Just got done looking at a 1975 Evinrude 70HP. Engine was clean for the year. Had good spark. Ran good off of a hose and peed water right away. I wasn't able to take it for a lake test though. Power Tilt and trim worked good also. No signs of leaks on the lower unit. Compression tested at 105, 110, 110. Not sure if my compression tester is the best, but the readings are pretty close at least. The person is asking $500 for the motor and controls. Does this seem like a good buy or not? Also, I was told that the water pump was just replaced this year.
