Hello, I hit a log today and bent a blade. I was able to repair it slightly using a rubber mallet, but it's still not perfect and I've decided I need a spare prop anyway. The only #'s I could find on it were stamped into the side as follows.....4877346a4519p. Obviously it's a 19 pitch, but what is the diameter? I get good WOT RPM's of approx 5500 ish and decent top end speed of about 36 MPH on my 1997 Sea Ray 175 (18') with a Merc 90HP 2 stroke outboard, so I was thinking of just replacing it with the same specs, if I can find out the what they are. Any replies are appreciated.
