Just thought I would provide some information that might save someone hours and days of internet searching.
I had to replace my sen-dure model 1850 heat exchanger but all the searches I did came up with literally nothing. I purchased a newer model heat exchanger but the hose configuration was quite different. After talking with someone at my marina, he sent me to a local marine store hoping they may have a used one. Well they didn't have a used one but he started showing me a catalog with the number I gave him of the newer model. As luck would have it the previous page in the catalog had the exact same heat exchanger I had to replace. Instead of being a sen-dure unit, it was a Lenco unit. So the old sen-dure 1850 is now a Lenco LE1850. Sure saved me a headache redoing all the hoses and connection.
