected the outdrive with pieces of insulation board, include a note in the box with your contact info and notes.
This note should contain your name, phone number/email, return shipping address and if applicable – any technical notes for our tech.
*These technical notes should describe what issue you were having. Examples would be ‘loss of forward gear, water in gear case, clunking sound when changing gears/slips out of gear, etc.)
If you are sending the OMC electric shift model to be repaired – we rebuild the hub assembly shown in photo with each repair, along with repairing the clutch spring and re-sealing the rest of the unit.
This hub is rebuilt by cleaning up the hub assembly (sandblasting the entire hub, removing the old seals and installing 2 replacement seals followed by an application of zinc chromate).
If you are sending in the OMC electric shift lower unit as a core trade for exchange for one of our rebuilt units – you’ll want to note the number of bolts that holds your swivel housing to the lower unit (shown in photo).
Most models have a ’10 bolt’ pattern for the swivel housing, however some have an 8 bolt pattern.
If you require a rebuilt unit that has the 8 bolt pattern, please contact us before sending in your core.
