The shims I'm pretty sure are unique to your install/hull/engine. If it's all well aligned, after coupler replacement, age, etc and the added shim makes it worse...it seems you are better aligned than before. Bad alignment might also explain your coupler eaten up?
Measure and if it all lines up you are good.
This is not from your boat's manual, but not sure how much this alignment instructions have changed. Perhaps use with caution? or seek a service manual for yours? Hope it helps.
The rubber piece was fine as I changed it thinking it was bad but coupler still had play until engine was better aligned to remove play.
Yip
Its hard to be in spec when your talking .05mm and sticking your head down there. I have it flat around majority of coupler at the moment with zero to little play
Re installing pump this week and fingers crossed I addressed engine alignment troubles or I am looking for something not there.
Boat accelerates great but different than before. Its hard to explain but it works!
