How to adjust Trim Tab fin on outboard motor - (boat leans to one side)

We noticed our MAKO 1801 leaned left at high speeds. We adjusted the trim tab fin on the 2006 Mercury 115 outboard hoping it’s the fix.. Equipment used Mako 1801 Bay Boat, Minn Kota Terrova Troller, Garmin 93SV w/ Livescope, Lowrance HDS units. ACC Crappie Stix, Denali, and Bone Head Tackle Rods, Bass Pro Mini spin cast reels with 6lb Mad Braided line, various colored plastic/hand tied jigs. Thanks for watching, for your support, and hope you enjoyed.. Crappie Cats Baby! “I own the rights to this song and music in this video..”
