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.
