There is a lot of gear you need to troll,but just starting out I can let you know what I run and has worked well for me.I buy most of my gear from Fish USA but lately some of my orders have been back ordered due to supply chain issues.So don't wait to long to order.I would start out with at least 2 and preferably 4 rods to start.
The Diawa SG27lc reels work well and pair them with Diawa wilderness rods in medium action 8' length.I would spool those reels with Maxima ultragreen 15# test monofiliament.
Get the offshore OR inline planer boards.Buy some #1 black dipsey divers.
If getting some crankbaits start with Bandit in stock colors.Scopion stinger spoons are another popular brand to use too.
Lots of other brands work well too and there are a lot of ways to successfully troll.Good luck with your boat and getting started trolling.
