I aquired an older Mercury 9.9 for our fish camp up in canada. At the end of last year, One of my guys called to say the prop went out on the motor He gave me a serial number off of the motor of 7103031 or 7108031, could not read the writing. Neither one of these serial numbers come up on any of the sites I've looked at. The motor is supposed to be someplace between a 1976-1978? The only number they could locate on the prop was 9P A11 That number is also not comming up on any sites I've looked at. Can someone point me in the right direction. they told me the prop was a two blade approx 9" in Dia.

Thanks

Its possible it could be a 9.8, the cowl and much of the motor have been repainted, can't find a model number anyplace.

Hi there, Are you sure it's a 9.9 and not a 9.8 HP as the 9.9 looks to have stated in 1986 while everything below that is 9.8.

If the engine is 9.9 then here are the listed props for it.
48-42522A12 PROPELLER (9" X 9") $102.33 $85.96 1
48-17874A12 PROPELLER (9" X 10-1/2") $102.33 $85.96 1
48-42524A12 PROPELLER (SAILPOWER) $102.33

If it's a 9.8 then here is the listed props for it.
Mercury part number 48-77968A1 This PROPELLER ASSEMBLY (2 BLADE-ALUMINUM-9" PITCH) was SHIPPED WITH ENGINE FROM FACTORY and should still be available.
Some other options for the 9.8 would of been,
48-87572A10 PROPELLER (SHIPPED WITH ENGINE) MERC 9.8 $140.17 $126.37 1
67 48-47922A10 PROPELLER (9" DIA., PITCH, 2 BLADES, ALUMINUM) 8 $140.17 $126.37 OPT
67 48-47922A10 PROBPELLER 48-47926A10 (9" DIA., 10" PITCH, 2 BLADES, ALMINUM) 8


Parts catalog for 9.8's http://www.mercruiserparts.com/selectSerailRange.asp?doc_nbr=9.8
Parts catalog for the 9.9's http://www.mercruiserparts.com/selectSerailRange.asp?doc_nbr=9.9

Going by the serial number range suggests it's a 9.8.
