Tools Needed – Mercury 200 Gearcase Remount
- Ratchet and extensions
- 19mm socket
- Torque wrench
NOTE: We worked on a Mercury 200XL Verado, but the process is the same or similar for most outboard motors.
How to Remount Mercury 200XL Verado Lower Unit
Step 1. Slide the driveshaft housing spacer back over the driveshaft and onto the lower unit.
Step 2. Clean and grease the driveshaft splines, and apply a thin coating of grease to the entire length of the driveshaft. Also, grease the shift shaft splines.
Step 3. Slide the lower unit up over the four mounting studs protruding from the driveshaft housing.
Step 4. Take the speedometer hanging from the driveshaft housing, then reach down into the lower unit and reconnect the speedometer tube.
Step 5. Slide the lower unit up fully, making sure the shift shaft is aligned and engages with the driveshaft housing.
Step 6. Install and hand-tighten one of the 19mm mounting nuts and washers onto the mounting studs to temporarily hold the lower unit in place.
Step 7. Install the other three 19mm nuts and washers onto the mounting studs, then install the 19mm lower unit mounting bolt up through the rear of the gearcase.
Step 8. Torque the four nuts and the mounting bolt to 55 foot-pounds.
Step 9. Apply blue threadlocker to the anode bolt, then reinstall the anode under the rear of the gearcase or replace it with a brand new one. Torque the anode bolt to 40 foot-pounds and you’re done.
PRO TIP: Tape the anode bolt to the socket just enough to prevent it from falling down through the driveshaft housing and spacer as you’re installing it.
