Hi,

I have a 60hp mariner. 3 cyl. serial 6429644. ordered all bearings and seals from boats.net, and a few parts do not fit, although they are correct based on the engine serial #. looks like the lower unit was swapped out at some point with one of a different vintage.

the # cast into the lower unit between the water pump and trim tab is 1643-4930. i googled this and it appears to be a 1974 vintage.

i need the drive shaft timken bearing that is directly beneath the water pump

a complete water pump kit with the drive shaft seals

and the last seal on the prop shaft. both on this unit are the same OD, and the one i received had the stainless housing and fishing line cutter and will not fit because of the larger OD.

can anyone help to steer me towards the correct part #'s?

Thanks,
Mike

Unfortunately without know the origional motor information, finding parts will be very difficult.
