Probably what, 2-4 times better than the Navigator?

Slightly over 4 times, if I recall. At cruise (19kts) the Navigator
burns about 26 gallons per hour (combined, both engines) which is not
too bad for a boat that probably displaces about 42,000 lbs loaded up
with all our junk. Based on some reading at Trawler World and similar
Websites I understand the little diesel in the GB burns around 3 gal/per
hour at 6-8kts, rising rapidly to 12 gal per hour WOT at a
wind-in-your-face 11-12kts.

If I'm reading this thread right, you're looking at a Lehman 120 in a
1982 Grand Banks 36?

It will never see 12 knots unless being towed by the USS Harry Truman!
Your top end will be in the neighborhood of 8.5 knots. It will burn
approx 1 gph at 6 ~ 6.5 knots, 1 1/2 gph at ~ 7, and from there it goes
up very steeply.



I have not met the current owner yet, but from dockside chatter I
understand he used the boat quite a bit. It has been all around the
Great Lakes, East Coast, Florida, Bahamas and even Cuba.

That's good. A boat that is used regularly is generally a much better
deal than one that has been sitting.

There are a few quirks about the Lehman I can tell you. The original
engine supplier, Bob Smith, is still in business (American Diesel,
Kilmarnock Va) and his son is extremely knowledgeable about these
engines. No problem there.

Don't forget about the transmission, either. At a very minimum, get an
oil sample analysis from both engine & transmission.

BTW the engine driven hydraulic stern thruster is a half-measure, a
kludge. IMHO as useless as mammary glands on a bull.



We haven't heard a response yet to the offer. Assuming he is serious
about selling it should be acceptable as it was close to his asking
price. We'll see.

There's a *lot* of boats out there for sale, assuming your wife doesn't
have her heart totally set on this one.
