any speed #s

Mike,

The 39 Diesel Rockit has not run yet as they are Prototype 6.7 Liter Cummins-Mercruiser Diesel motors. We are doing all the testing for Cummins-Mercruiser on these motors and hoping to run the boat within the next few months. Hustler and CMD estimate the speed between 90 to 100mph. Stay tuned for data of the boat running as it will be posted online as soon as we test the boat.

i think those 6.7 l motor's are the same as the FPT 560 hp motor's , if so they should run good :)

mike

That would be a great speed for diesels !
Do you use multi speed transmissions or regular?

I own A 32 LE which I convert to diesel whit 2 CMD QSD 320hp on xr drives ,love the diesels !

Keep us posted !

bor

not exactly the same ,bore x stroke on the cummins is : 107 mm x 124 mm
on the FPT bore x stroke : 104 mm x 132 mm ,blocks look identical ,makes you think FPT only buys a bare block&head,but it could be they ordered this at Cummins ..who,knows ?

Actually I think it´s the other way. FPT makes the engines for Cummins.

Why makes you think this ? the Cummins 5,9L is a dinosaur engine produced by Cummins for a more than 25 years and known as the B series just like the 6,7 L ( B6,7 )

I'm interested in seeing some real data on speed and acceleration along with mpg

Any new news on the diesel Rockit? Has it been run yet? I think its a great project.

Bondo,

We have not tested the boat yet, but it will be completed in the next 2 to 3 weeks. We will be announcing the results on Facebook and Twitter so stay tuned for that!

Did the Rockit get tested yet?

Talked with them this morning. sounds like they are going to get out today.Will post if I hear anything.

any new's on the test run

thank's
mike

Yes Mike,

We just completed our first phase of testing the 39 Diesel Rockit as we hit 84 mph with motors that are rated between 460 to 480 HP. These motors will be replaced with motors that are rated between 500 to 550 HP. You can read a bit more about it in our press release as we also have a picture of the boat running here:

Paul,
congrats to the whole crew at Hustler, can't wait to see the #'s with the 500-550 engines. Sweet looking boat also.
Dean

Great numbers!

Excellent and congrats! What a great setup...

nice work

that's a BAD AZZ setup!
what are fuel numbers? any data on that yet?

Joe and Paul.. first off..georgeous boat..best looking and running 39 out there. The 550hp diesels..is it the same block slightly turned up..or is it an entirely different motor. Secondly, have you thought about some Yanmars and Asd-8's..or even the light weight diesel that OL did..I just cant remember the name of that diesel.. Thanks Jeff.

Jeff,
I think this was a partnership between Hustler and Merc, hence the choice of engines and drives. I have to agree though, Yanmars and Asd-8's would make for another nice combination!

Great looking boat though....

Jeff,

To answer your question, they are the same block, just slightly tuned up. The Yanmar/ASD package is durable, would consider doing it if we had a customer interested in building one.

Paul

Mwdill,

We do not have any fuel numbers yet as we are focusing on the performance of the boat right now. The next time we take the boat out, we will get some MPG numbers at each RPM level to give us a general idea of what we are burning.

Paul

Im anxious to hear what the 500-550 hp version will do. 84mph is strong..but +90 is awesome.

Wrong. Cummins builds all its motors in house.

Ok. Belive you. The Italians told me that they made the 6,7 baseengine for Cummins...

Seems like there's a lot of misinformation about these engines.

Perhaps Cummins could jump in and give some information?

We are currently working with the Cummins people right now to get the correct answer for all this information. In the meantime, the 39 Diesel Rockit Video is up on YouTube. Here is the link: http://www.youtube.com/user/HustlerP...s?feature=mhee

More detailed data is coming soon.

Diesel Rockit Update
 

Hello All,

We put new props onto the Diesel Rockit, and the boat picked up 2 mph. With a top speed of 85 mph, we are very sure with the addition of 140 hp (70 hp per motor) that the boat will see the low 90's with the new 6.7 liter, 550 hp Cummins-Mercruiser motors will make the boat a low 90 mph boat. We will be posting up the fuel burn numbers at differen RPM levels within the next week. If you have any questions, please let me know. Thanks!

Paul

Paul..awesome numbers, extremely effecient hull...dont forget the video..best looking 39 out there. Thanks Jeff

Thanks Jeff,

I'll get video up as well, If I don't get it up next week, I will at least get it up when we put the new motors into the boat in August.

All the best!
Paul

Thanks Paul, looking forward to it.. is it possible to start video as to when the boat planes up vs it running almost on plane...Im curious to see if it takes just a little longer vs a gas or is it about the same..Thanks Jeff

also, how are the acceleration numbers? or are you just taking it easy right now?

thanks, Will

hi guys, i've not posted in a blog room for probably 5 years...thanks for letting me post in your blog..

i'm a sunny owner looking to move to the 36 to 39 range now..

i have to say..this is so exciting..as a turbo diesel lover in trucks... i cant wait to see how this all pans out. does hustler do any mid cabin open bow boats? i've never considered hustler..in the past..as i love the mcob layout in the 32 sunsation..i'm looking to move up and was thinking of the 36 mcob sunsation..now i want this dam twin TD hustler ...

my guess is that the fuel economy is gonna be much, much, much better than twin supercharged bb gassers.

be well, keith

Interesting thread.
I'd sure like more info on these higher HP merc diesels for a single engine project in the future.
I've read up on Seatech's but Merc dealer support would be very nice to rely on.

No, unfortunately they don't.
