Corrosion protection?

[Steve Miklos]

I have a bravo with a IMCO lower it has no zinc on the propshaft I am geeting corrosion after a day and a half win I leave it in on weekends.
Anyone have a solution? I recently saw an Ilmor boat were they put a zinc on the hull any help would be great. The batteries are off mercathode is on the boat.
Thanks

Corrosion where? You still have zincs on your rams and you can add zincs to the upper at the bolts I think.

I'm concerned as I have Imco lowers for this season too!!

All the other zincs are there. When I run a Mercury carrier with zinc no problem. The lower I like has an Imco carrier and I see corrosion on the upper and lower in in less than 48 hours on a brackish river.
