My father just bought a boat with a 1988 Evinrude 9.9hp on it and we have been having problems getting it started. Engine will start but spits/sputters and stalls after about 10 seconds. Wondering if somebody can explain or, if you have an owners manual, send pics of the starting procedures. It also doesn't help that the decals on the choke, the other knob on the front, and the throttle arm are all worn off, so we have no idea where they need to be in order to successfully start the motor. Any input is appreciated, Thanks!
