Fabio Buzzi started Seatek with few other people and designed the first engine, the design which is still essentially the same as the straight-6 block they use today. But lately, it seems that even Fabio has given up on them and has used more Yanmars, Isotta Fraschinis and CATs. Also, stay away from twin-turbo versions which look tempting and can make 1200+hp. for around 1900lbs. This is a race engine and you all know what that means. |
Re: Diesels
I am still waiting to hear about the MTI that had the D-max in it...Last i saw the boat was rigged but not run.. Wonder if gale banks 750 hp 1000lbs d-max will work..

Re: Diesels
Jeff, a quad installation in a 4300 is going to be very tough. It would have to be straight-6 engine because they are long and narrow. This is why they are such a great idea for performance boats where you usually have plenty of length but little width. A quad Yanmar setup is very complicated to rig in a 49 Hustler and leaves very little room to play with. Access to engines is good because the configuration is what can be described as double stagger but everything needs to be placed to within a fraction of an inch.
Unfortunately, I don't think one would gain anything by going for the 370hp. version. I believe the width is virtually the same, it's the same block. I'm not sure, but you could probably fit three Yanmars in a 4300V. Perhaps the bulkhead would have to be moved forward resulting in a smaller cockpit (and a larger invoice) but you'd probably be able to touch 90, all other things being equal. Which is a big assumption because these boats were initially designed for gas engines and outdrives and were never really intended to carry that much weight in the back. Another thought is Hustler's 444. I hear that the mods have been beneficial and that she runs properly now. I believe the engine compartment is the same as on their 50 meaning that trip Yanmar + ASD8 installation is probably possible. If the 50 with that package runs 85+, then the 444 would probably show some interesting numbers. That is once again assuming that it could run as well as the 50 because this extra length may precisely be what is enabling the 50 to carry all this weight so well. As far as other options are concerned, I know that Buzzi has used Cummins QSM11s on several boats. He used them while they were 635hp. and got some interesting speeds with his RIB 42', I think it was just under 70 mph. Now that they are 715hp, maybe two of those in a 4300V could be an interesting solution. |
Re: Diesels
Jass have you talked to Pat about the 43? It is going to be 9'6" wide from what I hear. You probly have and he laughed at you about the Diesels, I can see it now.

Re: Diesels
Call Ted Mcintyre with MTT. With the size hull your looking to run I would atleast think about turbines.
www.marineturbine.com One turbine would make as much power as 2 diesels at 1/3 of the weight.Just My 2 :D |
