Big block bottom ends take a very long time to just wear out. Most time bottoms ends are gonna into is through catastrophic failure. Dropping a valve, water ingestion or something along those lines.
I have a friend with a 90 42 Oneanddone on here. Over 600 hrs on stock bottom ends. 454 with blowers. They are basically 525sc clones. Just got new cams and valve trains from Madera. Boat runs like a champ and still has great numbers. Unless you have a low compression check I'd personally roll with bottom ends but stay up on top ends and headers to avoid catastrophic failure.

I'm meeting with my mechanic this week or early next week and will verify compression and a few other tests to give me an idea for what to expect and will keep you all posted.
Have a super night

To be honest, I have no clue. I bought it last year with 280 and put close to 120 hrs on them over the summer. As mentioned in a previous sting, saw the boat on a beach on a Sat, bought it on Mon and it was in my driveway Tuesday......I new very little about boats this size but had no intention losing out on this purchase. I thought the boat was a new boat when I saw it and when I found out it was a 2004 I freaked. The guy I bought it from was a real gentleman with nothing to hide and offered anything I wanted but seriously I was just in awe and did whatever I had to do to get it home and fast lol.......I will ask my mechanic if any work was done on the top ends since he was the guy that serviced the boat for the previous owner. I would love to hear a yes but ya never know. I do know that this thing runs like a dream and at WOT, both engines are exactly at 5200 RPM,,,,,,a very good sign that everything is still hanging on well.

It sound like its time to refresh your motors. But I would take it to Ron Potter at Potter performance. Let him do a compression and bleed down test. he can tell you pretty quick. He also wont tell you something just to talk you into spending money if its not necessary for you. But if it is necessary. He is the best builder out there. Maybe a little more expensive then some but you get what you pay for. Check out my thread on this forum. Its titled 500 EFIs built by Potter Performance. My motors are about to go back in the boat now and its been nothing but a great experience from the start. Also a total quality build all the way threw. My old motors, the tare down and the whole build are on that thread. Look at it and let me know what you think. If you have any more question ask away or PM me and I'll help you as much as possible.

Thanks Barry glad to have you on here. I take VERY good care of my 525 Fountain and if it ever sees saltwater I take it to a lake that afternoon or next day to run it out in a lake! Plus dunk the trailer real good which is really the only effective way to rinse the brakes. With that method I have no saltwater signs on either the boat or the trailer and the brakes are original. We have a lake house so it helps! Be sure to change the oil every 20-25 hrs or seasonally which ever comes first. I have always used Merc 25W-40.
Question, what engine coolant do you use? I use the orangs one I think its by Merc but not the diuted product, its the heavy or dark orange one....just curious, never asked that before.
As for salt water runs, My boat has never seen salt and since none of that exists near me, I'm safe however if I ever pull it to salt water, rest assured, boat and trailer would get a serious rince. Nothing worse than salt water and trailer brakes....i've read many expesive mistakes about that one!
I believe 25W 40 it the viscosity I use...have to doube check but it sounds right.
We shall chat soon buddy ave a super weekend!
