[C320-list] Boat Speed

[Mark Schiesser]

Paul, 

I am glad to see your question as I have owned mine for 3 years and
experience the same thing.  My wife keeps telling me we need a bigger
engine.  I keep telling her "I knew you were a closet power boater"  
Your boat is a 27 hp or 18 Yanmar?
I have a prop that does not fold as such but twists to a neutral position.
I noticed while inspecting just prior to going in the water this year, it
has an adjustment to allow for attack angle adjustment.  It looks to be
adjusted significantly to one extreme.  I did not have an allen wrench with
me that day to play with it some to see how the adjustment would affect it.
I am also looking forward to the answers you get.

Mark

I just purchased my 320 several weeks ago and am concerned about the boat
speed while under power.  I have a 3GM30F and cruise at about 5.4 knots at
2700RPMs.  It seems slow to me.  I am currently cruising with other boats, a
(hunter 28, beneteau 331, and an Irwin 38.)  They all cruise easily 6 knots
at 2700 RPMs and I can't keep up.  I have a 3 blade prop.  Could I be under
proped?  What is the cruising RPMs for the boat?  I have no ID plate on the
engine block.  I assume it is rated for 3400.
