1. Fill unit with manufacturer's required gear oil to recommended level.
2. Adjust RPM at idle to manufacturer's specifications.
3. Proper shift adjustment is essential.
4. Jumping out of gear: If the unit will not stay in gear, the clutch dog has probably been rounded off. Rounded clutch dogs are caused by, but not limited to, improper shift cable adjustment, inadequate shift travel, idle RPM too high, and/or shifting too slow. Rounded clutch dogs are not covered by warranty.
5. Avoid full throttle starts.
6. Do not operate at constant speed for extended periods.
7. Shift into forward gear a minimum of 10 times during break-in, with moderate engine speed after each shift.
8. Do not exceed 75% of full throttle during the first 5 hours of operation.
9. During the next 5 hours, full throttle should not be maintained for long periods. [links]

When purchasing either an upper or lower assembly separately, the opposite piece must be disassembled and cleaned by the service center in order to validate the warranty. This provision is due to the cross contamination of the oil.

Depending on the boat, it may make sense to get up on plane, and then pull back the throttle to get the rpms down. basically it depends on how low your rpm's can be and still be on plane. If the number is 3,000 then run up to 2500, then for the 3,000 rpm hour, go past it to get up on plane, then pull back to 3,000. Make sense?

SEI's Lower units come with a three-year, fault-free warranty which means that the lower unit will be covered for any failure that requires the lower unit to be replaced or repaired. This is truly a remarkable warranty. Hit a rock, suck up some fishing line, drag the lower unit up the boat launch by mistake, it does not matter, the lower unit will be covered by SEI's fault-free warranty. [links]

You should change the gear lube every 100 hours or every year. Also check to see if there is any water in your drive. You should also replace the impeller once a year. here

Do I need my old drive as a core?

We ship the units in halves only. A complete unit is too heavy to ship without shipping damage. You will receive two parts to join.

It is the same if you change just the upper, lower or both. For the first 5 hours do not run a constant RPM. Vary the RPM's every 5 minutes or so. Do not exceed 75% throttle for the first 5 hours. Shift into forward and reverse a minimum of 10 times in the first 5 hours. For hours 5-10 you should do short runs at full throttle. After 10 hours normal operation can resume. Change the gear lube between 10 and 20 hours.
