The 90 hp Johnson outboard is not shipped with a propeller installed. The correct size is determined, and installed, when the engine is rigged on the boat.
A 4 hp Mercury outboard, produces a true 4 hp, rated at the prop.
Sometimes the center of the prop breaks loose and slips or the splines get stripped. Also check to make sure you have the correct pitch prop for that motor and it is fastened securely.
In neutral, the propeller shaft is not engaged with any other part of the motor so the prop will spin freely. You'll often see this when a boat is being towed down the highway - the prop is spinning the same as a windmill does in the wind. It's best to let it spin cause if you put the motor in gear and the prop hits something, such as your driveway while you're going in or out of your yard, there is no give and you could damage your prop or worse, the gears inside.
401.2 without prop
Sure! So will a trolling motor. Maybe not as fast as you'd like, but as long as you keep the prop out of the weeds, you'll move.
To remove the thrust washer from a 1997 Force outboard motor, first ensure the motor is securely tilted and supported. Then, remove the propeller by unscrewing the prop nut and sliding the prop off the shaft. Once the propeller is removed, you can access the thrust washer; gently pry it off the shaft using a flat-head screwdriver or a similar tool, being careful not to damage the surrounding components. If it's stuck, applying a little penetrating oil may help loosen it.
right behind the prop, on the same shaft
For a 1985 Evinrude 9.8 HP outboard motor, the prop nut torque specification is typically around 25-30 foot-pounds. It's essential to ensure the propeller is securely fastened without over-tightening, which can damage the prop or the motor. Always refer to the owner's manual for the most accurate specifications.
The outboard prop does not spin in neutral because the transmission is designed to disengage the propeller from the engine when in that gear. This prevents the prop from rotating while the boat is stationary, allowing for better control and safety. Additionally, it helps to protect the engine and drivetrain from damage when the boat is not in motion. When shifted into forward or reverse, the transmission engages, allowing the prop to spin and propel the boat.
