I need to replace the swivel pin bushings on my 90 hp Optimax as they are extremely worn and are to the point to where it is getting hard to steer. I have read in the service manual on what to do and I understand it is a lengthy process, pulling the powerhead and such, but is there anything that you all may suggest to replace at the same time or any heads up on anything particularly difficult to watch out for? Thanks for your help.
