I use a Yam 200hpdi on a fairly regular basis for both slow speed and high speed work. Its fitted onto a 7.2m MCA Coded rib with 55 gal fuel. Excellent reponse when needed in rough weather. Good overall fuel economy. I have a fuel comp fitted and @ 25 knots it reads 6 gph.
No smoke or coughing at all even after 6 hours of nothing above 6 knots.
Servicing has also surprised me how reasonable the price was and my local Yam agent.

Is your local agent Chris Hoyle at Kingswear by any chance, or is ther one closer to you in Brixham?

Also is there a minimum size of Rib to install a diesel in?

Humber had the 5.5 extreme with this fitted Mercrusier 1.7L DTI is is a 90 desiel. They were quoting good figures for it. Cant remember what show it was at, but looked promising.

They big thing of how compact the 1.7 desiel is hence why they could fit it in such a small boat, even smaller i guess

Just out of interest, was the Wankel engine ever developed into a marine engine? I'd have thought that it's light weight, simplicity and ability to run whilst upside down (well it doesn't really have an upside down) would have made it an ideal candidate.

Keith (genuine question) Hart

that a very good point, but then again there more thirsty than 2 strokes due to there high 'hp' to 'cc' ratio.

i used to pit crew for a rally car that had a 1.1 wankel in it, but it was classified as a 1.7 because then small unit was so powerful!

will have to look into that seeing as they have stucks rockets into boats but not a wankel
