I have a "huge" stereo in my boat and therefore the installer upgraded the stock alternator to this "Balmar" (not sure how to spell it).

Here's my question... The alternators are toasted (the installer painted them and therefore NO WARRANTY!) and I'm getting new one's (that also fit the stock engine mounts on my 525 EFI's). Do you recommend going back w/ these same alt's or is there a newer/better one.

The stereo's being run via two alternate batteries, as not to run directly off of the two "stock" batteries running the engines). I believe the issue stemmed from running the perko's on "both." So, at this point in time, since the alternators ran for almost 2 yrs, it seems everything is set up properly, just shouldn't have been running "both" on the perko's.

Comments, please!
