Ok, I have had my boat now for about two weeks and after talking to the previous owner I know the lower unit has not been serviced in quite some time. So I figure I would go at it since I have my trusty Seloc Repair Manual and all winter to work on it, shouldn't be too hard.

1987 Force 85 Outboard

Problem # 1) The only probelm I had in removing the lower unit was that one of the bolt heads holding the L/U to the upper unit sheared off. The other five were no problem. What is the best way to get the remaining bolt
out? Can a machine shop do this or do I need to take it to a boat repair facility?

Problem # 2) L/U drain plug, seems to be a small allen head bolt which is stripped. Was unable to drain the
L/U fluid at this time. Machine shop or boat repair shop to have this fixed?

Was able to remove the impeller housing and impeller with no problems. Impeller looked real good.

Problem # 3) In the process of removing the water pump body one of the bolts sheared off (darn again). Machine
shop or boat repair shop to have fixed?

Now I was able to drain the oil out of the lower unit by turning it upside down.

Now that I have this disassembled I need to locate the following items:
drive shaft oil seal
O ring for drive shaft oil seal
Sealing ring for water pump body
Shift shaft oil seal
crush ring
gasket for water pump body

I figure while its apart to go ahead and replace all of these o rings and oil seals. Where would be a good
place on line to order these? I've checked on iboats.com and was not able to locate these specific parts. I also checked on outboardparts.com and found a lower unit seal kit, but it did not list the individual seals and O rings that came in this kit (I guess I'll call them to verif
