Any comments, or information when and where it will be available? There is quite a buzz in the river jet community.

Be awesome in some of the older designs
I am anxiously awaiting word too. It would be an awesome powerplant in some of the older 1930 gentleman runabout designs!

Bah!
Bah! How can you put an engine in a planing powerboat and still have the word "eco" in its name.

Well I have never seen a Mercedes Marine engine in the USA. How much does it weigh?

There is a pre-production engine at Marine Power in Lewiston Idaho. It will be debuted at the Portland boat show. May be available by summer.

Awesome
This will be a boon for some of the older designs from the 30s and 40s. I figure with a zf tranny it should be about 400lbs total. The Austrailian web site state the marinized engine alone was 313lbs (conversion from kg). I have been looking at several of the older designs to build.

Masalai,
Please stay on topic. Once again that is an aircraft engine. Lightweight, sure; but why would I spend, per the website $28,000 USD on something I would have to fabricate marinization parts for?

In the vein hope someone would counter with "this is better". I am still up against a brick wall for a fuel efficient (6litres/hour) 100hp diesel which is NOT heavy and will fit within a 600 mm width. Initially I thought ecotech was diesel ergo dummy spit. Cheers

Location: Conn in summers , Ortona FL in winter , with big dock & room for O'nite stop .
(6litres/hour) 100hp diesel

It will be a very long wait as you are looking for efficiency that does not yet exist , even in the most efficient HUGE SHIPS diesel are just over 55%.

A crappy 1930's diesel (DD 6-71) will give 16hp per gallon (US) if fuel on about 2800 lbs installed weight.

The newest most modern electronic injection turboed & intercooled diesels will give almost 25hp per gallon , but you risk dead in the water at all times.And immense complexity and maint issues.

100hp will cost 4 gph IN OPERATING COSTS in 2007,, with very good engineering.
