Only the toe portion of your lower unit will have any growth on it.... that is if your motor doesn't fully raise out of the water when tilted up. Cliff 1966 13' Sport with a 1993 40hp Yamaha 2 Smoker

Make sure you have a new Aluminum Anode and if you can flush it and rinse it now and then through out the summer, you will be fine. If you use it enough - you will not have any growth on the lower unit. If you do, just wipe it off with a scotch pad and a little Simple Green. Every other summer we have the Outrage in Avalon, on a mooring....sometimes up, sometimes down. Look around the marina - you will find some motors in & some up. Sounds like you may be at Ventura Harbor or Channel Island Marina.? Have fun - The Channel Islands are a blast!

I use magnesium for my fresh water boat but I am surprised to find that aluminum is now the preferred material for salt water anodes. I learn something from this site every day. Edited by wing15601 on 05/01/14 - 7:43 AM I winter in Ft. Myers and summer in St. Joseph, Michigan. It’s now about 12 years since I’ve joined this group. I gave my 1972 whaler to my daughter and sold the 17’. Bought an O’Day 28 sailboat and sailed on Lake Michigan. Yesterday I bought a 2005 130 Sport.

Pure aluminum will not work as a sacrificial anode, it will oxidize immediately in saltwater. The aluminum-alloy sacrificial anodes have been pretty much industry standard since the 90's.

I would recommend new QuickSilver/Mercury aluminum anodes, both for the plate under the trim unit, and for the trim tab.
