research Cummins 6b's

Well, If you want to get to around 34-37 MPH, considerably more than 10, I have a pair of Medusa 400s that I just installed in a Hatteras but after getting a taste of increased speed, the owner wants to move up to Medusa 500s, so I have this pair of Medusa 400s, (430 HP/470 lbs.ft.) that have 18 hours on them and less than a month installed, that I'm willing to let go for $19K instead of the $24.5K they go for. 5 year warranty. Oh, and 650 lbs per unit as opposed to 1800 lbs.

Just another option.

Hi Byron. 

A pair of Cummins sounds like a fine idea. John Deere's look pretty interesting too. At this point it's going to be a stretch to just get an old pair of two-strokes that'll get the job done.

I'm weighing a repower against parting company with Chowderhead and moving on to something with more range and capability. She's a great old girl and she can slay sea monsters with the right powerplants. I love her dearly but repowering is a one-way investment.

Hi Rudi.

Thanks for your note.  Switching over to gasoline is tempting but I don't have that much by way of budget and diesel has won me over.

She is #20 of 70 and if you really like her, 30 makes her yours :)

Do you have any online videos of the sea trials?

A question ?

Would 871s be a good fit?

Would 692s be a good fit?

What would the be best diesel conversion for the 38' Commander.

Assuming 18 knots

Thanks,

Pat  

Pat,

8V71s, low profile version are 5.5 in. wider than the 8V53. This will end up giving you around 12-15in. clearance between the outside hull and the engine and maybe 24-28in. between the engines. These are best case clearances and likely would be tighter then this.

Th real killer is that the 8V71 which uses the Allison transmission has the transmission output 8.5in. below the crankshaft C.L. making the installed engine around 12in. taller over the 8V53. To make this height even worse is the issue that the 8V53 is rather wedge shaped in the front allowing an 8V53 to be installed at the propshaft angle without increasing the overall height. The 8V71 is rather boxy and if it is installed at an angle will increase the height even more. If you use a different trans mission, then you might improve the height problem slightly.

The 6V92T and especially the 6V92TA is a definite not going to fit.

Cat 3208TAs , Cummins inline 6BTA, John Deere 6090 series, Yanamar, would all be better choices.

There is also the Sweden Marine VGT series which is a marinized GM DMax which currently is not real popular yet but appears to offer a lot of potential. Rated upto 450hp with a 3000hr mtbo.

For a 38 hull, I think that you would be happiest with an inline 6 engine. More room on both sides of the engines.

I was thinking there were some 300 hp 4-71 TI's made - Johnson and Towers built ?
