Ecotech

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! Petrol Not Diesel See Mercedes smart 1400cc diesel!

 

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?

 

around 70kg for 75 kw (100hp) Google - Ramphos - (amphibous ultra light aircraft) one of their engine options - aircraft made in Italy & interesting!.

 

Interesting ultralight, but thats is not a marinized engine.

 

http://www.ecotecmarine.com.au/ The Aussies have had it for a few years now. I like the supercharged version, 252 h.p. !

 

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.

For lightweight diesel engines how about looking here?

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

 

(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.
