I just had to replace mine... this may be a lame answer but since there is none here at all!! We took a workng one from another engine that fit and it caused the motor in question to return to both cylinder full power. Have no idea about an electrical test. My cd unit was available to DEALERS ONLY online...
does the lower unit need to be removed to replace the water pump on a 1995 Johnson 115 hp outboard engine
An outboard engine is an engine attached to the outside of a boat. An outboard engine is usually contained within its own casing. By contrast, an inboard engine is enclosed within the hull of the boat itself.
To rebuild a lower unit on a 40hp Mercury outboard, start by removing the lower unit from the engine by unscrewing the bolts and disconnecting the shift linkage. Drain the gear oil and disassemble the lower unit, noting the arrangement of parts. Replace worn components such as seals, bearings, and the water pump, then reassemble the unit, ensuring all parts are properly aligned. Finally, refill with the appropriate gear oil and reinstall the lower unit on the outboard.
1965
Outboard means "outside", for example, an outboard motor as opposed to an inboard engine.
A Johnson outboard, model number CD-13A, would be a 1956 year model, 5.5 hp.
To find the year model of a Mercury outboard, you need to know two things, the serial number, and the horsepower rating.

how do u remove the lower uint on an outboard motor? Depends on the outboard. Some Johnson/Evinrudes required that the powerhead (engine) be removed first for example. Look for a service manual for your particular motor on ebay, and it will tell you all you need to know to avoid problems.
Outboard engines work by combining a gasoline engine with a propeller system that is mounted on the outside of a boat's transom. When the engine runs, it powers a crankshaft that drives the propeller, creating thrust that propels the boat forward. The engine can be tilted and steered, allowing for maneuverability and control over the boat's direction. Additionally, the outboard unit often includes a cooling system and a fuel delivery system to ensure efficient operation.
If the horsepower of your Mercury outboard lower unit is 75 and below, SAE 80W90 Gear Lube is recommended.
No, the lower unit from an 85 hp Force outboard motor will not fit a 125 hp Force outboard motor. Lower units are typically designed specifically for each engine model and may have different gear ratios, bolt patterns, and dimensions. It's best to match the lower unit with the correct engine model for proper fit and performance.
