I just purchased a new 2005 Mercury 90HP 2-stroke outboard to replace
the 40HP engine on my 20ft pontoon.

The new engine did not come with a prop, so I am seeking
recommendations from the group.

I have not yet talked with a local Mercury dealer. I purchased the
engine online.

Thanks for any feedback that you can provide. I am interested in what
top-speed and the max RPM for the recommended prop.

Thanks.... Tim

A excellent booklet was put out my Quicksilver. It's called, "everything you
need to know about propellers". And you can actually download it here for
free:

If you want the address where you can the actual booklet, let me know and
I'll post the address.

Hope this helps.
