Two trips ago the aluminum prop hit something and the engine died and a piece of one of the blades broke off. I replaced the prop with the same pitch and size but this time I went with a stainless prop. The next trip which was 2 weeks later everything seemed alright the engine ran good. After multiple runs to different fishing places the engine all of sudden wouldn?t run at wide open speeds, it would die out. The engine would start back up but seem to run a little rough. I was only able to run at a no wake speed. I checked fuel filter to see if it was clogged but it wasn?t.
