    Joe Reeves timing on 70hp

    (1976) Had a question or two on the timing procedure. It says to put it at full throttle AND move timer base to rubber stopper. Then crank over and set 4 degrees less than spec.

    Joe Reeves WOT timing procedure....

    Does my 1976, 70HP Evinrude have the Fast Start feature? I don't see it talked about in the service manual...Maybe only talked about in the owners manual which I don't have?

    Rectifier, stator, amp guage and timing

    Hi guys, I finally tank tested my newly purchased 1976, 70HP. It ran good with pee-hole mod installed. Problem is...only the temp guage worked and I am fairly sure the other guages are wired correctly....The Tach and Amp guage had no response. The Tach guage may be bad but I doubt if both...
