Lower unit oil how much

If yours is stuck, try soaking the plug with penetrating oil, like WD, and letting it work overnight. Finally, you can try using heat from a heat gun.

Be patient and persistent, but try not to strip the slot in the plug head because drilling out the plug will be a major headache.

Snatch it away as the oil begins to slowly drip out. Then remove the upper vent plug screw, usually located above the cavitation plate on the starboard side of the lower unit, and the oil will gush rapidly out of the drain hole.

Give the oil plenty of time to drain completely, ideally for an hour or more. The lower drain plug screw often has a magnetic tip. Inspect the oil in the pan. Here is what Amsoil has to say about their Marine grade Synthetic oil. Same basic oil , just better additives. Lower unit oil has water resistant additives that help the oil adhere to the gears when slight amount of water gets introduced whereas standard gear oil does not have these additives.

This is a drain plug. When removed from the bottom of your boat's transom, water drains out. When inserted in the transom, it prevents water from coming back in. More than once I have gotten the boat partly off the trailer and noticed water pouring in the back. It is best not to mix different oil brands or weights. To refill the lower unit , insert the bottle or tube into the bottom drain hole and slowly squeeze the bottle to force the oil into the lower unit.

It provides outstanding protection from cold start to operating temperatures, making gear selection and engagement smoother and easier. While some manual transmissions now use automatic transmission fluid ATF , most manuals use a variety of fluids for optimal engine and gear function. Log in.
