Scott 912 readied for the GM 6.2 DI & Raptor 440/460's

Postby Scottwaterjet » Wed Dec 12, 2018 10:17 pm

Customer demand has accelerated our efforts to have the 912 available to match up with the GM 6.2DI and Raptor 440/460’s.

We have been very busy supplying the 912 for river boats with GM LSA’s, Raptor 575’s, and custom engine builds. The results have been fantastic for both retrofit and new build customers.

Both the GM 6.2 DI and Indmar Raptor 440/460's engines have been on our radar for some time as they have an aggressive torque curve that is ideally matched to our 912 pump. The 912 is able to maximise the engines power delivery without the compromise of slip/cavitation whilst offering exceptional drivability providing great engine/jet combinations for jet boaters.

We are pleased to announce that the order for our first install of a 912 utilising a 6.2DI engine was placed in the last few days. This installation is for a retrofit so we are hopeful that we will be able to gather some before and after data to share with you all.

It’s fair to say that we are very excited by this next phase of 912 development. We look forward to making the benefits of the 912 Two-stage with Trim available to a wider number of jet boaters: more grip, more push, more lifting power, better load carrying, better-cruising speed, and ability to utilise the available capabilities of your engine.

What pump and motor combo is getting replaced? Or is the retrofit just replacing the pump?

Just the pump is being replaced. The 912 is replacing an HJ213.

A quick update
Some testing of a 6.2DI and HJ213 combination was completed today. The HJ213 will now be retrofitted with the 912.
When we have some test results of the 6.2DI \ 912 combination we will let you know. We are looking forward to the relative test results.

Since the 213 can handle the 6.2di just fine is it safe to say we will not see the benefit as much as with the lsa? Maybe the only real difference will be the trim and adjustable nozzle?

Hi Benny,
We are expecting more. We are expecting: Better grip, white-water performance, push, load lifting, load carrying, and cruising speed.
.
How: Two-stage pump (greater blade area, two-stage white water performance), trim (effectively able to actively adjust your boat trim for best holeshot, cruise etc) and designed to better utilise the high torque modern V8 engines.

Please expand on the term "high torque" and its role in jet boat operation. As a discussion aid, please consider comparison with a less modern engine such as the 8.1 HO.

Hi Viking, Would you have a torque curve for the 8.1 HO?

My browser chops off the bottom of this figure unless I click on it. I tried replacing it with a jpeg, but to no avail.

Not much of a curve! That graph is saying an 8.1 ho makes over 800 ft lbs of torque! Am I reading that rt?

if a 8.1 made 800 # tq it would still reign supreme.

Torque is the flatter line referenced to the axis on the right.
