I am about to start replacing the swivel pin assembly on my 1990 115. I have purchased a complete exhaust housing with swivel assembly in perfect shape. My plan is remove lower gear housing then pull powerhead. Move the power trim/transom bracket to the new housing/swivel and reassemble.
Problems: I am trying get a lifting ring and have been steered toward a threaded eye bolt yet I look at the diagrams for the fly wheel and it looks like it should be a ring attached by machine screws. Other than the exhaust housing/powerhead gasket and replacing the impeller is there anything else I should be looking at?
Any of your insights or experiences with this would be hugely appreciated, Doug

Use the lifting eye that threads directly into the flywheel.
Sounds like you are on the right track.
Replace the fuel pump diaphragm kit and the oil injection check valve and you should have a good motor there.
