IMPORTANT: Always use dipstick to determine exactly how much oil is required.
5. Add recommended engine oil to bring level up to the bottom of the OK range on the dipstick.
6. With the boat at rest in the water, check the oil level and add specified fluid to bring the oil level up to, but not over, the full
or OK range.
NOTE: Adding 0.95 L (1 qt) of engine oil will raise the level from the add mark to the top of the OK range.

7. Start the engine, run the engine for three minutes, and check for leaks. Stop the engine. Allow approximately five minutes
for the oil to drain into the oil pan. The boat must be at rest in the water.

Transmission Fluid

Checking While the Engine is Warm

1. Velvet Drive Transmissions – Stop the engine and immediately check fluid level by turning T‑handle counterclockwise, to
remove dipstick. Fluid level should be up to full mark. If low, add specified fluid through dipstick tube on transmissions.
2. Walter V‑Drive Transmissions – Stop the engine and remove the dipstick to check the level. If the fluid is below the top
(full) line, add the specified fluid through the breather elbow. Do not overfill. Reinstall the dipstick with the cap fully seated.

Checking While Engine is Cold

NOTE: Cold fluid level check: To ease checking the fluid level, the dipstick can be marked or scribed with a cold level mark.
1. Follow the procedure for the warm fluid level check, then allow the boat to sit overnight.
IMPORTANT: Be sure to push the dipstick all the way down into the dipstick tube when checking the fluid level.
2. Remove the dipstick, wipe clean and reinsert.
3. Remove the dipstick, observe the fluid level and mark the cold fluid level.
4. Reinstall the dipstick, tighten the T‑handle securely. Do not overtighten.
