As I was navigating CC's new website I noticed they were posting all the engine options for the various models. The standard offerings for the CC28 were Crusader 6.0 375HP gas.....D4 260hp Volvo diesel.....315hp Yanmar diesel.......and D6 310hp Volvo diesel. This got me to thinking with everything going tier-2 and electronic was there a Cummins that would work well.I did some looking and found that the QSD-4.2 liter seemed to be a good fit. I was also curious about conflicting answers I have gotten with regard to the possible fitment of certain combinations of engines, extra fuel and generators. I emailed CC and as most owners will atest they were superior in responding to my questions and did so in a rapid manner. I asked Keith if it was okay if I shared our Q&A with the board and he said that was fine as I let people know these were general answers and that the usual disclaimers were in force ie...specifications subject to change...etc.etc.....he said call him if reguarding any specific situation.
So here it goes.............
My first email to Keith........
I have two questions reguarding the CC28 that I would appreciate your comments on.
#1) I was curious if the Cummins QSD-4.2 was ever considered for powering the CC28.I now this would add require yet another "setup", in adddition to the current four,but it seems to be a good fit to me. From what I can tell it is a little bigger and heavier than than Yanmar but smaller and lighter than the Volvo D6. With the availabilty of Cummins service and offerings in 320 and 350 hp it just seems like an excellent chioce.
#2) I have gotten conflicting answers reguarding the ability to combine the following options; six cylinder diesel engines, extended range diesel fuel tanks and auxiliarry generators. I have heard every answer possible, if you get a six it's no generator and no fuel,six and fuel but no generator, six and generator with no fuel.......etc. etc..... so what combinations are possible. I know there have been some minor changes to the engine bay so if the year of the boat changes the answer I would appreciate knowing that also.
Keith's response to e-mail#1......
>>>"The QSD - 4.2 is not listed on our price sheet, but if someone wanted us to build one we would. We have looked at the measurements and requirements on the engine and they seem to fall in line with what we are currently building."
>>>"As for the engine room layout, you can accommodate both the Volvo D4's and the Yanmar 315's with a generator and extra fuel. The D6 Volvo will accommodate extra fuel, but a generator will be extremely tight and unserviceable. The extra fuel is added by installing two 28 gallon saddle tanks outboard of the engine room where the water and waste tanks are normally located. This is the same configuration as the standard gas boat which brings the total capacity to 256 gallons. The water and waste tanks are then moved to the front of the engine room. We redesigned the water and waste tanks so they would take up less room in the engine room and still have the same capacity. When we redesigned the deck in ' 05 we made the engine room larger by moving the aft bulkhead back. Let me know if there are any more questions."
My second e-mail............
Thank you for your quick responses. I had a couple of followup questions. The best I can tell the Yanmar-315(47.4" LOA) is 9.3 inches shorter than the Volvo D6(56.7"LOA) and 3.8 inches shorter than the Cummins QSD-4.2(51.2" LOA).......Do you think it would be possible to install a generator with the Cummins QSD-4.2 or is the Yanmar so tight to begin with that the loss of 3.8 inches would be too much to make it possible? I know that this is probably a more difficult question than it might appear because sometimes additional factors like the shape of the engine or the placement of other components can be just as important to servicability as general dimensions.
Keith's reply to e-mail#2........
>>>"The Yanmar 315 has approx. 9" between it and the genset at the closest point. The Volvo D6 is approx. 5" longer than the Yanmar with the same gear, but they specify a 7" area forward of the engine for service. This makes the D6 and genset combination too tight for service. From the limited time that I have looked at the 4.2 Cummins dimensions, it appears to be approx. 2" longer than the Yanmar. It seems that the 4.2 Cummins would fit with a genset, however until we looked at it closely, I couldn't say for sure."
>>>"I don't mind if this information is shared on the site, as long as it is understood that there may be factors that could affect the installation of any engine. If a customer was interested enough in the Cummins we would certainly be willing to look into building one, however we have not yet."
The QSD4.2 comes in 270hp, 320hp and 350hp I didn't ask him if they all could be used. I think the combination of service availability, power and economy would make this a killer engine for the CC28.
A couple of other interesting things is to look at the rated fuel capacity in the new specifications and also trolling valves are also available on the CC28 now(according to the 2007 price sheet).
So here it goes.............

is to go with Volvo and Duoprop I/O, so I hopefully will be ordering one soon with that combination.
