JAVADO 0 Report post Posted July 7, 2009 I HAVE A 2006 322 AND AFTER THREE YEARS USE, DURING THE YEARLY MAINTENANCE, I FOUND HOLES IN MY PROPS. SEE PICTURES. THE BOAT IS MOORED CONSTANTLY IN SEAWATER. I EXCHANGE EVERY YEAR ALL THE ANODES ON THE DRIVES, THE ROUND ONES AT THE BOTTOM OF THE DRIVE AND THE TOP DRIVE ANODES, THE TRIANGULAR ON THE HYDRAULIC TILT CILINDERS. QUESTIONS: 1. WHAT IS CAUSING THIS WEAR IS THIS ELECTROLYSE? 2. HOW CAN I PREVENT THIS? 3. CAN I PAINT THE PROPS WITH 2 COMPONENT EPOXY TO PREVENT THIS? 4. CAN THESE PROPS BE REPAIRED?

JRSto 0 Report post Posted July 13, 2009 I have a 302CR twin 5.7 DP engines and at the time of my last hual out for bottom and porp paint (the boat is 3 years old) I ran into the exact same situation with my props (all 4 of them). the pictures I took look the same as yours. I consulted two prop rebuilders, neither recommended repair because of the speed they run at and the proxmity to the second prop. I found a couple articles on marine corrosion which helped me locate electrolisis situations that most likely caused "my" prop holes. The articles could possible indicate electrolisis areas of concern for you. http://www.boatus.com/boattech/marinecorrosion.htm http://www.westmarine.com/webapp/wcs/store...ing-Systems.htm also www.Volvopentastore.com has a corrosion protection system you may find useful. part # 41101900 Hope this helps.
