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
Davie

So my new 21" pitch -- me alone, WOT , semi-flat water trimed right, 4300 RPM --
the prop is no good? Too much strain on the engine?

(I may have 14.5x21" prop for sale soon)

You will know after you try it with a few people on board. If you struggle
to get on plane or can't get the RPM's up over about 4000, then you are
over-proped for that load.

If it were me I would drop to a 19 or 20. The prop you have would be
good if you always went out by yourself and cruised, but I would want
something must closer to the top of the range under those conditions
so that when you have a couple people or want to get that skier ot
tuber up you can do it. If your current 21 is an aluminum, a stainless
21 might be the ticket. Just an opinion, not an expert.

Thanks -- I can't afford a SS right now - but I do have a 19" for skiers, it
takes almost no time to swap props.
