Bass boat questions
I'm not trying to cut down your boat, but be sure of what you have before dumping a bunch of money into it.
Jackplates and high performance props may get you 2-3 mph. It cost a lot of money to go a little faster in a bass boat. Our lakes here in the north don't really warrant the cost of the added speed. I always try to prop my boats for a quick hole shot, because I'm only going to run for a mile or two.
Spend the money on fishing equipment that will help you catch fish, not go faster. Just some advise from someone who has been there and done that.
