Shaft needs to be removed.
It is not a major job when talking about it . It can turn into a major job when doing it. The steps are easy Pull prop, disconnect engine shaft coupler, remove tapered shaft coupler, remove the packing nut, slide shaft out of keel extension, remove cutlass bearing set screws, use slam Hammer and inside Jaws to pull cutlass being out of shaft tube, inspect the shaft for wear and true. remove the packing housing and hose, inspect, clean up, replace the hose with new install housing with repacked nut leave loose, press new bearing in tube, install set screws, install shaft, coupling, prop, align engine, lightly snug packing gland, launch boat adjust packing. All easy steps ???
Not really the shaft coupling is a taper fit, the room between the engine coupling and the packing gland housing is tight. Breaking the nut loose recessed in the coupling can be challenging then popping the coupling off the shaft can be time consuming. If this is the first time it has been removed. The packing nut can be an issue if it has not been exercised recently. Removing the set screws in the shaft tube can be difficult if they are corroded or damaged.
Working on Ranger Tugs and Cutwaters can be challenging. The room in the compartment is tight and you will be working upside down in tight quarters. If you do it plan on spending some time doing this project. If you pay a marine service facility plan on paying $$$ for Labor. Before tackling this job with the engine in the boat I would get pricing on pulling the engine, replacing the motor mounts, installing a dripless packing and having this job done with the engine out of the boat. This would be a good time to inspect the bilge, replace pumps, paint the engines pan, replace all the hoses, Water pump and belts all things that are challenging to do while the engine is in the boat. I would also have the engine bed inspected. Fluid motion uses wood for lagging the motor mounts to the bed. The wood in many cases is rotted because of poor sealant when the lags were installed.
The job in general is easy when talking! Doing it right and knowing some of the issues that may come into play change easy to hard and expensive. You may get lucky and it is easy no issues. Knowing that there could be road blocks will prepare for the worse. Best case $3000.00 worst case doing it right and pulling the engine and replacing mounts, packing, hoses, belts, pump $8000.00 to 10,000.00. A friend and fellow TugNut had the cutlass replaced in 2020 the right way pulling the engine replacing mounts, packing , shaft inspected, belts and hoses cleaned bilge and repaired engine bed and it cost him $6000.00. Prices and Labor has gone up since then. His boat was well maintained and it came apart better than expected. He was lucky but he also had a clean well maintained engine compartment.
Good Luck with you boat purchase.
