[C320-list] Fwd: What is top RPM ?

[Karl Mielenhausen _/)]

Joe,

I think some of the others might be being a bit harsh.

I found the Yanmar manual to be lacking in specific operating  
instructions, for example, they caution to race the engine every 2 hrs  
when operating at low rpms, but never define what low is. They do not  
include a power curve. Suggest you invest in the SELOC and/or Clymer shop  
manuals.

Based on info from other sources, including a power curve I found in some  
promotional literature on the internet, I created a fuel efficiency  
spreadsheet, which can be found here....

Bottom line is that you should be able to achieve 3600 rpm.
Cruise between 2400 and 3400 rpm. Cruising under 2400 rpm requires the  
hourly runup.
