Finally got her out this weekend with the datalogger, I'm impressed!! Aside from the impressive launch like the Bean boat, cruise and WOT top end is yielding an average 3 more mph with the same fuel flow as it did with the 212 with the same load. It is turning more RPM than it did with the 212, 3300 for 30 mph cruise and 4550 WOT at 50 mph GPS. I will swap to the smaller nozzle insert and compare in a couple weeks.

And no cavitation or blow outs, just a 4800 rpm flare which subsides in a boat length :)

Hey Jeff
Do you know anything about somebody having issues with breaking the buckets on the new pump? Isolated incident, bad casting for the bucket, any ideas? We're looking to have a boat built and I'd really like to go with the Scott. Thanks for any info.

Hi Chris ,

Yes we did have one bucket that the customer claims failed ' just like that" . It has been a one off incident . We are not sure as to the cause as the customer has yet to return the broken one for us to inspect so we are questioning the " just like that " statement until we see the broken bucket in person. That being said any possible scenario's that could have lead to any possible flaws in the bucket casting have been addressed on our part to insure that the possibility of that happening again has been eliminated .

Thanks Jeff
I'll give you a call tomorrow. I've got a couple other questions for too about the 912.

NO SLIP by JBNZ Jet Magazine

Postby Scottwaterjet » Sun Sep 23, 2018 2:22 pm

A recent article by Paul Mullan in the Jet Boat New Zealand "JET" Magazine.

"After just 40 hours from new Ryan swapped units and reckons he's transformed his family boat. Absolutely no slip off the mark, or in turbulent water. In fact, nothing Ryan did to that boat in the fifteen minutes we spent in the rapid would make it slip. Into the current, with the current, side on, it just wouldn't let go. He'd just stand on the gas wherever he was to try to get it to 'break' and it wouldn't."

Full article attached. Enjoy. And thank you to Jet Boat New Zealand JET Magazine for allowing us to post this article. The JET Magazine is a great read.

That's funny, article and photo both say LSA, when it's clearly a Raptor 575....

After hearing Ryan's story I decided I had to have one!! Our build hasn't even started yet but I've got one with my name on it.
Thanks Jeff!! :Drink:

You'll love it! My tightened & pitched 212 had a "stupid" amount of slip to it, enough to boil the pump to 6500 rpm with no boat movement if stabbed to WOT...not any more :-) Since then I upgraded the throttle body from 1000 cfm to 1500, yielding another 200 rpm WOT and flare RPM, but the 912 still holds on like a charm.

At what horsepower does the 912 become the better fit than the 852?

I think it is more boat and load weight. I am stuffing lots of HP into my 852 without issue but it is in a 16ft boat. the pump came out of a heavy 24ft that upgraded to the 912, the bigger pump really woke up the boat with the same power in front of it.

"Riverboater" is quite correct that the size and weight of the boat has a big part to play along with power delivery of the engine rather than pure horsepower. So typically anything with forced induction like the LSA / Raptor 575 or big cubic inch engines that have a lot of torque in the lower RPM range are much better on the 912 especially in boats bigger than 20 feet. With the 912 on the same engine, you will push a far bigger load. Having said that the 912 on an LSA or Raptor 575 in a slightly smaller boat is also an awesome combination especially if you like to carry heavy loads.

It's not an exact science so please don't hesitate to chat to your local Scott dealer to get some great advice & guidance.

Curious how the 912 will do on bigger, heavier boats with high horsepower. I have a 25' full hardtop Bloodworth. It weights 6,300 pounds will a full tank. I have a Haxby 572 big block with gobs of torque. I've tweaked the 241 everyway I know how and it still slips. It also is a dog over 4,000 RPM.

Hi, Could you let us know the horsepower and torque please of your engine? If you have a dyno sheet that would be really helpful. Regards

In general terms, we don't see any issues with the 912 being able to handle the boat weight and engine. Look forward to learning a little more about your engine. I have attached our load testing information for the 912 and HJ212 when we had a total boat weight of around 7400lbs. Boat weight ~ 5,970 lbs and load ~ 1,450 lbs giving total weight of ~ 7,400 lbs.

Overall we found that a load of ~2,900 lbs stopped the HJ212 whereas the 912 lifted a load of ~ 3,800 lbs. We didn't test above this load weight.
