Ok, I'm going to pull this quote apart....
Kit-Transom seal. There is a whole bunch of parts in that kit that you don't need. All you need is the uni joint bellows and the gimbal bearing. Those 2 together are $230.
Labour to remove the drive, pull the gimbal bearing, bellows and old shift cable, and replace takes 4 to 6 hours. Let's call it 5 hours. The quote makes it $200/hr. Even here that's double the going rate!
The uni joints. The quote is for a complete yoke assembly, which involves pulling part of the upper housing apart. To replace unis, just replace the unis. They are $80 each, and it takes less time to do 2 unis than pulling the drive to bits. That then also means the seals, nuts and washers associated with the stripping aren't needed anymore.
Shift cable. The quoted cable is non-genuine. Do yourself a favour and insist on genuine parts. They do cost a little more initially, but are better value in the long run.
Trim senders. I have no idea why there is a $203 item there (18-7634), because the one below it has all that's needed (both sender and position switch)...
He's also quoting a non-Merc oil. Not recommended for the bravos. Use ONLY Quicksilver High Performance Gear Lube. And he's only quoted for 1.5 quarts. A Bravo needs around double that. Unless he only plans on draining enough to open the top housing and refilling it. :facepalm:

Just googled that sierra 18-7634, and it's a trim sender, for an OMC!
