[C38] RPM Question

[Glenn R. Terry]

I have the original M-30 engine with the original fixed two blade 15"x13" (according to the 38org. specs.).


The Engine specifications for the M-30 from:

http://www.marinedieseldirect.com/universal/200157/universal-owners-manual-m-30-specifications.html

a very useful web site I might add state:



Maximum RPM 	2800
Cruising Range (Approx.) 	2000-2400 RPM

At full throttle I am at 2,000 RPM.  The engine feels like it is revving 
much higher than this.  Does anyone know what RPM I should be with this 
prop at full throttle?  My feeling is that the Tack or the sending unit 
are not correct.  Can anyone offer me a pointer on replacing these units?

Thanks in advance.
