Hey guys, I know this is a fishing site and I am a avid fisherman.. My family on the other hand loves the lakes/river so I found a cole. It currently has a 1990 454. I'm just looking for some suggestions on how to keep this kitten purring. The motor has 500 hrs all fresh water and we'll taken care of. I've read reviews and talk about these motors and have heard they can go for long time if taken care of properly. I don't want to join some race boat forum to get some insight. Any of you have a older carb'd 454 with higher hours? Let me know, Thanks!
