Hey Lee; thanks, I was just curious for the most part.Great thread magicalbill started,
I suppose I do not have to push my engine like the rest of you sea bearing sailors, but I like to cruise at 4000-4200RPM. I am frugal when it comes to fuel burn.
Thanks for you that said you will push the envelope to get rid of carbon.
A final thought on this, you mostly have Yammies, and I have a Honda. The Coast Guard use Honda's and pretty comfortable saying they push them hard at time and get 5000-6000 hours from the engines, so I think the new generation of engines have hiccups here and there, but they in general can take a beating for a long time.
My Grady Club had several 330's with F250's and they have to be spun above 4700 to run 30 MPH. That's underpowered to me, but it makes a strong case for long life even with hi RPM use, as many of those 250's clear 1000-1200 hrs and haven't even hiccupped.
As mentioned, I'm more conservative with my revs, and I just wanted to see what everyone else was doing.
Mr_mbuna has an interesting point, as I have 350's on my Marlin. Running them at 4300 keeps them out of flywheel degradation range. I usually can't run that setting as 4300 puts me at 39-40MPH and I seldom have a calm enough sea state for that speed. I also concur that above 4500, your really burning fuel. Above 5000 RPM I would suggest looking anywhere else but the fuel flow info.
Thanks again for all the input!
