"Hi all!
I've seen many posts about jet drives and would like to know the benefit of this system.
I understand that it all boils down to the terrain of where the boat will be used, yet the jet drives seem to be scarce. I've yet to see one on a boat in my area. I'm mostly in fresh water.
How would you change performance of a jet drive? On a prop motor, you'd go for a different pitch. Can a jet's pitch (pump) be changed?
How is the fuel consumption (assuming same conditions and rig) of jet vs prop?
Maitainance of jet drives costly vs prop? Spares availabilty?
Do they also cavitate?
Does HP output rating stay the same if I swapped my prop for a jet drive? I have a 1997 Mariner 115 ELPTO with 17" prop, what jet would I look at? I have a 18,5' bowrider that is used in fresh water, mostly cruising, seldom skiing or tubing. The performance is good, just looking at other options...
Should I consider this option?
Thanks!
Benjamin."
