I guess I should also include somemore info. I am looking at buying a boat that has the 70hp on it. The lady told me that is some problem with the wiring and the starter won't turn over. They are trying to get rid of this boat real cheap. Are these motors hard to work on?

Kinda easy to work on but parts are expensive. Look for a way to jumper the starter to get it to BRIEFLY turn over, you will need to put on a water pump first thing since it sounds like it has been sitting. The reason i say crankit over is the starter is a very expensive part. Mine has a solinoid like a ford on it but the newer ones might not have them. It should have electronic ignition in the 80's so it will be reliable. Good luck.
I had a 79 evinrude 70hp, I dont remember ever having to do anything to it. Make sure it hasn't had a rough life in saltwater. There is a sacrificial anode on the foot it is dull metal and should not be corroded to crap. The inlet screen in foot should be intact with no holes in it, The fly wheel should turn by hand and the shifter should work freely. Electric choke should click when key is depressed. I assume the battery is toast so bring one. Lube the Teleflex cable for the steering and make sure the trailer is in good shape, leafs aren't rusted etc. Trailer lights are cheap and have never worked on any boat I have brought home. Buy new lights and grease the bulbs then reinstall. I have own and worked on boats since I was a wee lad. Let me know if you need anything. Instant message fperrick.
