I have a 2009 tracker grizzly 1448 with a Suzuki 15hp. With just me alone I have had the boat up to 25 mph. With a fishing partner it will not even plane out. I have added a hydrofoil and it didn't do a thing. The boat calls for a long shaft but the cavitation plate sits about an inch and a half below the hull. Im thinking I may need a jack plate to get the boat on plane with more weight in it. I have had the boat up to 21 mph with with 2 people if it ever planes out. I just can't settle for not planing out the boat with a lil extra weight . Any suggestions? Prop,weight distribution? Any help would be greatly appreciated. I've ran out of options besides a jack plate
