    Re: Corrosion problems specific to Bravo III outdrives

    Water bird. I made the replacement of the outdrive that was on my boat contingent with my offer. I made the offer prior to official inspection, but contingent on: if the outdrive only needs annual service, I'll take it.

    When the boat was hauled out and the O/D was corroded completely, I requested the PO replace it. He did.

    I'll try and find the link here of that thread.

    There are lots of articles about this issue on the internet.
    The best way to protect the BIII drive is to follow the maintenance instructions, use the correct anodes, change them well before they are half gone, keep the drive well sealed (painted) and inspect it on a regular basis.
    Even doing this, I would avoid keeping a boat in the slip in salt water if it has BIII drives.

    That's easy to say sitting in Wisconsin. LOL

    Keep your outdrive in the down position when not in use keeps the water out of the pickup and coat with corrosion x or some other heavy duty anti corrosion stuff.

    The surveyor will be able to identify the corrosion issues and give you an assesment. Just make sure he pulls the props to check the condition of the bearing carrier as well.

    I would also be concerned about whether the Mercathode is operating properly (you have to get readings while the boat is in the water) and the bonding system is OK and does not have any issues because that will also cause problems. Ask the surveyor if he checks either of these things.

    You make a great point Dave.

    We have all likely had different experiences. These experiences would cause us to say to a surveyor Make sure you check X

    Maybe we should make a list of what we feel a surveyor should check.

    Also, at what point do you tell the surveyor to stop. What I mean is this: say you are buying a $20,000 boat and in the process of the survey its discovered the fiberglass has a significant delaminating issue around the hatch. I would not want the surveyor to continue. Id want them to stop, pay them for what they have done and withdrawal from the offer.

    I have tried to search the internet for a marine survey form as a starting point but have come up empty.

    None of these are a good starting point? http://www.google.com/search?sourcei...rvey+checklist
