Howdy fellow boat lovers! I am trying to find your feelings of quality and durability re John Deer Series 400 Turbo... less than a decade old and with fewer than 800 hours. Are these Deer's sleeved and do they appreciate steady, low RPM (800 to 1,200 RPM) for long periods? What's the avg hour of gentle usage before refurbishment? Anything else you can add is also appreciated! - Thanks, W.
