I picked up a very clean evinrude 4.5 yesterday from a local yard sale. The gentleman I bought it from said it had been gone through by a marine mechanic 5 years prior and only used once or twice a year since that time - take that for what it's worth. Here's the situation: When I run it in a barrel of water I get water spitting out of the upper exhaust and the engine stays cool, but there is no visible stream of water from a tell-tale hole. I can't even find a tell-tale hole on the motor! I've ordered a new impeller to be safe, but would like to take it out before it gets here. Does this motor have a tell-tale hole?? Should I be concerned at all since I am getting water out the upper exhaust and it is cool?
