Water pump question 2008 60hp Merc 2 stroke - gear ratio

FiveStar · Jul 19, 2016

Hey guys, I've got a 2008 60hp sn# 1b729008. I notice from the parts lists there a are two water pump repair kit options. One for 1.64 and 2.33 gear ratio.

My motor is not a big foot, can anyone tell me which one I should buy?

Since you're sure you don't have a bigfoot gear housing then you would need the kit that fits the 1.64 gear ratio as the bigfoot is listed as 2.33:1.... Also there sometimes is a sticker on the lower unit gear housing area that may indicate the gear ratio too.

1.64:1 = (GEAR HOUSING ASSEMBLY, Complete -3.44 Inch/87.37 mm Torpedo Diameter) https://www.marineengine.com/parts/mercury_marine_parts/sn/1B729008/1060412FD/11413_240

2.33:1 = (GEAR HOUSING ASSEMBLY (Complete) (Long)(Bigfoot)
