Installation Notes

  1. Disconnect the battery and ensure the engine is off and cool.
  2. Remove the propeller and then the gearcase/lower unit assembly per your service manual.
  3. Carefully extract the old propeller shaft oil seal using an appropriate seal puller, avoiding damage to the housing.
  4. Clean the seal housing thoroughly, removing any old sealant, corrosion, or debris.
  5. Lightly lubricate the new seal with marine grease on its outer edge and inner lip.
  6. Press the new seal into place evenly using a suitable driver or socket until it is seated correctly and flush.
  7. Reassemble the gearcase and propeller, torquing all fasteners to manufacturer specifications.
  8. After reassembly, check gear lube level and inspect for leaks after the first use.

Troubleshooting & FAQ

How do I know if this oil seal will fit my Suzuki outboard?

Verify your engine model and year against the compatibility list on this page. This seal fits specific Suzuki DT 2-Stroke models from 2HP to 9.9HP (1977–2005). Always compare the listed dimensions (10mm x 26mm x 9mm) with your old part before ordering.

What are the signs of a failing propeller shaft oil seal?

Common indicators include visible oil leaks around the propeller shaft area of the lower unit, water intrusion into the gearcase (milky or discolored gear lube), or a noticeable film of oil on the water surface near the outboard.

Is any special tool required for installation?

A seal puller is recommended for safely removing the old seal without damaging the housing. To install the new seal, use a press or a correctly sized socket or seal driver to ensure it seats evenly without distortion.

How often should this propeller shaft seal be replaced?

Seals should be inspected during regular lower unit service (e.g., water pump replacement) or at least every 1-2 seasons, depending on usage. It is best practice to replace them whenever the gearcase is disassembled or if any signs of leakage are present.

Can I use this seal on a model not listed in the compatibility chart?

We do not recommend using this part for models not explicitly listed. The manufacturer data only confirms fitment for the years and models provided. To ensure a proper fit and prevent gearcase failure, only use this seal if your model is listed in the compatibility table.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
