ok, I'm confused, when I first start out and give the boat throttle the bow comes up really high and the boat does not appear to go really fast, when I trim the motor the bow drops and the speed picks up without any additional throttle input. I thought the bow up attitude of the boat was desirable for faster speed??
Here goes the loaded question, I need a new prop, the aluminum one that I have is pretty beat up (it has clearly lost many rock battles with the, ahem, prior owner at the helm, I've only taken it out twice).
The literature I was able to download shows:
1) o.e.m. prop is aluminum 13.75 X 21`
2) Alpha 1 outdrive 1.84 : 1 ratio,
3) Mercruiser 4.3litre V6 I'm guessing 160hp version (there was a 180hp version)
4) 4400 - 4800 rpm WOT, she can reach WOT RPM range according to the Faria Tach
5) speed according to Faria Speedo (Garmin verified) was only approx. 36mph.
6) boat length 20' 2"
7) Beam 7' 7"
8) Dry weight 2350 lbs
9) fuel capacity 27gallons ( it was full)
10) deadrise 15`
11) 1 full size male 1 full size female
I am looking for overall performance
Mercruiser website says 14 X 23`Vengence but that website only list boats from 2000 and newer, so it may be "off"
Any input would be appreciated!!

What I learned: even if the dock is lined with tires, one should still use bumpers, I almost lost my SeaRay emblem and I also have to spend time buffing black tire scuff marks off of her argh!!!!!
