Has anyone used the pro troller smart tabs yet. I presently am considering upgrading to a 50hp Honda tiller from my present 30 hp Honda tiller on my Crestliner 1640 Nighthawk. I love the motor but I'm a bit underpowered. I have a 17 gallon built in gas tank. Boat tends to be bow heavy and I can reach appox 23mph by myself on a flat lake with half a tank. Put another person, more gas and gear and I'm lucky to get 15mph. Boat is 640lbs dry weight, 75inch beam, 16feet 4 inches long. I presently troll down to 1.7mph with the 30hp. I anticipate the 50hp would likely put me 2.4mph or higher trolling, which is too fast for me. I don't like trolling plates and I would rather avoid drift bags. Does any one have a general guideline as far as how much the protroller may cut trolling speed.? Literature says up to 35%. Does anyone have experience with before and after trolling speeds with their motor. I would rather spend the money on smart tabs protroller than changing props and using bags or plates. But I do know I won't have room for a kicker and keeping the trolling speed down where I am under 2.0 mph is critical. Any advice appreciated.
