Quality boats last for years. (Think G3, Skeeter, Ranger, etc.) Nothing feels as good as fishing out of a boat that is paid for. However, your electronics are likely four to five years old. Depth sounders are like PCs, they age quickly. Think about what you use the most. Your trolling motor and electronics see more hours of use, than anything on the boat.The first upgrade should be your trolling-motor. Minn Kota is the industry leader in quiet, efficient operation. Consider the Terrova and the Fortrex. A friend just purchased one for his 1998 bass boat. He is thoroughly impressed by the power and the lift assist.
Update your electronics. One veteran guide stated, “I’ve learned more about this lake in three months than I have in the past thirty years.” as he pointed at his Humminbird. Enough said.
Protect your investment with a new boat cover. Try the industry leader, Dowco Marine. Visit their website for their “boat finder”. Choose your boat brand and select the model to find the correct cover. Off the shelf, covers are okay. You may be disappointed with the fit. A poor fit will result in ponding of water and leaves. Loose fitting covers will flap when towed.
The often forgotten trailer needs a little TLC. Check tires, rollers and the bearings. New radial tires will improve your gas mileage.
These improvements do not cost, they pay.
