Prop?
 

Hi

I have (like many others) a question on what prop to buy for my MX20C -92 equipped as follows:

Penta 305
OMC Cobra

Iam quite new with this type of boating, only had smaller boats with outboardmotors... I found myself trying to understand how to find the right prop for this boat, all the technical numbers and angels and so on just makes me dizzy. Can someone please give me a hint on what type and size to buy?! It would be nice to finally let this baby se some water! =)
