Was heading out tonight, had a weird issue w my electronics so we were at idle for about 1/4 mile. Decided to figure it out later and went to throttle up, she shook for a second or two (bogged down) and that was it. I am at a loss. She will start but only for a few seconds, run rough and off. I have fuel in the boat, just put new batteries in which fixed the electrical issue. This is a new to me motor, I have put about 50 hours on her this season and never a hiccup. Any trouble shooting tips would be greatly appreciated.
