Yes, and the costs can be breathtaking!

But, they also know what they are doing (except for some in Oceana) and don't waste a great deal of time.

But none of them are much good when you are out at sea and do not have the required equipment.
Even changing a fuel valve (injector) can't achieve much unless you can then retime the system.
At least with a Gardner or similar you can jack up one, two or more fuel pumps and run on the remaining cylinders.

Cheers
Benn

Can Watson do a new build, and the client take the risk, without adhering to Tier III/IV requirements. Nordhavn cannot.

Reading their web site they still offer Gardner rebuilds as an engine choice.
Cheers

I can't speak to the issue of Australian emissions regulations but the Tier 3 and 4 that Americans spend so much time talking about needs a little clarification.


Rather than directly quote or attempt to paraphrase the legalese, just read the EPA link.

The EU has its own Tier system that is very similar to the US EPA, and the IMO has its version as well. They are fairly closely harmonized but unless you read and understand the regs you may easily be lead astray by internet gurus.

Before I bought an engine, or did not buy an engine, I would find out exactly what applies rather than take guidance from some of the posts in this forum.

Rick,
here in Australia unless the vessel is going into commercial survey there is not a lot of checking on compliance especially in the rebuild, one off build home build situation.
Compliance checks are only carried out by flag state, Individual state surveyors etc.
All commercial builds must comply with our EPA regs.
Cheers
Benn

Thanks Benn.

The link I forgot to paste last night for American readers is:

Caterpillar has recently reintroduced the 3406C mechanical injection engine. Not available in the US of course, but this is the forerunner of the C15 and 3406E. The 3406C is 14.6L and available in various ratings up to 535hp and 2000NM.
It is still in commercial use world-wide in ferries, fishing boats, patrol boats as well as many recreational vessels , including mine, and, with a 3:1 transmission it would probably suit the Watson 72.

Look into that cat 3406c. All mechanical like a Gardner. Excellent engine with a huge installed population. Only issue is your local emissions issues.

I actually want to buy this engine myself but haven't got the hull to fit it into yet.

Apparently the last brand new Gardner left and with a very reputable South Pacific company.
Any boatbuilder that doesn't want to fit this beauty needs serious counselling.
