I recently purchased a used Nitro Bass boat with a 115hp Mercury outboard (approx 1995 model). I am running what I think is a 13"x21" (diameter x pitch) prop and my WOT are too high. From reading through all the other helpful posts about how 1" pitch = 200rpm, I have a good understanding of what I need. The question I have however is, where can I find a Mercury Prop part lookup, for example, merc part # 48-825938a47 (for sale on eBay)? I know this is a 4 blade prop with 23 pitch, but does the part number tell me the diameter? How can I tell if it will fit my 115hp merc?


Iboats has a prop-lookup, but it doesn't have the part number above? Are there any other merc part lookup webpages?


Any replies are much appreciated.
