Your propeller is on closed position and I cannot see if there is the anode that should be bolted to the propeller hub. I have a flexofold also and this anode lasted only two years in Finland waters on my boat, then I had to change it. The anode between SD body and propeller stays quite intact like I see in you boat as well.

Best Regards
Kari


2 blade Flex-o-Fold comes without one... 3 blade only has it...

You experience matches to my previous boat which had 3 blade prop.

Does your 355 have a galvanic isolator? My 370 has and there are no galvanic problems so far. My Flex-O-Fold is the three blade version with extra anode. But I haven't changed it yet - 5th season. My boat has its berth at the IJsselmeer without saltwater.

Perttu, 

I'm interested to know the size of your Flex-O-Fold propeller.
Do you have D1-20 or D1-30 engine ?

Many thanks.

To me it looks quite normal for 1 season in the water.

Use hydrochloric acid and your propeller will be like new.

I take mine off and leave it in a bucket for a few hours, after that you dont need any tools to clean it.
