I did a leakdown on my motors coming out of my boat...it's been all downhill since then.
Guess how many hours are on these bearings?

They look like they have 300+ hours on them, I freshen my blown 540 every 120 or so hours and they have always looked like new (h series running on a 4340 crank that is permatoughed ) running about .0028-.003 main and .0033-.0035 main or so clearence, Smitty
