    Hi, new to this site. I have an older Skipjack 25 that I want to repower with a Cummins Diesel. If you know the boat can I get a ball park estimate of that it will cost. I will be needing a new duel prop outdrive as well. Currently its powered by a marine power 5.7 with a volvo 290 out drive

    Thanks
    Tony

    If you have a $70-100K, can find a new Yanmar 4LHA, have a really good shop at your disposal, and put in a year + of free labor, you could do something like this………………. As to a Cummins, no-go for that hull..

    Successful Cummins diesel/outdrive matings are rare, better off using a higher rpm motor like a Yanmar or Volvo.
    Too much torque for the outdrive.

    I am sure just about anything can be done. To me that is a really re invent the wheel type of project. Space being your number one concern. A b series cummins is just to long. If your dead set on a diesel put a d-4 in there. It still is a push to fit with the space you have is a v-8.
