I have a 1968-1970 Johnson 55 horsepower. I am wondering how I determine the proper pitch and size of the propeller to best fit my engine?

Re: Prop Johnson 55

If you read the stickies at the top of the page and the helps on the prop store page
it will help you understand prop selection better.
If there is a prop on it you need to make a couple of runs with one aboard
give us the prop size and your present max rpm and speed.
Motor came with a 13 1/4 X 17 but final size would depend on the application.
Your prop size should be near the base of the blades or under the prop nut.
Your final prop selection will depend on your typical load and activities.
If no prop we will need the details on your boat and typical load.
