Thread: Jetboat - someone spend my money

The pumps are rubbish spanners . The motors are great , but they lack the durability and life span that the bigger auto engines have.

Kiwi jameses boat ???

If thats realy what you think you want , but even new they struggled too hook up and i saw the blade fly too bits on an aquatrax last year . Its normal for 6 inch pumps too eat themselves when the going gets tuff , and the harder they rev the faster they puke.
little boats are cool if you already have a propper one !!!

Subjectively...the pumps arnt all tarred with the he same brush.
Yes - there are some junk.. However 6" 10 vane stainless stators don't wear At all, and the ally bronze ones are very resilient.

Not uncommon to see 400+ hrs on the NAs with ECU data showing 50% rpm use above 5000rpm.
supercharged will do the same with the required interval maintainance.
I know of as many failures from them being used infront of Scott 612s that have fallen apart, to actual witnessed engine component failures.
I do ALOT of work with them hence a bias obviously.

It makes little sense to me to put 200, 300?kg of engine and pump into a 12-13 ft boat. As said prior by someone, all adds to draft ultimately.
Majority of car engines underperform comparatively, are heavy and less fuel efficient. Why not evolve into the 2000s a bit?

Has to be others that agree with me as there are a bunch of ski engine specifics in production and getting developed - nozzles, intakes, reverse buckets, sand traps, complete jetunits..
