  • Power for 32

    I'm about ready to pull the trigger on a new 32. Still undecided on power,considering Volvo 435,Cummins 480, or Yanmar 480. Would appreciate any imput re cruise,what rpm's,WOT ,and gal per hr. burn at cruise,as well as any pros or cons.Thanks

    CC32 Numbers

    Billy:

    Call me or email me with your email address and I can shoot you the performance numbers in detail from the PAR tests on the various power packages (Cell 757.286.1582, email [email protected]). These tests have very detailed info on time to plane, efficiency and load data, etc . . . (way too much to post here)

    I have no data on the Yanmar but QSB480 and Volvo D6-435 I have plenty of data. From a performance & efficiency standpoint the QSB480 gets the edge.

    Search under my user name and you will see real world, efficient offshore load data/rpm in recent posts for the 32.

    As always, buy your power based upon access to service. If you are planning to use the boat out of Pirate's Cove/Oregon Inlet/Virginia Beach we handle Cummins and Volvo (in about another month) directly. Not much support, yet, in our market for Yanmar. If the boat is being run out of Hatteras (not our market), I do not know what the service situation is there . . . . Parts cost from cheapest to most expensive: Cummins, Yanmar, Volvo (Yanmar and Volvo a virutal tie).

      Cat's

      Tswann,
      I was just curious if you or any of your customers have ever approached Mac with putting the C7 Cat in the 32?
      Thanks

        C7

        No and have never been asked that (yet). I have not had much experience with the current lineup of Cat Marine offerings. The reputation of the 31xx series of engines and the 34xx series was checkered at best. Cat has a very healthy following in the very large marine engine market (10liters and up) but Cummins really dominates the mid size market and Volvo is making big strides in this segment as well . . . .

        I will however ask if it is possible next time I am at the factory (i.e. is there a space or conifguration issue) . . .

          Specs

          From looking at the specs, the block is 7.2 liters. That is about half way between the size of the 480 cummins and the 540. While I know a 540 (8.1 block) won't fit in a 32, I figured the Cat may be a good engine for the boat. While the C7 is only rated at 460 HP, I would think with extra liter of displacement over the Cummins it would make up for the lack of HP with more torque.

          Just me thinking out loud.

            Personally I would'nt touch a Cat. They still have a lot of proving to do after their last series of engines. I do see your point. It would make a nice fit with more cubes.

            I do believe the QSC's will fit but you wont have a genny or be able to service them very well.

              Cats

              Yeah,
              I had a neighbor that had a 2000 35' with 3126b's at 450 horsepower. Both engines had to be replaced under warranty with approximately 50 hours on them. I figured that with all the new electronic technology, maybe Cat had it together by now...but maybe not.

              Plus maybe the extra weight of the Cat's would mean getting about the same performance as you get with the Cummins.

              I am still a bit concerned with the longevity of the 480 cummins. 480 hp out of a 5.9 block just seems like a set up that will need a rebuild pretty quick. Perhaps, it is just me being unreasonably paranoid.

                One thing about the cummins. All the engines up to the 380 are the same meaning that the lower HP model's are upgradeable to the higher HP versions with maybe a software change. The 425 has a heavier duty lower end and the 480 different again. The 425 is not upgradeable to the 480, at least not cost effectively.

                Maybe Tres can shed some light on the actual difference.

                  what is the difference between the 425 engine and the 480 engine ,same block?,, just different fuel setup? is this what you mean by more expensive to upgrade

                    425 to 480

                    There are a few differences. The turbos are different and the ecm mappings are different. The big difference in the CC install is the gear ratios are different.

                    While the QSBs are probably upgradeable in the gear head 'I can do it because I can do it' sense, in reality it is cost prohibitive. After market prices on ECMs are not cheap, turbos aren't too bad but. . . . Putting a new gear behind the motor is a different $$ story all together.

                      I hear the Cat's C7 have a bigger footprint and are NOISY!
