Top speed :)

Me and my buddy who just got his 98 175 Tracker with 2000 Mercury 50hp raced today.
The day before I was with him and we clocked 31.7 gps trimmed up as high as it would go.

??x14 prop
I have the a 1990 Spectrum with a 1990 Suzuki DT40
And I was creeping on him to end probley 2mph more.
We both had 2 people, his 2 people were lighter than myne. I believe I have more tackle on board also.

I cant wait to get my 11-3/4x 17 prop : )

What do you guys think Ill top out at with that?

If your running at 5500 rpm's & your lower unit is 2.25 to 1 I'd say about 37mph

I still say you need a tach
Hard to play much with prop pitches without one,especially as much as your going to try.
I have the same size boat only lighter,same motor.I was running a 13 pitch at one time and still in the proper rpms(upper end).I may be wrong but I think your rpms will be to low....maybe by yourself with no gear.
Good luck.
