36.5 I think,but it gets there instantly!I should prop it up bit but its a handful at that speed.The boat is rated for 15HP or so and the motor is prolly around 120 hp.You lose about 1/3 of the HP by using jet power but its still a wee bit overpowered.We do have a much more powerful motor to put in it but have sorta lost interest after it actually floated and ran.
