So I have a 1985 Evinrude 3 Cylinder 70hp. We were out on the lake last weekend, and any time I opened up the throttle for more than a few seconds it would begin to miss, cough, and sputter. Pulling the throttle back would help, but didn't solve the problem. As the day wore on it no longer mattered what speed the motor was run at. We put it on the trailer and brought it home, and I believe I've narrowed it down to the Fuel Pump being faulty. This particular motor was one of those original VRO motors, and at some point prior to me the VRO fuel pump was removed and replaced with a generic one. The issue I have is that I don't know what part number to replace it with that will give me the fuel flow I need, and there's no part numbers on the casing, so I can safely assume it's a cheapo from Amazon or something. Insights would be great. The existing one has three connections, and is laying loose in the engine case, not mounted to anything. Thanks.
