3000rpm or less for engine longevity and fuel.

So I guess I am really babying my boat at 3000 rpm's. It looks like it's not too uncommon to run 'em near 4k.

3800 to 4000 rpms is [email protected] zero boost and a real nice cruise rpm, engines are set @ 6400 rpm red line.
86gps with 1.24 ratio drives spinning 34p x 17.5's and low 90s running our 35p X 17.5 Merc Cleavers.

Your engines will last forever if you run them 3000 or less most of the time. Over 3000 hours on my last one without any major repairs/rebuilds. Sometimes this is just not possible, depends on the rig.
