I am contemplating a Lund Classic Sport 1775 (17' aluminum deep V walk thru, about 1100 pounds) and wonder how slow I can expect to troll with a Merc 90 4-cycle motor? Are there any websites with trolling tests or specs for speed, gas mileage, etc? Lotta talk on the manufacturer's sites, but not all the info I need to make an informed decision. I know there are several reasons to get a kicker (backup power, less wear on the main motor, better speed control, etc), but I may do without a kicker for a while. I do not enjoy the trolling plate on my current rig or the noise/smoke from the 2 cycle. Trolling bags aren't exactly my cup of tea either. Any input apprciated.
