Well after a few weeks of testing the Optimax 135 was quicker.
Suzuki 140: 40.1knts
Mariner 135 Optimax: 43.9knts
Also the acceleration of the opti was amazing!, 0-20knts in 3.4 seconds.
Suzuki 0-20knts in 5.8 seconds
And very suprisingly the 115 optimax was only 2 knts behind the Suzuki.
The Test boat was a Rigid Raider by the way!!!
