i would think a jet drive would consume way more hp than an outdrive.

It does.

You will have to fill in the hole, no brainer. You will need a 2" transom, glaas and wood, another no brainer. The you will need to find some one with the jig to cut the outdrive hole. once you have that done put in the gimbal. You will need the alignment tool to set the motor, get that and set the motor. The rest is bolt and go. It can be done, just takes time and money. Oh yea, and about 24" of transom higth.

Asking this question in the jet section is like asking about gun control at an NRA meeting. I would say the outdrive section may be a little more receptive tothe idea. I would rather have a Jacuzzi than an outdrive. Too many parts and direction changes.

I like it when I hear folks bitch about how expensive a jet is to operate/maintain... and go the I/O or whacker route....:)sphss

Uhhh... yeah... I/O and whackers are waaaaay cheaper... :)sphss:)sphss:)sphss

Not to mention for drag racing. I/O's just do not like full throttle application from a dead stop. If you already had a jet and wanted to drag race your boat, it doesn't get any better than a jet. :|err

Switching

My first boat was a 21 Spectra 460 jet. I thought a bigger boat would be nice and bought a 26 Sleekcraft 454 with a Merc. TRS and sold the Spectra.

What a BIG MISTAKE!

With the Sleekcraft I had to maintain 5 different fluids like the outdrive, transmission, power steering, hydraulics, and engine oil.
Then theres the thermostat, and don't forget the water pump impeller that can be a sure event in itself to ruin a day or possibly an engine.

The Sleekcraft is gone and another 21 Spectra jet is being rebuilt as I write this.

I am totally sold on the jet drive concept and its simplicity.

And talk about eating up h.p., A prop won't give no where near the holeshot that a jet can, so when your passengers get thrown in their seats from a dead dig ask them who's boat feels faster?

Maybe he is just looking for more time on shore working on this and that? Maybe he wants to be able to send people to the hospital because of the prop? Maybe he wants to go slower? Maybe he wants to be able to tear a gaping hole in the transom when he hits an unmarked shallow object? maybe he is tired of being able to steer at low speed and idle, or being able to whip the boat around in a 20 ft circle to pick up a skiier? Maybe he wants to have to get down to idle in order to go in reverse and then depend on some form of "black box" of relays to disengage the drive then re-engage it in the opposite direction. Maybe he wants to ruin engines when the thermostat sticks cuz boats dont exactly use bottled water to cool the engine unless you have a heat exchanger? Maybe he wants to be able to ruin all the nice flat water for the rest of us? Yep, sounds like there are lots of reasons to go with a mixer or eggbeater to me.

Then again maybe it is because he is tired of having to work on his jet boat so much. I heard from everyone ow much work jet boats were before I bought mine, everyone said it is an hour on the water and three hours working on it. They were so full of bull ******, It is just like your car or truck, yes it requires that little thing called maintence in order to stay running correctly. There are way less parts to wear out in a jet than an I/O or OB, less fluids to change and maintain levels of, the cooling means is 10x more dependable, and the drive is self cooling too. All you have to do is use quality parts and MAINTAIN IT!!! Try rebuilding one I/O drive and you will think a jet drive is a freakin walk in the park!!!

the reason jet boats need to be worked on so much is because jet boat owners are always looking for MORE POWER!!! Grunt grunt :D:D:D

The bummer is, it takes a LOT of power to make a jet boat go. Well, depending on hull too.

My friends prior 21 Liberator/outboard was extremely impressive in how light and efficient the hull was at 40 mph...while my 21 Daytona 468 'jet' is plowing along. :)st
And then he would give his Evinrude a little shot of juice and bust 100 mph easily.:)devil
And how much HP would it take for my 21 Daytona Jet to crack 100 mph :Reality
In short...I would have bought my 21 Daytona if it had a OB, in a New York second!

I would not say 100mph is easy with jet or O/B, It cost less to achive with O/B, but to go faster, I'd have to say jet powered. There are several in our club that are well into the 100's that are jet powered.

From what I have come across, Jacuzzi's are not bad pumps. The take a little work and experimenting.

I swear to you pending Time & Money I will get a Jacuzzi to turn a bill Safely before i die
