SYNTHETIC OIL 80W90 15L

Function and technical context

80W90 synthetic oil acts as a transmission lubricant in gearboxes, tailshafts and transmissions of outboard and outboard marine engines, protecting the gears from the friction, wear and corrosion caused by the marine environment. Formulated with a high-quality synthetic base, this lubricant maintains a stable viscosity both in cold starts and under high thermal load, guaranteeing a continuous protective film between moving metal elements. Its 80W90 viscosity classification makes it especially suitable for transmissions that demand a fluid with high shear resistance and good fluidity under variable working conditions. A transmission lubricant that is degraded or contaminated with salt water can cause premature wear of pinions, pitting of gears and, in extreme cases, complete seizure of the transmission, with the costly breakdowns that this entails.

When to replace this lubricant?

The most common signs that the transmission oil needs to be renewed are the appearance of a grayish or milky color in the fluid (a clear sign of water ingress), visible metallic particles when draining or a burnt smell, symptoms that indicate that the lubricating film no longer properly protects the gears. As a guideline interval, marine engine manufacturers recommend replacing the transmission oil every boating season or every 100 hours of operation, whichever comes first; In areas with salt water, the review should be carried out in advance. Changing the transmission lubricant preventively at the beginning or end of the season is the most economical measure to avoid major repairs on the high seas or in a navigation area far from a workshop.
