You really are gullible aren't you William??? these people are sellers!!!

"32’ Hatteras Express, Gas to Diesel Conversion"

"1983 Hatteras 32 Sportfish had her old Mercruiser 454's removed and Grover's
Team installed new Yanmar 315's. The Merc's produced an 18 knots cruise burning
40gal/hr. She now cruises 25-26 knots burning just 18 gal/hr, top @ 31 kt"

Gee a testimonial that's really reliable probably in the same class as
the other magazine something to sell rubbish. For any fuel consumption
figures to be valid they need to tell exactly how the fuel usage was
measured, needless to say the spruikers don't & never do.



"34’ Atlantic, Gas to Diesel Conversion"

"1992 Atlantic 34, SHANGRI-LA, had the old Crusader 454's removed and Grover's
Team installed 2003 Yanmar 315's to achieve cruise speed of 26.5 kt @ 3400 rpm,
top speed 32kt. Cruise consumption is 18 gal/hr."

This is slightly more realistic but again why quote marketing spruik to
me, all you need do is find just one "Yanmar" reference that will tell
you how much fuel their 315 engine burns at various revs, but I can
assure you the starting point at max is going to be about 19-20 usgal/hr.

Assuming the fixed pitch props are correct, then at 3400rpm those
engines would be making 160-175HP (yes that's right around 1/2 max HP) &
given the known consumption of marine diesels it's easy to predict the
fuel usage @ 9.9 usgal/hr X 2 = 19-20 gal/hr. Honestly can't you see
even from this that the original claim of a 6gal/hr cruise & then an
11gal/hr max is just hopeless BS???

"Equipped with a Yanmar 315 hp engine she will cruise effortlessly at 14 knots
burning less then 7 gallons per hour. The Downeast 35 is safe, seaworthy and
spacious."

I have always had to contend with this in this NG you actually think if
enough people repeat a lie it somehow becomes true, from the OMC dealers
not knowing how their own engines idle, to them not knowing then
repeating the same lies they were given by OMC as regards Ficht, to this
endless nonsense about diesels. It's simple HP for HP you'll save about
20% of the fuel petrol vs diesel.

The above by the way, is a 13,000 lb boat. Or almost twice the weight of the
True World and draws over a foot and a half more water with a full keel.

Dealers & other selling spruikers are the a..holes from whence the BS
comes!!! From there it's spread over the magazine pages by advertising
chasing inexperienced magazine writers, then inexperienced non boaters
like you spread it word of mouth, soon people think it's right; so
what??, it's not. Things like this are not resolved by a show of hands.

The proper diesel manufacturers publish the fuel consumption figures &
it's a very competitive business even Yanmar are silent in this because
they know any proper fuel graph would stop the deception.

"Capt." you are clearly not a boater at all, you just swallow the
magazine nonsense then repeat hoping nobody will ever ring the bell, the
bell has tolled for thee.
