Ok, we all know the disease cannot be cured...

This coming weekend myself, Jr. and friends are on a mission
to recover a 67 Bowrider !!
My question is on the outdrive in the pic. Can this be manually
released to raise after we dig it out ??
It is over an hour ride from Area 442 and do not want to forget
any and all tools for proper extraction !
Lord forgive me please...
