So let's compare it to another inline 6, 4 stroke engine in the market in that same hp range. The Caterpillar C-12E engine has a listed size of: 62" Long x 39.5" tall x 38.1" wide and has a listed weight of 2588 lbs and an output of about 600 hp. (this is taken off of http://marine.cat.com/cda/layout?f=200499&m=214842&x=7 if you want to look it up yourself)
Our engine measures 60" long x 29.7" tall x 28.9" wide, weighs in at 1500 lbs, and has an estimated 650 hp. (The dimensions of our engine are shown here: http://buckdiesel.com/index.php?Section=Specs)
This is purely a dimensional comparison. This does not take into account the fact that our engine is MUCH easier to work on, should be more fuel efficient, and will be available at a competitive price. Overall, we have a list of about 55 improvements that our engine has over a conventional diesel engine.
If you would like to hear more, let me know.

My opinions on the Buck engine are on the website here somewhere? In a nut shell not you or Buck itself but other people were pushing these engines as an alternative to regular diesels and these could be the performance answer.
I thought on the website before there was mention of Hp ratings and rpm's???? When I looked there today I don't see them and I thought the engine was being presented as a slower turning engine much slower than your talking about here?
I think I quoted what was on your site and commented - "it won't work for these applications"
When I go to website today it seems a little more tangiable that's good to see and I wish you luck.
If it truley weighs 1,350 lbs dressed minus trans, turns 3,500 rpm's and makes 800 continuious Hp you probably have something there.
I'm guessing with that engine your whole marketing strategy has changed then and you're going after "performance" boats?
With that said what kind of turbo(s) are you running (fixed, VG's, seq, bi, etc)?
How are you going to generate lower RPM boost than a Yanmar, Cat or Cummins?
What will make your engine accelerate better than say a Cummins when that big cleaver is fully submerged under water (don't tell me vent tubes or multispeed trans because then your no better than anyone else!)?
How did you loose 150 lbs on the performance version?
Are you still using the SAE #2 bell housing?
Checked out the web site. I see a lot of high quality machined parts. What i don't see is how all that quality is gonna translate into a less expensive end product.
As far as I know, the engines have always been touted as having a max of 3500 rpm...
We are using a lighter rotating assembly which will improve throttle response and therefore reach maximum rpm faster and maximum boost sooner.
Keep us informed it should be exciting, sounds like your still far from running test iron in boats let alone production. Hopefully the economy won't take it's toll on your project.
We are working on raising the capital to take things into full-scale production. We believe once we have the capital, we will have the first engines available in about a year and a half to two years.
Yes, the economy is a big worry, but we feel we are getting into things at about the right time. The economy has to rebound sometime. Hopefully things will be picking back up in those 2 years it will take us to get production set up
The modular cylinder kinda reminds me of a Deutz. Doug
