at its time, was this a good motor or did it fall off the dependable johnson shelf?<br />am looking at 75 to 100 hp motor for the T166, and was wanting to keep it of the same era.<br />-<br /> but if the 78 to 82 j/e had problems- ill go newer.<br /> would like something that is easy to work on, but yet dependable.

That's the standard Evinrude/Johnson V4, which was a pretty good motor. Watch the thermostats - they stick on those & are a bear to change. When the motor's fully warmed-up you should be able to rest your fingers on the cylinders for a couple seconds, but it should be HOT (around 140 degrees F). Good luck!

Really depends on what shape this particular motor is in. They made a virtually identical motor, as the 88SPL and then 90SPL, up until I think 1998, so buying newer won't necessarily get you a better design. 1978 was the first year for that series of V4 (dual powerpacks, dual thermostats, all-mechanical LU, etc.).
