I found this at another boating site. The only fully restored and
operational PT boat in existence.

Nice site with pictures and facts of the boat.

Omigosh.

It would probably cost less to buy that boat than to run it! :-)

500 gph? Wowzers.

From the website:

3000 gallons of 100-octane aviation gasoline (AVGAS) is enough to last
12 hours or 520 miles with engine speed limited to 2000 rpm. This works
out to about 66 gallons of gasoline per hour, per engine at cruising
speed of 35 knots. At maximum rpm, achieving 42+ knots, each engine
consumes 166 gallons (or 500 gallons for all 3 engines) per hour. (3000
gallons lasts about 6 hours at top speed!) The gasoline is held in four
750 gallon self sealing rubber-lined gas tanks. PT658 had her 2 after
gasoline tanks removed, so capacity is cut in half down to only 1500
gallons of gas.


I guess they avoided WOT. ;-)

"3 5M-2500 Packard-Marine V12 Engines. These engines are 4 stroke, water
cooled, 60 degree, V- type with a 6-3/8" bore and 6-1/2" stroke, for a total
of 2490 cubic inches of displacement. Each engine has 48 valves, 2 inlet/2
outlet per cylinder. They have a compression ratio of 6.4:1, and are fitted
with a gear-driven centrifugal supercharger and intercooler. The engines are
installed with a Holley 1685F aircraft-type carburetor, and use aircraft-
type dual magneto sparks, with 2 spark plugs per cylinder. The engines
develop 1500 Hp at 2500 rpm.Max revolutions is 3000 rpm. Engine weight is
3100 pounds. These engines were designed to burn 100 octane aviation
gasoline to achieve nominal power output."

US Navy "SO" Type Radar : This radar was fitted on PT Boats beginning in
1943 and was later replaced towards the end of the war with SJ. Both were
3000 MHz with 50kw pulse, surface search radars made by Raytheon.
Approximate range was 25 Nautical Miles. The Navy's use of radar gave us a
distinct advantage over the enemy throughout the war.

Have you seen the boat Chuck? She is just south of you in Oregon.
