Mercury outboard question

Thanks Troy, 25 years!?!? Wow. I've "heard/read" impeller should be changed every other year.
No signs of issue with mine, just preventive maint. While doing degrading maint on back lol.
Great news Steve. Hopefully everything is straightened out........LOL, I have the original water pump in my 1996 Honda BF8 kicker that I have owned for 25 years. It just keeps ticking. I bought all of the seals and impeller kit 20 years ago with good intentions........
