25hp Mercury is Sloooow.

I agree with the above post.
If it's in the budget maybe some type of tach could be installed.(tiny tachs are pretty cheap)
You may not have the right one(prop),which not only makes the boat slower but it's hard on your outboard.

Raise the motor more just watch the the motor is peeing.

I raised the motor so the cav plate is level with the bottom of the boat. Took it to the lake for a trial run with my iPhone speedo app. Messed with the tilt pin to get it to the point where it ran the best. After all that the iPhone read 21mph. Does this sound about right for my boat and motor? Would think it could do a little more. I was expecting mid 20's. I can live with it the way it is now, just wanting to know if I could get more out of it.

A little more information, I looked at the prop, it is a "Power Prop" 13 pitch.
