Reply To: Evinrude 7.5 hp – Hard to pull

[aquasonic]

The 54′ and 55′ Evinrude Fleetwins have the Simplex Starter and are just plain hard to pull, even when everything is set up correctly. If your motor has the original brown wire core starter cord, then there is virtually no stretch, and that makes it a little tougher on the shoulder. Nylon cord stretches a little, and is a little bit easier on the shoulder.

In 1956 OMC came out with with the Eas-a-Matic Starter. That is the elliptical shaped spool that has “cam action” and makes starting these motors much easier. They also have a larger pulley that requires more rope per revolution of the flywheel. The amount of work required for one flywheel revolution is fixed. If work is defined as force x distance, the more rope length per flywheel revolution, the less force is required.

So check out a 1956 or later 7.5 and see if that works with your shoulder situation.
