To sum up the mistake I made. I pulled my alpha1 gen11 drive due to an oil leak. Found I had forgot to install the passage seal between the upper and lower unit. Got an extremely stupid idea to pull the bottom seal out of my upper unit where the shaft slides through. After realizing it wasn't an ordinary o-ring I accepted that I would actually have to bring this to the professionals, mainly due to the manual saying it required a special tool (yes I also failed to read first).. Anyway here comes the "Welcome to Boating" experience. First they told me it would be $90, 30 minutes labor and parts. I thought that wasn't so bad. Got a call a couple of hours later,,oops sorry we didn't realize the drive had to be disassembled to replace the seal,, now it's 2.5 hours plus parts, around $300... So I choked that down and blaming myself for it seemed to help some. Then the actual Merc mechanic called me and told me,, hey their charging you for more labor hours than it will actually take me,, so if you bring your lower drive in i'll assemble it and pressure check it for the $300.. That gave me a good feeling that the tech would do that. Well that was yesterday... This morning I get a call from the girl at the desk in the service dept saying it failed pressure check (wouldn't even hold 5 psi) and the seal somewhere around where the drive shaft goes in is leaking (not sure of the exact seal). I asked didn't you just have all that apart? Answer was yes but you didn't tell us to put new seals in it.. You would think common sense would take over,, or at least call and ask if I wanted them replaced then if they leaked it would be on me not them.. Sooooooo another 1.5 hours labor and the total is well over $500 to replace one seal. I suppose I could look at it in respect to I could have dropped the drive in, sucked some salt water and ruined the drive... No that doesn't make me feel better.. Well this last call the tech now says the u joint is corroded and that's what is making the seal leak. Which makes sense because I can think way back when I first pulled the drive and there was oil in the bellows (most likely from this seal).. Any way new drive shaft is over $500,, new grand total is over a grand now.. Told him to clean up the yoke and put it together,, worst senario is I watch the reservoir closely... Hey does boating get more enjoyable when the boat is actually in the water???
