Bertram 43' Sportfish Repower

Hey all,
This is my first post!
Need help with info on repower of a 1989 43' Bertram Sportfish, power on board is (2) 6-92TA Detroit Diesels, 550HP when new. What are the problems associated with this type of project? What engines do you recommend? Any help is appreciated.

Thanks

Are the existing engines not worth rebuilding ?

COST! while older Bertrams or Hatteras are probalby the most worth of a repower, the costs are very high. If you intend on keeping the boat for a long time it will be worth it but otherwise you'll never recover the cost when it comes time to sell.

I don't know at this point. We were considering fuel efficency and cruise speed as one reason to repower.

That is one of our main considerations, don't know how long we will keep the boat. The hull and the rest of the boat are in very good shape though. Thanks guys

I also have a Bertram 43 with DD 6v92's and have been considering repower. As pointed out earlier, cost benefit analysis is big question. Looks like the Cummins QSC at 600hp is the best alternative. There is a 43 in Puerto Rica currently being repowered with Cat C15. Check out boatdiesel.com for information and pictures on the 43 in Puerto Rica. Dont know how to resize pictures for posting, but I have pictures of Cummins QSM repower of 43 by Unlimited yacht Services in Florida... if you are interested send me a private message.

reopower 43

I have seen 43 get 8 cylinder mans. The neg on the mans is they are expensive to maintain, tend to smoke at idle. I think the best choice would be the 8.3 liter c series cummins at 540 or 600 hp. The new common rail mans make more hp. but are expensive.
