Default 2014 Yamaha F90LA Bearing Carrier Puller

I managed to bend the prop shaft on my 2014 Yamaha F90LA outboard last week. The lower unit has the bearing carrier with the large ring nut and the 4-vane support design. The carrier is really stuck in there (saltwater engine). Can someone recommended a bearing carrier puller that will work best for this unit? I tried using a couple of 3/8" steel j-hooks with a bar across the shaft, but no luck.

Can't recommend specific puller for your motor - I used a harmonic balancer puller from NAPA. Once you get a puller that fits:

How about some gentle heat on the aluminum casting that the bearing carrier rides in? This worked for me along with gentle tapping around the casting/bearing carrier interface while under tension with the puller. I also had to buy heavy duty threaded rod from McMaster/Carr in order to not deform it with the puller.

Gentle heat, gentle tapping, and the occasional turn of the screw on the puller. Make sure to grease the threads on the main puller rod. Patience is your friend.

Good luck!

I made a puller that was 2 bolts welded together that threaded on to the prop shaft and then welded on a bolt that fit my slide hammer. Attach the prop shaft to the slide hammer using the homemade attachment. Make sure you remove the thread ring that is holding the carrier in place. Put the lower unit in a vise and use the slide hammer to remove the carrier. I made a few J hook type pullers without success before using the slide hammer. BTW this was a 1991 50 hp 2 stroke yamaha that I couldn't purchase a puller for.
