Let me add this to this discussion that's gone off track.

The shape of the hull will make all the difference. A flat bottom dory
will get a much higher speed than a deep v hull. Just look at C-Dorys
and their HP requirements and compare the same to a deep v power boat.

I haven't had the chance to take the boat out for a spin yet. Go
figure. It's been over a week now since I purchased it. The Bayrunner
looks to flatten out quite a bit in the stern and since aluminum is
much lighter than fiberglass or wood I would expect mine to go atleast
15 MPH.

Now consider a 3,500 lbs sailboat with a full lead keel being pushed
around the water with a 9.9 hp at 6 knots. I don't find it that
difficult to believe that the other fellow is getting close to 20 mph
on his aluminum boat that weight probably a 1/3 of the weight.

I'm really itching to take her out for a spin and I do hope this great
weather that we're having in the SF Bay will hold up throught the
weekend.

Borrow a GPS from somebody - that will give you a pretty accurate
reading.

Also
somewhere there is a major power to weight ratio drop. if his 50 does low
30's and it is probably 50 lbs heavier than mine and possibly his motor
shaft is not as deep down as the Suzuki this thing looks at least 3" longer
than my 9.9 long shaft. that gives you better plane and the prop pitch is
different anything is possible.

That's true enough, but the 9.9 claim seems a little, well, odd for
the same reason - power/weight ratio.

Try the GPS thing - that the easiest way to determine speed and
compare it to your speedo.
