Subject: Re: TWL: how much power

<<(51' / 35,000 kg
(78,000 pound) / 94 hp). The Mitsubishi-Engine is a
very slow running
heavy-duty version ( 1,500 RPM max.) and the power
output is rated
"continuous".
I am not quite shure, weather this engine matches to
this 'heavy metall'. I
would prefer about the double hp.>>
Winnie the Pooh is 33,000 lb, 39'LWL, and has a John
Deere 71 HP continuous rating engine (rated at 2500
rpm). Our normal cruise speed is 7.5 kts on 1.5 GPH
at 1800 rpm, using about 27 HP, top speed is 8.8 kts
at 2400 rpm, 4.3 gph. I would feel very comfortable
with a smaller engine, say 50 hp, which would get
slightly better fuel economy and probably be happier
in the long run, running at a higher % power output.
You can ratio these numbers to your situation. Please
keep us informed about your purchase.
