Cummins Qsd4.2 320 Hp Vs Volvo D4 300 Hp
 

I am repowering a seacraft 25 Seafari. I was wondering if anyone had a recommendation between these two engines. We would be going with a volvo duoprop sterndrive for the D4 and a Bravo 3 for the Cummins.

Thanks, Gary

All I know is the duoprops do get good fuel milege and are pretty bullit proof, But the Merc's have relly good paint.

Hey bayouboy,

Haven't had any experience with Cummins yet. The new boat will be a Cummins and is still being built. The old one in the Hawaiian Seacraft thread had a Volvo 200 diesel in it. Volvo service wasn't a problem for us as we could do most of the work ourselves. If we couldn't my brother had a friend who is a Volvo Penta mechanic :D I have heard many good things from friends about Cummins diesels. Aloha, Greg

BTW how's you hand?

YF...Hand is on the mend...thanks. I've started back to working on the Tsunami.... :cool:

I have some buddies that work at Cummins Mercruiser Diesel....while I'm no expert I do see their engines quite a bit. One has a 20' Bertram Moppie he put a 200HP w/ Bravo I in....another is redoing a 28 Donzi with twin 360HP. I've even got to see the new Zeus drives in action. They're good rep is well deserved.

Yeah, I am from Hawaii, I grew up in Kailua, Oahu but I live in town now. I still fish the windward side for the most part, but I ended up in Waianae a lot this year. On another subject, do you know the history behind the yellowfin hull. I have heard that it is a modified seacraft 23. They definately flattened the deadrise in the aft section of the hull, and I have also heard that they widened it a bit. If you have any other info I would be interested to know. P.S. The Ahis are still here, my friend got 3 last weekend.

bayouboy,

Do you have a friend at CMD who is a mechanic? I would like to get true information re: the weak points or trouble areas of some of their products. Glad your hand is doing well. What's YF? GOD Bless and take it easy, Greg

Gary,

PM me with your email addy and we can correspond that way. I went to school with the son of the originator of the SaltWater/Yellowfin hull. Aloha, Greg
