- Bruckmann 29.9 Blue Star
Hi folks!
Just looking for a reality check! I have 3 seasons in New England on a 2001 Bruckmann Blue Star 29.9, twin Yanmar 6LP-DTE with 1-1/2" shafts with 17"x24" bronze propellers. There are no bonding cables nor transom zincs, so the engine zincs and shaft zincs are it, and the engine zincs are changed annually and 50% remains, but the shaft zincs are a different story.
The first season I ran the boat with the shaft zincs (2 @ ??lbs) that were installed and they were gone by August. 2nd season I ran X-7 zincs (2 @ 1-1/2lbs) and they were done when I hauled the boat in October. Last year I ran 1 x X7 and 1 x X7H on each shaft (4-1/2lbs), only a partial zinc left on each shaft...
As I prepare for this season I plan on running 2 x X7H on each shaft(6lbs).
Does this seem excessive to those of you that have a 30ish fast trawler powered by twin diesels?
Thanks for your thoughts.
