Lets see some pics !

What prop are you running on that 120 ?

Highly recommend a 14 1/4 x 19 for best performance.

It is what is!. My 3.0LX tops out @45mph in best possible conditions (clean hull, smooth water and 4 passengers) w/ the 141/4x19 alpha1gen11 on my 17.5 Sea Ray. Don't mess w/ reliability.
