Propeller part numbers

[TheViking]

I am trying to identify the size/pitch of my propeller. It's a 2004 Mercury 9.9 FourStroke. I believe the part number for the prop is 48-895180A10. I can't find any site which lists the specifics for prop. Does anybody know where you can find more info on the part or decipher the part number?<br /><br />Also, the motor is attached to a 12" aluminum fishing boat. Between the motor, 2 guys, battery, gas, etc. there is about 650 lbs of weight in the boat. I was thinking about a 9-1/4 x 8 prop. Does this sound like a good match.<br /><br />Thanks,<br />Ron

Re: Propeller part numbers

The standard prop for your motor is the 9" x 8" pitch. The merc. part number for this Black Max prop is 48-828154A12. I do not know how to cross your number, but I do think the 9x8 is a good choice for starters...

Re: Propeller part numbers

I have just upgraded from a 50HP 4S to a 60 HP 4S.<br />My old prop (SS)part no is: 48-823478 A 5 11P<br />The prop on the new motor is: 48 73136 A 40 13P.<br />Both seem to be 11" diam.<br />Why doesn't the bigger motor would have a larger diameter prop? There is plenty of room below the cavitation plate. <br />The boat is a 20' Alum centre console. I know it is still under powered, but my budget wouldn't extend any further.
