Yes,, pulling the powerhead is no big deal, provided none of the retaining screws is rusted/corroded in place. So, I guess that is where to start…Find a good screwdriver that fits well into those screws….Using an undersize screwdriver improperly will just bugger up the screw heads making the job more challenging. Finding a good screwdriver with a hex grip on the shank to help loosen the screws. It might be easier to tip the engine completely upside down so you can get at the screws more easily. The trick is finding a good way to secure the engine in that position. Some might recommend a hammer/impact driver to help loosen the screws if they are tight, you may need heat also.
Once you have the seven powerhead screws loose, try the four gearcase screws. You are all set if all the screws loosen up without too much struggle. Go ahead and remove the powerhead screws, along with the fuel/air lines and vertical throttle rod. The powerhead should come off now. Disconnect the upper shift rod from the shift lever, remove the four gearcase screws and remove the gearcase as well..
Be careful to note the positioning of all the lower powerhead seal components, this is extremely important.
Let us know how you make out and we will go from there…D
