Changing Props To Jet--any Remarks?

[signum]

For some time now i'm thinking if i could find the way to change the propellers system to a jet system on my outboard motors....(2x225HP)
I would like to hear your remarks on that subject...is it worthy?

Its a no go I think.

Mercury did a 60hp jet outboard but its was different from the 60hp prop version in a number of ways. It certainly wasn't like you could just change the gearboxes.

I saw a Mariner at Fairweather once, that was a 60 I think. They had dropped off the Gearbox and replaced it with a Jet unit. I don't ever remember Lee being that fond of it though. A failed experiment one thinks. I was up for sale about a year ago.

Johnson/Evinrude did a jet drive unit that bolted on in place of the bottom gearbox assembly.

The OMC workshop manual I have kicking around for 150 and 175HP 60deg loop V engines shows it in detail and has a full strip down etc.

The manual dates from the late 80's or early 90's, I presume they must still be out there somewhere secondhand or old stock, but might take some finding.

Be interested to know some more just out of curiosity.

This company offer jet units for most outboards.

Unless you have a desperate need to operate in amongst swimmers don't bother - outboards are high revving which will cause probs - if you really want jets get a boat with a diesel inboard engine and a proper jet drive.

Yamaha also made / make one - retro fitting a one off gearbox / drive system to an existing outboard would be an enormous job, so unless the link above offers you a bolt on part I wouldn't even think about it - if they were a good solution then they would be more common! Better off converting to an inboard as already suggested - nothing better than a supercharged V8 with dry exhausts and a Berkely jet!

Yes, I have a small job for you. Would you mind taking a trip to Santorini and "roughing up" a certain Manos Catspiss? Payment can be made on flexible terms.

Your horsepower will take a nose dive and fuel consumption will go up with an OB jet. I believe this is a similar when an inboard diesel is coupled to an outdrive leg type thingy or a jet unit.
