water jets, suitable for shallow river ops

Hi,
Am a new member- would like to interact with someone knowledgeable and experienced with water jets, suitable for shallow river ops.
My location is in the north of India on the river Ganga.

I know nothing about water jets, but I welcome you to the forum.

 

What are you really wanting to know ??
what kind of boat you waht to use it in ???
how big???
what size motor???
petrol or diesel ???
just one unit or two???
how shallow you wanting to use it ???
What kind of speed you wanting ???
how much weight you want to carry ???

 

Water Jets can be used for shallow water, but you will have to figure out how the inlet stays clear from plants and stuff

 

Has a grill over the water intake !!
water jets were made for boats to travel over shallow water and over sand banks and logs and rocks !!

 

Yes waterjets can be used down to very low water depth. See here as an example:

Yes, but if you constantly have to clean the grill, you'lle wont get far, nice video btw

 

How long have jet boats been in existance ?? do you know ?? where did the come from ? who invented them ?

 

Since 1954 at least. http://en.wikipedia.org/wiki/Bill_Hamilton_(engineer)

"I do not claim to have invented marine jet propulsion. The honour belongs to a gentleman named Archimedes, who lived some years ago."

"He investigated the American Hanley Hydro-Jet, a model which drew in water and fired it out through a steerable nozzle underneath the boat. Even when further adapted it did not work well. An employee suggested to have the nozzle just above the waterline."

During the time the jet was being discovered i was just a kid with bare feet and short pants and we lived close to a river .
I was priviledged to have ridden in one of the very first jet boats . It was plywood hull a ford mercury flat head vee 8 and a hamilton jet the boat was owned by mr Bill Dippy who in later years was to be come one of the top jet boat driver in the whole of new zealand , we went up the whakatane in just 4 inchs of water and turned and came back down and nosed up onto the bank so all us kids could get out . yes about 1954 !! i have a couple of picture that my mum took but could take some finding !!

 

Sorry Kapil, I don't know a lot about water jets other than they are expensive and can be problematic.

I'd go with an airboat if it's feasible for you.

Hey guys

Really keen to find some parts (housings) or complete units for two of these beasties !!

 

Welcome, Delta Taupo.

 

I've been to india, and i highly recomended waterjet, since the river has a plenty of sand banks, logs, plastic bags, and rocks with wildly varied depth. But still, not every river in india is the same, so you must be more specific in your requirement
