[C320-list] transmission ratio

[Paul Adison]

I have pulled my prop in order to have it repitched.  I believe that  
it is to flat.  I am able to run my boat under load at 3800 rpm which  
is higher than the rating of the engine.  The prop shop has told me  
that by adding a 1" pitch to the prop I will be able to reduce the max  
rpm to 3600 which is the rating of the engine.  This will add fuel  
efficiency and increase cruising speed at the same time.  Does anyone  
know the transmission ratio for the yanmar 3gmf?  The shop would like  
that information before starting work.  I know it is on the  
transmission itself up I am not near the boat.
