Estimate of Motor Life for Buddy Branch Setup

[Cara.Vera]

Looking to get a rough estimate of motor life on a buddy branch rig. I'm running a 540 on a lightweight hull, mostly dry ground and marsh work with occasional deep runs, the motor has been good so far, but I'm trying to plan ahead a bit, by the way, what kind of hours people are getting before needing major work or a full rebuild.
I know it depends on how it's run and maintained, but if you've got a buddy branch setup or something close, I'd appreciate hearing what kind of life you've seen out of yours.Thanks

@Cara.Vera for a 540 pushing hard in marsh/dry ground, you're looking at a general rebuild ballpark of 800-1500 hours.

It all hinges on things like
RPMs: How hard you run it consistently.
Cooling: Keeping that big block cool.
Maintenance: Super regular oil changes are key.
To truly know, pay attention to power drop, oil consumption, and definitely do regular compression tests!

I second what @MustrdMan said.
I know a few folks in similar situations pushing even beyond 1,500 hours before they considered a major overhaul!!
But I personally wouldn't suggest stretching too much.
Anyway, consistent maintenance, like oil changes and checking clearances, goes a long way.
Those occasional deep runs are fine, but minimizing prolonged high-RPM operation in deep water will definitely stretch that motor's life even further!!

That's all good advice. 800 to 1500 hours seems right for rebuilding a 540 used like that. I agree that keeping up with maintenance, checking the oil and compression, and not running it too hard in deep water will really help the engine last. Smart move to watch for those early warning signs

If you're pushing a 540 hard on dry ground, don't expect 1,000+ hours like it's a marine cruiser. Most guys won't admit it, but real-world rebuilds often come by 400–600 hours, tops
