[C320-list] What is top RPM ?

[BAdams3491 at aol.com]

Max rpm is 3600, Yanmar says to cruise at 80% of that...around  2800/2900.
 
A dirty boat bottom will affect engine rpm.
 
Here's a web site to a Yanmar forum:

I  thought a dirty bottom would affect overall boat speed not RPM
The Prop is  the orginal that came with the boat.
