Using the jack plate, trim tabs and outboard trim together can maximize the performance. To give you an idea, let’s return to the technique of accelerating in shallow water.
Put the trim tabs down, the jack plate up and the outboard trimmed in. Now throttle up. As the boat climbs out of the hole, start lowering the jack plate, raise the tabs and trim the engine out. Then, with the boat on plane, continue to apply throttle and trim to build speed. You also might raise the outboard with the jack plate to reduce drag and boost speed even further. Finally, redeploy the trim tabs a tad to control porpoising.
Each boat responds differently to tabs, engine height and outboard trim, according to Barker. “It’s really a matter of getting some seat time and using these features,” he says. “That’s how you learn.”
