Dude, thanks for the awesome instructional videos. I have a 2005 Mercury/Mariner 25 HP 2 stroke and these vids have been a huge help. It looks like you got after it and lost some LB's and buffed up! Keep up the great work!
Really appreciate your videos. I have a 2012 -15hp 2-stroke that is getting water in the lower unit. I grabbed it in Canada, when they were getting out of 2-strokes! Everything is identical to 2006 motors. I am going to do a full water pump assembly change as per your other video. Any chance you would do a video on changing the prop shaft seal? If it is the prop shaft seal, do I just need to change the big O-ring on the Bearing Carrier? Or do I need a full seal kit of some kind? Keep up the great videos!
I have a very low hour 1989 murcury 20hp two stroke I believe I have a leak I’ve done the water pump a few times so I know how to take the lower off is there any so special tools needed to re seal the lower unit I plan on changing all the seals drive shaft prop shaft and shifter shaft they are all original and probably just old and dry not sealing well
Sweet I just got my first boat and I am poor so I do stuff cheap can I use a compressor and just spray soap water or is there a old school way to check this I just spent all my money
did this test and passed. But still get water intrusion. I heard that spinning the prop by hand while doing this test will give you a better result. Whats your thoughts on that?
Great video, thank you, one correction, the pressure needs to hold for 10 seconds (from 100 hp Yamaha Service Manual)

Do not use a air compressor you risk blowing all the seals out.
What if I discover the leak coming from around the prop shaft housing?
oil seal leak

Sounds like you have a bent prop shaft.
I have gear oil leaking out one of the bottom holes on my nissan 40 2stroke.
Whats up with that?
Drive shaft seal?
