Hi, a friend of mine has a '05 tr186 with a '12 Mercury Optimax 150hp (standard version, no pro xs).
Boat has 6" hydraulic jack and dual console. My friend tried several setup with different props but his top speed is only 55mph.
I have the same boat with 150 VMax HPDI and my top speed is 64mph: 8" jack and single console.
Could the different outboard and dual console cause 9mph difference in top speed?
My friend's boat had some deep hull scratch before he bought it. Scratch was repaired but some big portion of gel coat had to be replaced. Also the hull was totally repaint. I do believe that this repair, if not properly done, could have cause the top speed lost. Unfortunately we never tried the boat before the repair.
What do you think?
