Hi all recently i got a K&B 3.5 lower unit short skeg with 2- #8574 prop shaft assembly's the non threaded one's that you have to seperate the 2 lower unit half's to install the liner flex shaft and prop shaft. for the liner i will make 1 from brass tubing from the article in Oct 2001 RCBM magazine? My ? is i would like to install some sort of grease nipple or oiling port as im not willing to dismantle the lower unit every 20 runs. Where is the best location on the lower unit to install this set up ? Do i use grease nipple or oil hole ? for my newer lower units i use Mercury 2-4-C grease ? What is the best method to achieve this set-up ? What would be the best lubricant for this set-up ?What years would K&B have manufactured this type of lower unit ? Regards Andris Golts.
