Long stroke heavy piston the harmonics will just tear a V-8 apart. That is why you can go down to your local Cummins dealer and buy a 480hp 5.9L marine engine. Or your Local Yanmar dealer and do the same thing. Every so often someone puts some hell a built up D-Max on display at a boat show and says they gonna start production and then disappears. What happens is they get to the point of doing destructive dyno testing and they realize the engine won't hold together at a marketable horsepower level. At that point they fade into the darkness never to be heard again. If the Duramax was really doable it would be on the market already.:drink:
Your knowledge of V8 diesels is laughable, so please if all you can do is call me gay:drink: go crawl back under your rock. I dont bust on you for whatever you want to do, so just keep that in mind.:eek: |

Yes but it's still only about 500hp right?
When I get some time, I am going to try it. Need to find me a project boat though....and I will need some help selecting drives and props...ya know the "boat" parts. Thanks for writing civilised post. Waid |

It's not like it's not been done before, it has - I have done it so you got me on a roll now! 7X champ is on here, he's seen our fast diesel boats, Craig Barrie and Bud have been on them almost 20 years ago (1990) and into the 80's mph was not an issue. Just go to Italy and you'll see plenty of fast diesel boats. R&D, it's been done, all the people you've dealt with have been to blind to see what is in front of them everyday and how things work. I'll be really bold here and say just because you can build a fancy boat that sells really well doesn't mean you know how to engineer propulsions systems. Most Boat builders I've met over the years know little about engines, they call merc or whoever and say give me 2 600 hp engines and slap black drives behind them with 1:50 ratios and start playing the prop game. That doesn't work with diesels, that simple. What scares most people is doing something they have never done so they just go with what they know and not what they are unfamilar with. Like catmando said Weisman has gear boxes, ZF has gear boxes and you can use a Lenco if you wanted to R&D something. |
Wolford - when you make statements like this:
"The drag racing boys are running them a 1200hp and they arent having problems with the motor" Any crediablity you gain you loose 5 fold. It goes back to how many Hp get you get from 500cui gas engine - way over 2,000, not hard and people do it all the time. What is no trouble to John Force with his nitro engines is unacceptable for a pro-stock racer - so everything is relative. You can't run a pro stcok engine in a NASCAR - right? Do you understand when you make those statements everybody just thinks your talking with no degree of experience at all. I'm sorry, |

I'm done with this thread. Bash away.

You haven't given one tangiable shred of proof you even have a boat, let alone a diesel (unless I missed it).
Pride, in what the fact that everone here basically says they want to go faster with a diesel but don't know how, that they are a litttle reluctant to use their own money for R&D? They're a lot smarter than me, with alot less pride - I allowed my pride to get the best of me, over developing stupid diesel engines so much so I lost track of our business and well that didn't turn out so good! I never got back to what we were - I'm a smuck! If your so damm smart and so successful with your contracting and your boat is so damm fast so some pics, share a little - do I put my pics out here, my name, face, everything - yes. Call me stupid, call me a looser, call me an azzhole but, never a poser! |
maybe your right end this thread it's too old already!

a single speed tranny like I had in my 15k boat with the 480 Yanmars and ASD-8's went 74.6 How do I get this boat to around upper 80's. Tyson can make me a 3 speed tranny or Weisman and ZF I believe are 2 speeds. By clicking in to the next gear.. what is required. any videos of what you are talking about.. or give me some boat that I can do some research on. Thanks Jeff
www.weismann.net [In 1996, Zero Defect was rigged with Weismann 3 speed transmissions and dry sump Six drives(Mercury didn't have dry sump drives in those days). The boat could downshift coming into a corner which gave it tremendous acceleration out of the corner, which the other boats could not do. As a result, ZD won every race it entered. Nobody else had a chance unless ZD broke, and they never did. After the season, the drivers called a meeting and banned dry sump drives and multispeed transmissions.] |
