ahhh yes I remember that one was going in a b28, but any other appear over here? there was a dealer network trying to flog the 300hp hammerhead and this custom 400hp.. did it ever take off? I remember TD mentioning them when we were choosing engine for RedMist, but we went for known package of 315 yanmar/bravo1
in the end the prices were similar, we got a good deal on the yanmar/bravo1x rather than 300 hp marinediesel, think the tuned 400hp was a lot pricier..
so we went for tried and tested with yanmar warranty and service etc
