Price of new Diesels

[osprey47]

I am running through the numbers on a build from scratch vs used 35' to 37', purely for cruising so looking to keep fuel consumption down. Tough finding pricing for new complete diesels in the 220 to 370hp range. Any assist on 'ballparking' cost of engine NOT including install would be appreciated.

I got a 260 Cummins to go into an older hull, no TIER regs, at $21000 with a trolling gear, basic panel. This engine is one of those factory rebuild's, zero hour. Its funny because I've seen lower prices but when you put it together this is what I got. I was also looking at putting in a D4-260ish Volvo, brand new, that was something like $28,000 or $30,000.

I never went through with any of these, sold the boat beforehand...

Since this is a new build you are going to have to install a Tier compliant engine, unless you want to fake it. A Cummins QSB 380 or the Volvo mentioned above are going to cost in the $30K range.

To me, it was worth to buy an old hull, where the engine is mechanical because I know I will always be able to work on it... I do not know how the years worked out...

I look at these prices and have a hard time trying to figure it out anymore... Just the price it adds to new boats...

Even more discouraging about the new engines is the money it adds to repowering older boats that don't hold so much value these days. Makes it really hard to justify the expense if you contemplate what you could get for a boat if you have to sell her or if you find a great deal on a bigger boat and want to upgrade at some point. Even the factory rebuilt Cummins engines have skyrocketed in price since their introduction a few years ago. It's a depressing prospect when you have a Detroit or a Mack or something that's long been out of production and you don't want to put new kits in again. Of course there would be a lot less boat owners if we had to justify the expenses that come w/ boat ownership. Break Out Another Thousand has become Break Out Additional ThousandS.

So, I am fast concluding that buying used is the path; maybe find a pre common rail, ECU diesel that can be worked on, and any boat I do look at will include a thorough going over by a well regarded diesel mechanic/surveyor .. finding one is always a challenge.

I bought a dealer rebuilt 3208 435hp CAt with twin disc 507 for 23K. They quoted 18K for the 375hp version.

 

[petrel]

Wow. It seems like top dollar for one of those old Cats, but I got a quote on a bobtail rebuilt 3208 which was 320hp and that was $13,500 before gauges and a wet elbow. Ended up w/ a 315hp B series ReCon and that was $18,500 w/o the core charge b/c I had one. Seems like a lot for such a little engine, but thank God I don't need another couple hundred horsepower. At least it's got two years of warranty included and the boat is set up for it.

I had committed to one of the Cummins also but the shop doing the R&R said they only had time to do a Cat for Cat swap and not a Cat for Cummins. Anyway, 4 months after the deadline they gave me, they had the engine installed and I missed the Cook Inlet fishing season!

 

[petrel]

Four months would seem like an eternity. I get antsy when things are running a week or two behind, which of course they are, but I did get an engine really quick. Then it took another week to get the gear looked at. Anyhow, my instincts were right. Inside looked as bad as the outside.

Way it's going, I might miss some of the King Mack season here, but if it's like the last three years, I will not have missed many days of fishing.

 

[5akman]

Commercial fishing for me is a hobby that occasionally pays for itself (according to my wife) but not this year! I hate it when she's right....

That is a really great price. My only reservation would be the manifold failure statement. That always means that salt water went into the engine which is why the manifold just wasn't replaced in the boat under warranty. Question is who is rolling the dice, the buyer or Cummins...their warranty is pretty darn good. http://www.cmdmarine.com/documents/4081872_0708.pdf

have never heard sea water get into a motor from the manifold..maybe coolant going into exhaust. Most water cooled manifolds are cooled by engine coolant not sea water

Call Tom Directly. He is a straight shooter & will tell you exactly what he repaired and why it failed. Good , Bad, Or indifferent, He tells it the way it is.
It was probably an exhaust manifold failure. I've always found him to be an honorable guy.
FWIW,
