You might get 40 with stk zen. They r about 200 but u will need a tune pipe as well. Speed cost

In boat motors big torque at lower rpm does not create speed, only handling issues []
To make boats go fast and handle well, smaller props at Higher rpm work best !

This is why RC boats of old like those using homelites etc were never very fast. Simply swapping out engine to a higher rpm Zenoah type motor typically had 10 mph gains in speed.

Look at spending between $400-$500 on motor and pipe for either a stock Zen or Rcmk($80 more +2 xtra HP).
