Re: my prop is bleeding

Test leaking lower unit … pressure or vacuum (both recommended)

1. Drain gear oil
2. Pressurize (or apply max vacuum possible) to no more than 15 psig with air (see OEM shop manual for max for your motor)
3. Submerge in water, look for bubbles
4. Possibilities
a. Drive shaft seal
b. Prop shaft seals
c. Shift rod seal
d. Cracked casting
e. Drain/fill screws/seals
5. Repair as needed

For V4 and V6 lower units, should hold some pressure or vacuum for at least 45 minutes.

If a seal(s) is found to be leaking, inspect the shaft (prop or drive) carefully for grooving. If there is any, make sure the new seal(s) do not seat in the same place as the groove.

I realize this is an old thread but I just found it. I see in coolbri's video that water is pouring out of the two exhaust relief ports. Is this normal?

Re: my prop is bleeding

Good to know Brian, I was aware that the exhaust relief ports would 'spit water' after warm up as my '77 85hp does but it certainly does not come flowing out. Must be time to check my t'stats. Really appreciate the video. I thought mine was running good until I heard yours. Looks like carb time also. Thanks, Steve
