Check and clean carbs. If same problem persists rebuild or change full pump. Firstly ensure clean plugs,and fuel filter. If you hook up a inline fuel pressure gauge, then run. You may have low press output, at cont full load. If so you need to open your vapor separator tank. Check and clean high presure pump and pre filter. You need to clean and inspect needle and seat. Than repeat test as outlned above.

I think there is a nut holding the prop to the shaft and there might be a shear pin going through the prop and shaft. Remove those to get the prop off. It may have been on so long, there might be rust and other junk holding it on. Spray with penetrating oil and let sit to loosen the rust.

I suggest you go to this site and obtain a manual for your Evinrude engine. Hope it helps:

In demo mode, it will show fish and bottom details when the transponder is out of water. If the boat is in a mooring, put a metal spade under the transponder, you should see the detail change.
