CE emission question

Almost funny .

Gardner engines are so old, I don't think there is any emission specs on them.
The UK factory folded in the 90s.
There is one supporting group still working on them, still in the UK. They may help;

BTW; Beautiful engines. Last forever.

Do you know something we don't, for jumping in such conclusion?
I'm not denying that there are better options than Gardner for repowering a 2021 boat, if you're only aiming at market value maximization.
Then again, there are many if not most boaters out there whose objectives are different.
And anyway, for those whose only aim is economic value, I have a suggestion: forget boats altogether!

The effect any modification or repower has on Market value has to be taken into account in any project. Not doing so would be irresponsible.

when I had to rebuild by DDs, I looked at all scenarios including rebuild the DDs, repower with low HP, similar HP or bigger engines. In the end I went with 435hp Cummins, similar to what hatteras used. It was the option based on my personal usage as well market value should I ever sell.

Maybe the owner is a prepper. One giant EMP and modern diesels might not run. Please wait for me to get my tin foil hat before responding......

On a more serious note, depending on one's use and priorities arguments can be made for a dead simple diesel. If it has fuel and you can get it to turn over it'll run besides being tolerant to damage while still being able to make power.

You have plenty of options for dead simple diesels starting with Cummins factory remans. That s one of the reasons I went with 6CTAs. Simplicity.

Just for the records, it's Gardner that used to build marine diesels - gardeners are the folks who grow plants in gardens.

Anyhow, what you are saying is beyond what Judy disclosed, and is also the reason why I asked if you know something we don't (or I don't, at least).
If the above is correct, I wonder how a new boat could have been registered with a non-emission compliant powerplant in the US to start with, before even considering to bring her to Europe.

Regardless, if she is indeed US flagged, I think the only viable option for cruising legally EU waters is entering under TA (temporary admission) rules, that don't need any emission checks, AFAIK.
The main restriction is an 18 months time limit, but that can be restarted simply by moving the vessel outside EU waters (like to Tunisia, or wherever) and then re-enter. And I think TA is only allowed for non-EU flagged boats owned by non-EU citizens.
No idea if that's compatible with Judy's client needs.

Gardner engines are even too old for apple spailsheik to accept …

Do you mean there's no emission rules all new boats must comply with, in FL?
I'd expect that in Nigeria, if that...

there is a reason why Florida is often called the Free State of Florida. Capped sales tax (max $18k tax regardless of boat value), no emission testing for cars, etc etc etc. And while all Europeans were hiding under their beds in fear of the red flu, it was life as usual here…

Do you mean life as usual aside from fighting the red flu drinking bleach instead of margaritas?
Anyway, if you enjoy FL lifestyle, good for you.
For me, it was the second US State I visited, more than 30 years ago.
Fast forward to present days, having spent quite a bit of time in about two dozens of others (which I have a funny feeling that many FL residents never did), I consider it as one of the most boring and less authentic places in the US.

Yes, I agree 100%. Except for the rural areas it s all
Very fake but at least our freedoms are intact.

Problem over the last 5-10 years is that we ve had a massive influx of people fleeing states that have imposed high taxes and massive regulations on their citizens. These over taxed, over regulated people are moving to Florida, Texas and a few other states. Then we also have had massive illegal immigration in the last 3 1/2 just like Europe has been enduring.
