1975 115 impeller replacement

[carpenterken]

How or where do I unhook the shifter rod in order to drop the lower unit so I can replace the water pump?
Thanks in advance.
Ken.

The connection is at the end of two parallel bars [bellcrank], centered under the carburetors. the disconnect is a bolt, from the starboard front, midway of the bellcrank, and usually must be removed. The two parallel bars are then spread at the shift rod to release it.

It is generally easier to disconnect the cables. I like to spread a cloth under the bellcrank in case I drop anything. Old timers often take the carbs off as part of a more comprehensive maintenance schedule.

Make sure you dont adjust that shift rod once you take the lu down. The tolerances arent that big and once you adjust it, if you dont have a manual with the correct shift rod lengths, you will have a bugger of a time getting it hooked back up again, never mind shifting problems. It is much harder to get that shift rod hooked back up again, just so you know. Gl

Also a 1/4 inch drive swivel socket and about a 4 inch extension really helps.
just don't turn the shift rod while the lower is off and it should go back together easy.
I also wipe the inside of the impeller housing with triple guard grease so the impeller is lubed at first start up..

You cannot really turn the shift rod on the 1975 V4 gearcase, it has a foot that does not turn.

The top of the rod has a cylindrical barrel connector that can be turned, but it is adjusted from the seated position by no more than 2 turns counter clockwise, with the rounded connector part facing forward.
