    What's this "rock" on the back of my sterndrive and is it supposed to be there ?

    It's in fresh water. Seems like aluminum is the way to go. What tells you that it needs replacing? From the bit of reading I've done it looks like it's supposed to corrode away but the one I have actually looks larger than the ones on that page and more like a rock. What's all over it?

    What's this "rock" on the back of my sterndrive and is it supposed to be there ?

    Thanks for the info and for moving it! Are these generally easy to get? I noticed this today and the boat is scheduled to go into the water tomorrow . This seems like a difficult thing to install and replace while the boat is under water right?

    Rust-oleum marine or can I use any (or some) of the spray cans? I haven't been able to find the marine Rust-oleum around here. I don't think I've sanded down to bare aluminum based on the pictures, maybe a bit on some edges. Thoughts?

    How should I go about painting/restoring these two sterndrives ?

    Oil Change and Gear Oil Change issue . Can you help ?

    Oil Change and Gear Oil Change issue . Can you help ?

    No such thing as marine oil in general or no such thing as SAE 30 marine oil ? Because the first I know is definitely false, but the second I don't have an opinion on as I don't know enough about engine oils.

    Unfortunately I refilled one of them from the bottom before I learned that this specific model requires filling from the middle. Any idea on if this is a big deal ? What issue can come up? Also when I filled the 2nd motor properly, i didn't get that vacuum effect the manual mentioned. Oil...

    Oil Change and Gear Oil Change issue . Can you help ?

    What do you mean by straight ? I'm not familiar with the terms. I've had trouble finding SAE 30 marine oil. So far I've only found one product by sierra international available through amazon and it'd take a couple weeks to deliver - so I'm trying to understand other options. 25w40 and 15w40...
