    Corrosion on drive

    ACP = Active Corrosion Protection -- this is an impressed current system. Much like the MerCruiser Mercathode system -- but a little smarter. Yes the 2 S.S. props can cause a problem, MerCruiser had terrible trouble with the Bravo 3 and they had to add some more anodes along with making the...

    Corrosion on drive

    There are a number of tests that should be done. There are a few types of corrosion. Given how little time the O.P. says this boat has spent in the water ——- I would be looking at stray current corrosion. Does this boat have ACP installed?

    Corrosion on drive

    There is electric power going through the drive, this is what is causing the problem. I’m not sure what you mean by “earthing cables”. Boats have two systems, the grounded and the grounding, sometimes called the battery negative and the bonding system. These two systems are usually connected...

    Corrosion on drive

    I should modify this to read. Yes I've seen this more then a few times. It was ALMOST always an issue with the boats wiring. A couple of times it wasn’t the boat, next door neighbor of a customer had an “invisible fence“ installed for their water loving dog and had the wires ran down into the...

    Prop spins easily, but not freely

    The are a few different Volvo drives. You don't say what one you have, but if it's a "SX" style. They do have some bearing preload when new and don't spin freely until they have a lot of hours on them. The service manual covers how to measure it and how much it should have.

    Sx-m bearing cover with stripped dipstick hole

    I have replaced a few of these that the customer tried to helicoil because they were cracked and leaking. Also replaced a couple that were cracked but hadn’t been helicoil. A dealer see’s these because a new cover requires shimming and that scares some customers. My point is that you should look...
