[Alberg30] Universal Diesel Power

[Mike Lehman]

Roger,

Engine HP is usually rated at full throttle, in your case probably 3600 RPM. 
At cruising speed your will not be as far up on the power curve. A 
three-blade props helps because the is always one blade "cutting", so it is 
smoother and more consistent. The prop needs to be matched to both the 
boat's hull design and weight and to the power curve of the engine. Ideally 
you should run a deisel under normal cruising conditions at 75-80% full 
power. The worst thing you can do to the engine is "labor" it with too low 
RPMs. The 18HP 3-cyl diesel is close to the ideal engine for the boat.

Albergers (no fries);

I would like to get into the fray RE diesel engine power.

Mahina (#148) has a Universal 18 diesel which I believe develops 14 HP. (So 
why the heck didn't they call it the 14?  Life's mysteries abound.)    It 
has a 2 blade prop, automatic bleed (that I do not know how to work) and 
about 500 hours run time.  (Why don't engines ever walk?)

I have powered in calm seas in at 5 knots plus with fuel consumption under 
1/2 gal per hour (11 gal tank).  I have also power sailed upwind 
successfully in 1 to 2 foot seas but have not been out in high winds and/or 
seas.  Can anyone with this motor report on it's performance in these 
conditions?  Any opinions on weather a three blade prop would strain the 
engine too much?  Does anyone know what stocks will appreciate over 30% in 
the next week?
