M Marine Tech ToolsLower Bearing Carrier Puller

Fought with removing a frozen carrier in my Yamaha f250 for days, making and breaking different type of pullers. With some serious heat I had it out in 15 minutes.Pros: very well designed for the application, the key are the minimum pivot points and ridged profile along with the concaved centering pin riding on a ball bearing. This keeps it pulling true on the output shaft and doesn't walk out of center.The cons: Like others have said the fit and finish is not as advertised. Mat black cheap tool finish is all you get. Not like the picture. 2nd, the quality is not a $190 tool. Threads were rough out of the box and the "pins" that attach the arms are thread too far up the bolt shank. They are threaded way too far and are now damaged after first use from the arms themselves. Even with lightly lubing the puller threads before use, there was some burring and damage to the thread profile from the stress. Next time I would use a heavy grease instead.Glad I bought it and stopped messing around wasting time, but if you are a boat mechanic I would add labor to this job because the tool is not cheap and you can expect to replace it if used on a regular basis.

I am the third owner of a 2004 Yamaha F150TLRC outboard, housed and operated on the hot, humid, and salty Texas Gulf Coast. The engine has 1005 hours on it and this was the first time I attempted to replaced the water pump and the shaft seals. The drive shaft upper bearing housing refused to move, and the prop shaft bearing housing was also very tight. I purchased the MT0016 slide hammer puller for the upper housing, and the MT0017 puller for the prop shaft housing. This after many hours of effort using work around tools. The two Marine Tech Tools pullers did a great job in a very difficult corrosion induced parts removal situation. I recommend both pullers. This was a DIY project. The MT tools are not inexpensive, but they are a great investment considering the cost of taking the job to a repair shop, and I keep the tools for next time.

Being a retire mechanic I appreciate good tools. This is the best puller I've ever used. It's designed and built to do the toughest jobs and last forever. My only criticism is that at almost $200 it's a little pricey. If it was say $125-$150 I'd say it was also a great value.

Puller arm hook straightened upon first use and rendered tool useless.Contacted company and they were very helpful with overnighting a pair of “large” replacement arms that worked on the first try with a little heat on the case.

I tried 3 different pullers with no success. This lower unit tool is the only way to go. It took 10 minutes to pull my bearing case out. I was trying for two weeks. It's heavy duty. I love this tool. I would highly recommend this.
