Motor question

Hi All,

I have an old Evinrude 35 HP engine. Maybe from the 60's. I just replaced the throttle cable on it as the old one was really stretched out. We tried it last night and after a few small adjustments the boat started hauling pretty good. We had it around 20-22mph, where it should be. Then it eventually settled down to no mare than 15 mph. Everything sounded real good and we tried adjusting again but nothing happened.

Anyone have any thoughts on what COULD have been happening. I know it's a somewhat vague description but any thoughts would be helpful. Thank you in advance.

Did you check to make sure it wasn't over heating & the vent was open on the gas tank?
