2021 Suzuki 150hp, 175hp and 200hp Lower unit failure analysis and rebuild.

2021 Suzuki 150hp, 175hp and 200hp Lower unit failure analysis and rebuild.

I’ve seen at least 7 of these lower units fail abruptly with under 400 hours on them.
Every single time the pinion gear has been completely annihilated in one way or another.
I’m curious if anyone else has had issues with these 2021 and 2022 Suzuki DF150, DF175 and DF200 lower units?

Here are a few of the things I used in this video:

Torque adapter: https://amzn.to/3MnGNH9
Bearing carrier puller: https://amzn.to/3VYDZDa
Timken 6010-ZZC3 (carrier bearing): https://amzn.to/3MjI81j

Some of the OEM parts needed:
57300-96850 Gearset
57500-87861 Reverse gear shim set (Clutchdog Side)
57500-87852 Reverse gear shim set (Bearing carrier side)
09181-60005 thru 09181-60013 Pinion gear/ Driveshaft shims (Various sizes)

I’ve got 5 rental boats that just so happen to be 2021 models. This is my third season with them and I couldn’t tell you how many of these I’ve had to rebuild, yes some were due to renters hitting rocks and such but I would dare to say each one has been rebuilt at least twice if not three times. And at $800+ per gear set plus other parts it isn’t cheap, not including down time. Thanks for the video, I’ve been saying that there must’ve been a factory or material issue. I had 2019 models before these and the only time I had an issue was when a renter hit something in the water and then it was only a bent prop shaft. Never had to change a gear set until these ‘21 models.

Thank you so much for making the video. I have one that needs rebuilding. Do you happen to have the number for the Timpken barons?
