I am surprised that, even after years of participation in this
newsgroup, you haven't learned much of anything about boats and boating.
Do you listen to anyone besides Harry KKKrause?
I am growing weary of giving you "one last chance(s)" to shape up."




I think you are "full of ****e", Stinky.
We were boating at Grand Lake last week when I noticed two guys preparing their Lowe bowrider for the road after morning fishing. It was the same size as my boat. 16.5 feet so I. Went over for a looksee. He had the regular Mercury 60....foot and propeller looked tiny compared to mine. He complained that it took him too long to get up on plane with his right. I have no complaints with mine.


I hope you had a Grand time.
Do you know what "getting on plane means"? Have you ever done it? What
size prop was he running? What size prop are you running? Are you both
deep V or modified V or flat bottom? Are they similar weight? What is
the recommended WOT RPM for your boat? What is your actual WOT RPM?
I realize that you can't answer any of those questions so you'll
probably respond with your usual not so smart ass lame response.

It is certainly not for "performance" as much as giving a good push at
a relatively lower speed.
Yamaha must only make workboat motors tho. My F70 is swinging the
exact same prop as my big foot used and that is the only lower they
sell.
Alternately you could argue that at 60-70 HP, you should be in the
larger prop. The difference between my F70 and Don's 60 are minimal
and 3-4 HP at most. That is from a little better breathing on the
intake side. You will only see that at WOT. I have about 0.3 hours at
anything even close to that.


Your boat fits nicely in the workboat catagory. Proper prop size is
whatever allows your engine to attain WOT mfg. suggested RPM. Your prop
is probably larger in diameter and shallow pitch. Probably 12 pitch.

It goes a little deeper than just matching RPM to prop diameter and
pitch.
High performance boats want the exact opposite of "big foot". They
have as small a gearcase as possible to reduce drag but they are
easier to break and low speed performance suffers.

OK Work boat ;-)

BTW 14x11

It still comes down to WOT RPM. What do you mean by low speed
performance? Isn't that something that matters to work boats more than
recreational or high performance boats. Hole shot is the only thing I
can think of that might interest some recreational boaters.

Low speed performance just means maneuverability, particularly when
you have wind and current. That might be a work boat situation or just
trying to get to the dock at a crowded restaurant.
Swinging that big prop allows pretty big steering inputs at fairly low
RPMs.
I shortened the steering arm on my motor so it turns farther than
Yamaha or Mercury had in mind. I can do some pretty tight turns in
close quarters.
