compression on 1991 Evinrude 70 HP

[joetheis]

Bought a 1991 Grumman 18' boat with a 70 Evinrude 2 smoker outboard hanging off it.
Once I pick her up, I can get serial # off everything and get a service manual and parts manual.
I was just wondering what kinda compression I should have in that motor??
Thanks!

I have a terrible case of boat envy! Your boat is always nicer than mine!!

You should have 110 psi or better.
You'll need about 90 psi to make things hum...

Great!
I got the boat to my place at Clayton. Didn't have time to play with it, as my truck hauling my old boat died and I had a C.F. getting old boat towed as well as truck towed to a garage.
I ordered a shop and parts manual off Ebay, so I'm good to go!
