How to rebuild the Power Trim on the Yamaha 4.2L V6 225 250 300hp 

two tips for people following this incredibly helpful video (I just did mine thanks to this video). If you dont have the hose Mike uses, you can use a short pvc pipe over the piston and rest the engine on it to hold the tool. If you dont want to use ATF there is branded Yamaha fluid for the trim tilt system, it is part # ACC-PWRTR-MF-32 and matched what came out of mine (also F300).

your content is incredibly helpful and clear, thank you for taking the time to put these together

I tried to cheap out when I did this and ordered a 30 dollar Pin Wrench AMT0004 from amazon, absolute garbage- didn't fit well, damaged my cylinder cap and broke off two of the tool pins, i ended up ordering the Marine Tech Tools pin wrench you recommended and it worked flawlessly.

Just subbed. Not sure why I hadn't already.

9:40, funny!

okay, what pump is that?
