She probably won't troll very well being that big. I know 50hp doesn't seem that big in today's boating world, but for trolling...it is.
She's loading up on the plugs at idle for long periods of time. You can make a few passes then open it up across the lake for a lap or two if you need to troll with that motor.
If it were me... I'd get an electric for the bow or stern and use that. It will save wear and tear on your motor, and be a lot quiter.
