I am wondering of the gear case from a 1965 Homelite will fit a 1970 Bearcat. My 1970 Bearcat has some damage to the skeg and I know where I can get a replacement with gears and shaft but it comes off of a 1965 model. Will the gear/clutch dogs from the 1970 fit the 1965 gear case?
'The 1961-1965 models have a splined driveshaft on both ends. In 1966 the lower end of the driveshaft was changed to accommodate a threaded drive pinion. This change did not effect the gear ratio. While the individual parts are not interchangeable, the entire lower units are, as long as they are switched as complete units. Several different bearing designs were used in the lower unit over the years also'.
if you swap the entire lower unit assy, meaning driveshaft/lower leg/gearcase, you will be fine. With the possible exception if the replacement assembly has the water pump housing with a return line AND and a feed line, swap your single tube water pump housing to the new assy and install on your motor.
Thanks for the information. There is a complete foot on EBay for $125.00 but it is from a 1965 Homelite. My skeg is ground off up close to the body but the gears/shafts and clutch dog are good, so I think I will tear it down and get a new skeg welded on, then reseal it.
The "CR" prefix in the part number denotes Chicago Rawhide. As a caution, unless the seal shells are made of brass or stainless, they are going to rust. Some years ago, I did a lot of research to locate marine seals for these engines. I can't find my parts list right now, but if I do, I will post it here. I believe the drive shaft seals from an OMC Big Twin 35 & 40 up to about 1968 will work on the homie/bearcat - and those have stainless shells. Then, I recall that the propshaft seal was from a late model Mercury 50 Big Foot lower unit. Don't hold me to that though. I did a friend's Bearcat with these seals over 10 years ago, and it is still sealed tight - and it sits on a patio boat 8 months out of the year.
