Did you do a lot of the work yourself?

OK spill what happened to the other engine brand install, and what brand was it?
The crate had the engine and trans, and new panel and harness. I added the 70 amp alternator and the large panel with all the gauges.
There was about 5K in cost for an expert shipwright and he was worth every penny. I did all the prep work to pull out the old engine and get ready for the new one. I installed a new Racor 500, and also re-formatted a lot of plumbing and wiring in that part of the boat.
There are several blog entries here:
New Location: Racor & Lift Pump - Blogs - EY.o Information Exchange
and also two prior entries.
And more:
New panel cover for engine gauges - Blogs - EY.o Information Exchange

Engine Replacement, Olson 34 - Blogs - EY.o Information Exchange

Anyhow, I wish I was better at this blog stuff!

Note that I had replaced the orig. fuel tank a decade ago, and also all of the hoses. Both shift and throttle had to be adapted to the new engine.
I did all of the work for a new larger OD exhaust system and replaced the transom fitting.

As far as the repowering "road not taken" .... Volvo was out and friends that tried the Vetus have had major problems also.

Thanks for that.

So all in it looks like something between 15 and 20k plus a lot of work plus the fuel tanks from before?

I'll bet the difference in how it feels is substantial. I hear that those engines are really smooth.

The lesson from the Icarus story is not about human failing.
It is a lesson about the limitations of wax as an adhesive.
If you have an engineering problem solve it.

Not quite that much, but I can not value my time too highly, either...
Maybe 17K tops.
The Beta is a lot quieter. While the money is significant, the increased reliability of an all-new drive train is the more important part of this. (Strictly IMHO)

I totally get it. Sounds like the right decision.

Re: Repowering- What to do with Old Engine?

LOL, the yard can have my Vetus! It runs, but it's putting out white smoke. The 3rd cylinder is badly pitted. Having sourced parts for a Vetus (it takes forever to get parts), they can bore it out and put a sleeve in it, or order a new head ($4,500). See what kind of profit they get on a 1991 model.

Re: Repowering- What to do with Old Engine?

White smoke would be steam and suggests a cooling problem. Maybe needs acid run through it's cooling passages for a few hours or the exchanger cleaned, if it has one. New $20 thermostat maybe.

If this did the trick on the smoke and she still runs, I would think a boat buck or more was doable. I suspect it wouldn't be in high demand and the bigger issue is storage (and continued decay) until it sold.

What is your yard telling you will happen to the old motor.

Re: Repowering- What to do with Old Engine?

I changed the thermostat a few years ago, it's fine. Heat exchanger I pulled and cleaned last year. She runs at ~165 degrees F. It's definitely the cylinder head. Spoke with the yard guys. I can take the engine if I'm there with a truck when they pull it. Otherwise it's a core exchange. Taking it home and restoring it is a nice idea, but if the upside is selling a refurbished Vetus, I'll take a hard pass. Unless someone here said to me "Wait! I'll take your Vetus 3.10 20hp diesel engine!"
