Will an I/O produce more power than a jet motor with the same amount of horsepower?

Question

I have a jet ski with 155 hp and am looking to get an I/O bow rider and want to have enough power to pull me up on a wakeboard and I weigh about 240 lbs and the jet ski struggles so I want to know if a 4.3 liter with 190 hp will get the job done with more ease. Thank you for your time.

Answer 1

It will, a prop is more efficient then a jet, the engine has more hp (190 vs 155) and has much more torque then the 155.

Answer 2

that will work plus if you had to you can change the prop for more whole shot

Answer 3

Any boat or craft with the same horsepower and same thrust power applied using a prop will always be more efficient than a impeller system used by a personal watercraft or jet boat.

You can ask your local marine mechanic, dealership, or a boater/PWC user with a lot of years of experience.  They should say the same thing.

Be careful of changing the prop's pitch as it can cause your inboard/outboard to either bog down due to excessive load per rotation or over rev (too high RPM) due to not enough load per rotation.  Research your choice before changing to a prop with a different pitch.
