Removed from Freshwater Mercruiser Kiekahafer Marine Engine with Serial Number 2916033. Drive shaft spins freely and smoothly and gears appear in good condition. No cracks in housing, but normal wear on housing. When I drained the oil prior to separating the upper and lower, all oil and no water came out. This indicates that the seals are good too, but I am not making a guarantee.

I am told the gear ratio is 1.62 / 24-24
