Checking your oil level.
The oil level check procedure for your Yamaha four-stroke outboard is a bit different than the procedure for your car. It’s easy to get an accurate reading if you follow this procedure:
- Start and warm the outboard to normal operating temperature, then shut it off. Stop the outboard.
- Tilt engine up halfway and allow to rest for 5 minutes to thoroughly drain the oil back
into your outboard’s crankcase.
- Trim the outboard back down to level.
Tip: You can place a small level on top of the anti-ventilation plate to help you determine when to stop.
- Pull the dipstick, wipe the oil from it, and re-insert it in the crankcase. Then pull the stick again
and check the oil level. This helps ensure proper venting for accurate indication.
- At the proper oil level, the oil should be halfway up crosshatch pattern on the dipstick.
Tip: The top and bottom of the crosshatch pattern on the dipstick do not represent “high” and “low.” The correct oil level indication is at the mid-point of the pattern. Use caution when filling or adding oil. Yamaha four-stroke outboards have a tapered oil sump design (smaller at the top than the bottom), so the closer the oil level is to full, the faster it fills. Therefore, add oil slowly and in small amounts, and do not attempt to “top off.” Do not allow the oil level to surpass the upper portion of the crosshatch pattern. Doing so may result in aeration of the oil, reducing lubricity and oil pressure, and may cause eventual engine damage.
How do I choose the right oil?
Marine engine oils are so different in their requirements that special levels of certification exist: FC-W® (four stroke) and TC-W3® (two stroke). These represent the minimum standards of the National Marine Manufacturer’s Association (NMMA®) for marine engines. With their high quality and advanced formulations, all Yamalube 4M and 2M oils meet or surpass all of these requirements. Using Yamalube is best for your Yamaha outboard, but whatever oil you choose, make sure it is the correct type and viscosity and that it carries either the NMMA® FC-W® or TC-W3® label.
What Yamalube oils are right for my outboard?
Yamalube 4M FC-W® Reformulated to better protect your investment from the harsh effects of cold starts, hours of trolling and high-load, high-speed operation, its special anti-corrosive additives are particularly suited for the harsh marine environment.
- 5W-30 Full-Synthetic—great for high-performance outboards like our V MAX SHO® model
- 10W-30 Mineral Base (conventional)—ideal for all Yamaha outboards and environments
- 20W-40 Mineral Base (conventional)—suited for large outboards in consistently warm climates
Tip: 20W-40 weight is not for use in 4.2L V MAX SHO models.
Tip: Your Owner’s Manual is the best place to look for your recommended viscosity.
Yamalube 2M TC-W3® Yamaha-formulated and NMMA®-approved, it provides outstanding protection for two-stroke, water-cooled outboards, with its special blend of additives that help combat ring stick, corrosion, varnish and wear. It’s a standard by which other two-stroke oils are judged.
Aren’t all oil filters pretty much the same?
Outwardly, perhaps. But it’s what’s on the inside that counts most. Yamaha oil filters are manufactured specifically to protect Yamaha engines, using only the finest components and construction methods available. This includes a special filter media and metal filter media bases (instead of cardboard), to help them achieve a level of durability and filtration far superior than most “off-the-shelf” oil filters. From the quality of the materials used to their high-quality construction, they simply outperform and out-protect most aftermarket alternatives.
