I have low hour 1972 Evinrude 9.5hp and when I test compression using the low impact recoil starter it get 62 psi upper and lower. When I use the manual rope start method (not the recoil manual starter), I get about 72 psi upper and lower. I do not use an electric drill to test compression because it gives false high readings.
My understanding is that these motors are low compression motors that were intended to be used for smooth running and low trolling. They were made for fishing and not speed racing….lol.
They are light and easy to store and carry. The negative aspects are mainly the exhaust leak issues that happen after decades of the sealing rubber parts that go bad from time and exposure. Mainly the exhaust housing seal and shift rod boot.
They are nice little motors if serviced well and don’t have exhaust leak issues.
