There was something about diesel outboards on here a while back, but they were only about 20 or 30hp I think.

I suppose weight is the killer, same reason you don't get many diesel aeroplanes...

slight thread drift here, Will - but: generally outboards are petrol. There are some diesel outboards available but they are hugely expensive, and in the UK very uncommon. Inboards in ribs are usually diesel, and in most (but not all) uk boats in general, but in the US petrol inboards are commonplace on hardboats

You might be surprised. Many jet engines will run on diesel.

Have had 53.2 knots, 62mph - thats with twin 150hp Yamaha HPDI engines - on flat water..

But can reach 50 knots in most water - but not fun when you misjudge a wave


With the twin 115's I had before, I got about 43.1 knots, so about 50mph
