CD Power Boat - Re-power

[Chris Novack]

I have a 28 fooot CD Open Sport Fisherman with the original Chrysler gas V-8. The compression in some cylinders is less than 100psi. I have been told that it is time to replace or repair. What are the pros/cons of replace/repair? What questions should I be asking? If you have had this done recently what was the total cost. My mechanic is recommending Marine Power fuel injected gas @300HP or a Yanmar turbocharged diesel at a much higher price. I keep the boat on Long Island Sound in New York. Any help and/or suggestions will be appreciated.

My 28 Flybridge was repowered with a Cummins 210 in 1997. I bought it in 1999. It is so good on fuel I can"t believe it. As it was in the boat when I bought it I do not know the price. I am glad it was done. I could not have afforded to do it. A Docter had it before me. The torque makes it very eazy to manuver. Art

I don't suppose you'd consider mounting a mast, boom and a bit of wire?

For what it's worth, our former CD27 had a Yanmar that behaved flawlessly during the 17 years that we owned her.

Good luck,

Chris:

This is just some food for thought.
1. The new gas motor should give you better fuel economy then the old one. Reliability should also increase. The prop may need to be changed (or not). The shaft should be looked at as well. The old one may or may not work. This would depend on the reduction gears and the HP increase.

2. The diesel will cost more. The shaft and prop will have to be changed out as a rule. The reduction gears on the diesel are not always the same as a gas motor due to the torque differance. Reliability will increase with a diesel and the fuel consumption will decrease. Insurance is sometimes less with a diesel as well. The noise may increase and the sound insulation may need upgrading. The exhaust may need to be looked at. I would think that with a Cape Dory, you would come close to getting the differance in cost back when you sell the boat and you would be impressed with the performance.

I hope this helped.

If you are planning to keep the boat for a long time, a diesel is a good investment. The newer diesels have improved horsepower to weight ratio. The fuel is cheaper, and over the long haul that is worth a lot. Diesels are more reliable and will last a lot longer.

And any gasoline boat has the potential of turning into a bomb. Diesel fuel is inherently much safer on a boat.

The only drawback of the twin diesels on my CD 30 powerboat is that they are Volvos. Their pricing for parts is pure extortion.

If it were me, I'd go for the Yanmar.

Chris, are you the Chris Novack I used to work with in Wilmington, NC?

Thanks for all of the input regarding my question on re-powering. Thanks for the recommendation to install a mast, boom etc. The name of my CD 28 power boat is "Clewless". Sorry, I never worked in Maryland.

[Jeff Funston]

If you own a CD you can't be clueless! Oh my mistake thats "Clewless". Good luck on your motor replacement, Keep us all posted.
