Re: Big Twin Lower Unit Reseal Question

On those old gearcases I normally use no more than 5psi and usually a bit less.
Now…..on your original post you have mentioned shaft seals more than once but you have not mentioned the shift shaft O-ring as part of your re-seal.
Sometimes we get ahead of ourselves around here without asking the basic questions.
Have you changed out the shift shaft O-ring? If not, that is pretty much the main offender as far as a leak goes. Needs to be changed. You can verify with soap and water and a bit of pressure.
