I troll on Lake Erie with my 300 Verado. My planer boards pull hard. I actually have to bump up rpm on Verado to hit the speed I want.
I wasn't sure if I'd need to add a kicker. Thankfully I didn't.
If I troll without planer boards I have a bucket I throw over each side on a rope. It slows me down enough to have to bump up speed to hit my target speed 1.8-2.2 mph.
Just a data point.
