I installed a Beta 38 hp engine in my 30 ft trawler. I noticed the heat exchanger zincs were consumed in just a few weeks. I inquired from my local Beta distributor if he had any idea why this was and he gave the expected response that I must have some electrical connection wrong. I spend no time in marinas so he couldn't blame it on stray currents. Recently I learned from another site that many people with Beta engines have this same problem and have found no solution. I wonder if any members on this list have Beta diesels and if they have problems of longevity with the heat exchanger zincs. Richard P

We're running a 42 HP Westerbeke diesel and replace zincs about every 4 weeks. We run fairly consistently, though when we we sit, we sit for only 2-3 days at a time. I don't recall what our time frame is for replacing zincs when just sitting for any length of time. I've considered adding an inline zinc housing. The inline zinc housing that I'm familiar with, and have installed in several boats is made by Sendur, and uses a zinc of approximately 3/4' x 2"; they may have other choices. I haven't done so because changing out our zinc is easy and the cost for the replacement zinc, sans plug, is only a coup. We do carry 6-8 extra zincs in order to always have sufficient quantity should be be in areas where the zincs are more problematic to obtain. *Rudy & Jill Sechez * *BRINEY BUG-a 34' Sail-Assisted Trawler * *850-832-7748 * *Annapolis Md Chesapeake* > >
