Just looking for opinions here...
I have twin F250's manufactured in July 2005.
I continue to be amazed with these engines. They have been trouble free for duration I owned them.
I bought my Grady-White 330 Express ten years ago. F250's had 312 hours on them. Today, I just exceeded 2,100 hours.
15 years pumping saltwater through them in a marine environment. All I can say is they are INCREDIBLE engines!
Here is my maintenance program over the past 10 years:
- Very rarely do I run them over 5,000 RPM's (<2%). I cruise at 4,400 RPM's (say 30% of hours) and it's 1K RPM's or idle after that (about 70%).
- Oil changed every 75 hours & Oil Filters changed every 150 hours (I do filters every other oil change - kinda hard and messy to do...).
- Fuel filters changed annually and I always add Ring Free at 1 ounce per 10 gallons of gas.
- New Water Pumps every 300 hours (average). I run in clean, deep, ocean water (no sand or grit).
- VST's cleaned about every 1K hours and fuel injectors cleaned once in past 10 years.
- Timing belt changed at 1K hours. Not sure if I will do it again as the old belt looked perfect after removal.
- T-Stats cleaned or replaced every 300 hours.
- Freshwater flushed upon return to the dock (while engines still hot) for a minimum of 10 minutes per engine.
- Spark plugs replaced every 3 years.
- LU Gear Oil changed every 100 to 120 hours (gear oil always coming out clear)
- Boat is lift stored so engines are out of the water 95% of the time. I change zincs when needed (about every other year).
- 3 years ago, I had the Mid Section Manifolds removed and replaced as a precaution to the dreaded corrosion issue (no corrosion noted BTW).
- New Motor mounts and Power Trim seals replaced while the engines were off (above)
- I currently put about 300 hours per year on these engines.
So, now, I am at over 2,100 hours and counting.
The mid sections are effectively "new" and everything else running perfect (hope I didn't just jinx myself!).
These engines have effectively NO Market Value and I plan to use them until they experience a major failure.
Kinda like driving a high mileage car... If it ain't broke, don't fix it...
Given my maintenance program and 300 hours per year - How much longer do you think I can go until I need to re-power?
Curious as to your opinion. Thanks.
