That's why it's a range..... 4600 lean and mean 4200 with the whole fam
damily.

But assume 4600 is max at leanest config, so if you prop it lighter, watch
the tach and don't exceed.

I just re-proped my boat -- my range is supposed to be 4200-4600

is this under "best case" conditions? (flat water, no wind, light load,
trim
optimised, etc)

Or "no mater what, when you're "WOT" your engine should be between
4200-4600?

Thanks
