Asking an hourly worker at a place like Autozone to get marine parts? Good luck! The statement "a deer in headlights" is an understatement. If it's not right there on their screen, forget about it. It's like asking a McDonald's cashier to manually make change! Now, some NAPA stores can help, though. But even that's hit or miss.

A local Mercruiser shop can help you. They can figure out what you need based on the year. FYI, many things on a sterndrive engine are "marine" specific and are specifically designed to be "ignition protected". Meaning, using automotive parts can make your boat go BOOM. Plugs and wires are fine to swap - cap is not. Alternator, starter - don't even think about it.

Dont forget to check/replace the impeller for good measure. And, absolutely check the condition of the bellows - unless you don't mind the possibility of your boat sinking :)

You checked the impeller? How was the wear plate?

It's a little hard to follow what you are saying - can you re-read/add punctuation/capital letters/etc? "Outa" stern drive... what is that? "Out of the sterndrive?" Where?

"Outa plug hole"... same thing... huh?

Hi Dennis,
Sorry for the thread drift. I'm a new GW owner and hoping you can help. How do I check the bellows? I have both motor and outdrive out of my 84 overnighter so there's clear access. I'm just wondering if it's more than a visual inspection?

Thanks in advance,
Bob

It's been a month and half and haven't heard back from the OP... I think you're safe! :)

Yup - visual is pretty much it. They should feel pliable with no cracks. If they're getting "shiny" looking, that's another indicator that it's time to replace. On the other hand, if you don't know when they've been done last... I'd definitely go ahead and replace them as long as you've got things torn apart. Might as well start fresh and you've already done all the labor.

Don't skimp - get the Mercruiser brand. From my experience, the Sierra (or others) don't seem to last as long.
