Re: Repowering - Newer engine models
There is more to a repower than horsepower. I would pay to talk to some larger marine repower mechanics. While the 4b may be $10K, install and management systems, redoing the fuel system, props, trans adapaters and the like may add more. I think the 4HJ4 is even more money.
Parts for the Cummins may be an issue when compared to the Yanmar or Perkins. Having had several Yanmars, my vote would be for that, assuming it will plug and play.
BEst of luck.
When you only have a few options for horsepower, it's trivial. I know the torque curves are different but gear and prop sizes makes up for that.
There is currently nothing there, no fuel systems, prop(was left on for a decade so it's eaten up beyond repair), the hurth vdrive is shot as well. This isn't my first engine install, I'm not worried about that aspect, I'm asking about the actual engines.
Thanks for the Yanmar vote, but have you used or heard anything about the new 4HJ4?
