Is anyone running an outboard jet, on a mercury or tohatsu 30hp or similar? Thinking about doing one on the duck boat for low tidal areas.
Cheers.

Used to rent one out on small boat on Taupo many years ago, was a great little unit, could bury it in the gravel and start it with no ill affects
Thanks, I quite like the idea, not too many around though.
This was just a little two stroke, from memory a tohatsu, gotta say sounds idea for what your going to use it for, we used to hire boats with seagulls on them but were forever putting new drive pins into the prop
Ask here , these guys will know River Jet Boating Forum • View forum - Outboard Jet
call Monty at Southbridge Engineering.He imports and sells them.Top bloke.
Thanks for the info guys. :)
Yep we run a Mercury, it's on a 25 but they call it a 20 because the jet soaks up power compared to a prop outboard. the snail drive jet they use is pretty good at chewing up gravel & stuff, much better than the standard Hamilton type. It'll run up braided gravel type rivers with only a few inches of water under the intake.
Not exactly sure how well it eats weed though?
Great, thanks Mistral, I'm pretty convinced about them, just have to find one for the right price. There's a nice 30hp Yamaha OB Jet on a RIB in trademe now but I don't want the RIB...
Got one of these coming..
Tohatsu 25 Jet
Should be quite good at low tide on the estuary...
That'll be interesting, good plan I think
What are the worth ? If you don't mind me askingQuote:

I'm lucky, this one is new old stock that has been sitting at Tohatsu in Aussie for a few years, no one wanted it. The same 30 horse prop model was NZ$3650, this jet model with the same powerhead was originally over NZ$7000. Im getting it for somewhere in between.;)
It has to be the price that puts people off, I can't think of any other reason not to have one over a prop model.
My jet turned up and I've just finished mounting it. Have to get it over to the dealer so he can finish his checks before sea trials... I brought the big arse bracket back from the states last week, it will enable my to find the sweet spot in terms of height of the intake.

Looks the berries, just rember power on for steering, haha, I don't think you'll be disappointed. That brackets good
Cheers Maca, it's certainly going to be a new experience with a jet. After sea trials, I'm thinking about ditching the two standard fore and aft alloy thwarts and building a modest centre unit like jet ski seating config, a wheel and remotes, under seat stowage etc. I was a bit staggered by the size of the bracket when it turned up at the office from amazon. I had no idea of the size, it weighs 20 lb, but the other great thing is it sets the motor back about 5" so there's more room at the transom.Quote:

It's a tiny tinnie, 3.6m and I want to do a wheel and remotes.
:cool: Looking forward to a performance report.:thumbsup:Quote:

Am I right in thinking you'll rip it off the back of the transom in shallow river braids?
The outboard will kick up like a normal one if it hits something. On a slight Vee hull like mine, they recommended to set the leading edge of the intake slightly above the lowest point of the hull to minimise water resistance.Quote:

I like that idea, a sort of sacrificial skid plate cum anti-cavitation gizmo. Hmmmm :)Quote:

I'm quite astounded at the volume it pumps. Some other watercraft users were giving me some odd looks blasting around the shallows behind Whenuapai, I'm sure they were thinking ":wtfsmilie: that dicks gonna run aground...." I have the jet intake set about 20mm above the keel line and at full tit, it's sitting in a hump of wake about 10" off the transom. Minimum resistance and no cavitation even in tight turns.

Very happy. :beer::beer::beer:
Looking good, my memories were much the same performance wise
