After testing that our engine reaches full RPM (over 3K) in neutral,
but in gear only reaches 2K, we've decided that the most likely cause
is too much prop. We currently have a 13RH10 2-blade prop. Any
recommendations for what is "standard" prop for Catalina 27? I would
guess a 13x8 tops? Also, any ideas for which particular prop to buy?
Don't want to shell out big bucks for Maxprop, so thinking of going
with campbell 3 prop? Thoughts?

Thanks.

If you're a long distance cruiser a maxprop might be a good idea, for you
though it sounds like a waste of $$$$. You might try this instead-

$750 for my Catalina 28, better performance in reverse, 1/2 kt. of
additional speed under sail, when the wind dies you can still sail rather
than motor. Folders actually have less drag than feathering props. You
contact the distributor with your boat model and engine and they tell you
what size you need. You can also get a 3 blade folder if you have to have 3
blades.
