We spend tens of thousands of dollars for our boats and a truck to pull them, huge amounts of money for the electronics to navigate the boat and find the fish, 100's of dollars a year for the gas, much more for the yearly insurance, then boat ramp fees every week and a small fortune for our tackle and who knows what other expenses.
The amount of money to maintain a 4 stroke motor over the course of a year, compared to all the other expenses we have, is so small it's hardly even worth talking about.
