Default Re-Power - 32 Blackfin Combi

I have been trying to sell my Blackfin for a while and keep dropping the price but with the boat market where it is she has still not sold. I have the price down to $47,500 which I think is pretty darn low for that boat.

I am now thinking if she doesn't sell, maybe it's time for a re-power instead. The ride of the boat is that good that I think it just might be worth it. I have been told most people to go the 370 Cummins which I think should give a 26 knot cruise in real word conditions. Does anyone have any experience with re-powering a 32 combi and what power did you choose, fuel burn, cruise etc...?

Default the cummins repowers are great.

that blackfin is built strong.. weight to hp to fuel burn is a plus..
getting stuff out.. changing wires, hoses exhaust if needed, is a plus.. keep it simple and check your tank most blackfins were plumbed with fuel return lines also.. mounting it in place and making it look and perform right is the trick .. most engine co. like to mount and start their product though.. having everything right is what makes the job easy and cost efficient either way.

QSB425. You will never regret the decision.

I bet the right props will get you a 30 knot cruise and no smoke.

Most of the repowers I have seen done on 32 Combi's are with Cummins B370 remans, for one real good reason - on a cost basis they are by far the best value. You can buy a new pair B370 recons from Cummins with a full warranty and new ZF-220A gears for $45k. If you are willing to go with 1.53:1 or 1.235:1 ratio's you can reuse all of your running gear, and the cost of the repower will be about $55-60k, depending upon what else needs to be done.
B370 (actually 355 hp @ 3,000 rpm) will give an honest 25/26 kts cruise and 30 kts on top with just about 1.0 nmpg fuel efficiency.

The QSB 425's would be really nice, and fit with no issues. They will get you a 28/29 kts cruise 33 top end at about the same economy. The issue with the 425's is purely cost. QSB 425's with ZF-280A will set you back $80k; then all new running gear will be another $10k, and lots more labor on other parts, so you are looking at somewhere around $105-110k for that type of repower.

As an aside, your asking price is just about spot on (assuming it is a diesel boat with 8.2's) - selling wil be a little less, but finding a buyer for an 8.2 repower project, which is what you have is tough in this market.

I think you can also still get 370B factory remans for about 16.5k ea with a two year or 2000 hr warranty?

If you repower you will end up with a very nice boat. But the reality of today's market is that you can buy something like what you would end up with for a lot less money. If you repower the boat, do it with the intention of keeping it for a long time, don't do it with the idea that you'll now have a $100,000 boat that will be easier to sell, because it won't be. You may end up with a boat worth $70,000 that your into for $30,000, or more, than it's worth. If that's a gas powered boat, and you can't seem to get any takers, it's probably because it's overpriced. We all like to think our boats worth a lot, because to us, it is. But everything from houses to cars to boats, their only worth what someone else is willing to pay for it. You might be better off in the long run if you lower your price enough to sell the boat. Don't feel so bad, when your a buyer, your going to be paying out less as well, so it's probably a wash at that point.

Good luck

John

I dont know the year of the boat but this is how I look at it,Figure that boat will sell for 42.A repower is 55 to 60,So your in for around 100k.
Can you get something better that you would want in that price range.If not repower it.

It has the 8.2 Detroits and we have had it for 15 years and no major engine issues beyond the normal maintenance etc...The engines are still strong, but I know the internet market for these engines. If I do a re-power I am going to keep it for a long time. If I could get something in the mid high 40's I would let it go, but I'm not going to take $30K for a great boat.

if the engines have no major issues beyond normal maintenance and are still strong then why in the world would you repower? you are right that the 8.2's have a poor 'internet market' but that is a terrible reason to repower if you are going to keep it. repowering engines with no issues doesn't make sense.

every potential buyer is doing the same +/- calculations you are...it's a great hull but the next buyer is contemplating the ~$60k bill that's on the way.

if you still enjoy the boat and the engines are trouble free and strong then i think the best course of action is to use it as is.

That is right for the engines alone, but he also needs the gears (which are $3,000 ea), mounts, wiring harness, exhaust elbows and risers ($2,500 ea engine).

If he logged into our forum www.blackfinforums.com, he would learn how to do that stainless exhaust for a whole lot less

Just to let you know Riprunner, the cummins 370 hp has the exact same foot print as the 8.2's, except they have to be mounted 1" more forward then the 8.2's. I already a while ago sold my 8.2's, the guy who found the new owner, has been with Atlantic Detroit Diesel for 25 years and loves them. I do know another person that might be interested, but I wasn't asking for much, I let them go for 5k for both and gears, The way I saw it, my money was already spent so I wanted to help someone do a reasonable priced diesel conversion

Mike - you could pull out your new half installed B370's and sell them to the OP for what you paid, which would allow him to do a cheap repower and put in some QSB's. In your case though, those QSB's need to be 480's.

What is the reality of me being able to keep the same shafts with the 370B's?

I would love to talk to someone who has done this re-power.

Thanks guys.

On the Blackfin forum, contact Skipster, he has a 1990 Combi that he did a B370 repower he did 4-5 years ago.

So, the re-power is done and based on things that needed be done and other stuff it was way...way...more $ than I thought.

With that said, this boat now rocks. Honest 25-26 knot cruise and just over 30 on top and rides much flatter/bow down. I went with 5 foot long Sound Down Mufflers and she's relatively quite too.

The only issue in the whole build is with ZF. Both trasmissions leaked heavily on the sea-trial. One was a simle fix and the other was a bad trolling valve. ZF eventually got down there and put in a used valve to get me running. (used valve on a brand new repower...great!). Well it never worked, not once and it's now a month later and my new trolling valve is still in Italy where the trolling valves are made. Total BS on ZF's part. I hear that lots of trolling valves are back ordered on many models, my guess is they get the parts from Japan.

Anyway, the 32 Blackfin combi with 370B's is a great choice if you are going to through in new iron. My perfectly good 8.2's and twin disc transmissions with working trolling valves are still for sale. $4K....best offer...I would like to get rid of these now so no reasonable offer would be refused.
