What's your opinion & why on water pump replacement parts?

Since my kicker gets the constant workout I do oil changes 2 times in the season with a possible 3rd time depending hours of operation. The main gets it at 50hrs which doesn’t stack up the hours like the kicker. I mounted small hour meters that track engine run time on both motors. These meters can be found on Amazon at a low price as $10.
