    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!

    I have 1200 hrs on my current 454 with no major issues. It does have the enclosed cooling system which extends the life of the motor in saltwater. This is the 3rd motor in the boat since 1979, current motor was installed in 1994. Keep up on the maintenance and that motor will run for years

    I can attest to his boat... I was at the dock when he launched out of glorietta bay yesterday and his motor sounded WAY sweet... sounds like it has a pretty lumpy cam in it at idle... that being said... KEEP up on the maintenance!!! oil, water pump, manifolds and risers and plugs... and ALWAYS flush(with salt away) your motor after every trip in salt water... I generally flush for 5 mins... and if you don't have closed cooling run your rpm's up to 1200... I was told this by the mercruiser service department when I called them for some info... they told me that there are some areas of your system that does not get a lot of water flow at idle so it is needed to run up to 1200 for the most effective flush... if you have closed cooling it is not needed... just flush at idle

    Man 1200hrs!!! That's awesome! It's been all fresh water and will stay that way. I will definitely keep up on the maint. How can you tell when it's time to replace the risers/manifold?

    I wish I had a boat with a BBC. I hear that a lot of women like those. The Kardashians might even want to go for a ride.

    best practice is to take them apart every year and look for pitting and rust in the water passages.. here is some links to give you an idea

    Average conversion from hours to miles is 40 miles to one engine hour. I would bump it up to 60 mile to one engine hour for the harsh marine environment . That being said , you only have 30,000 miles one your Big Block

    A Cole flat bottom with a 454? Now that is is fishing rig.

    That boat is so light a 454 will last a long time like everyone said. Clean fuel, clean oil and quality cooling, both oil and coolant. Watch the drive train components.
