The water tube on this engine is flared on one end, and it installs from the top of the adapter plate, located under the powerhead. The powerhead and adapter plate will both have to be removed to replace it. Removal of the gearcase will make the job a little easier on reassembly. Once the adapter plate has been removed, the replacement proceedure will become apparent. This can turn into quite a job if you are working on a unit used in salt water. If further assistance is needed, just ask.
The 1992 model, 15 hp Evinrude outboard would use a 50:1 ratio, roughly one pint of 2 cycle oil, to six gallons of fuel.
An Evinrude 25hp outboard, 1985 year model, requires a 50:1 fuel, to 2 cycle oil ratio. This is roughly one pint of 2 cycle oil, to six gallons of fuel.
The 1980 model, 15 hp Evinrude outboard requires a 50:1 ratio, one pint of 2 cycle oil, to six gallons of fuel.
1 pint of oil for 6 gallons of gas 50/1 gas to oil mix
The late model 25 Evinrude suggests operating on a 100:1 ratio. I prefer the old time tested 50:1 ratio, one pint of two cycle oil, to six gallons of fuel. I have never seen an outboard powerhead failure, due to running a 50:1 mix.
The correct compression ratio for a 1992 6hp Evinrude outboard motor is typically around 6:1. However, it's important to verify this with the specific model's manual, as variations can exist based on production changes or modifications. Maintaining proper compression is crucial for optimal engine performance and efficiency.
Johnson and Evinrude outboards manufactured prior to 1965, require a 24:1 ratio. This ratio works out to 5-6 oz. of 2 cycle oil per gallon of fuel.
The mix ratio for a 1978 2 horsepower Evinrude outboard motor is typically 50:1, which means 50 parts gasoline to 1 part outboard oil. This ratio ensures proper lubrication and performance of the engine. Always refer to the owner's manual for the specific mix ratio recommended by the manufacturer.
The woodruff key on a 40 hp Evinrude outboard can break due to several factors, including excessive torque, misalignment between the flywheel and crankshaft, or wear and fatigue over time. If the flywheel is not properly secured or if the engine experiences sudden shocks or vibrations, the key can become stressed and ultimately fail. Additionally, using incorrect tightening procedures or tools can also contribute to the key's breakage. Regular maintenance and ensuring proper alignment can help prevent this issue.

The drain plug on a 70 hp Evinrude outboard motor is typically located on the lower unit, near the cavitation plate. It's often a brass or plastic screw that can be removed to drain the gear oil. Make sure to check your owner's manual for the exact location and any specific procedures for your model. Additionally, ensure the motor is in a vertical position to allow proper drainage.
