Always refer to the owner's manual for any specific recommendations or guidelines.

To determine the year of a Sea King outboard motor with the serial number 65X606482, you can refer to the manufacturer's documentation or serial number lookup tools specific to Sea King motors. Generally, Sea King outboards were produced by Gale Products and the "65" in the serial number typically indicates a model from 1965. However, for precise identification, cross-checking with a detailed database or contacting a Sea King expert would be advisable.

VRO stands for "Variable Ratio Oil" and refers to a fuel-oil mixing system found on certain outboard motors, particularly from Johnson and Evinrude. This system automatically mixes oil with fuel at varying ratios depending on the engine's RPM, ensuring proper lubrication while reducing oil consumption at lower speeds. It helps maintain engine performance and longevity by providing the right amount of oil for the engine's operating conditions.

The impeller on an ESKA outboard motor is typically located within the water pump assembly, which is situated at the lower unit of the motor. To access it, you usually need to remove the lower unit from the motor. The impeller is housed inside a plastic or metal housing that can be disassembled for maintenance or replacement. Proper care and regular checks of the impeller help ensure optimal cooling and performance of the outboard motor.

To remove the lower unit on a 4-stroke 90 hp Mercury outboard, start by ensuring the engine is in the neutral position and disconnect the battery. Remove the bolts securing the lower unit, typically located on the rear and sides, and then detach the shift linkage and any associated wiring. Carefully lower the unit, taking care to prevent damage to the drive shaft and water pump. Finally, inspect the gaskets and seals for wear before reassembling.
