Products that are NOT marinized or marine grade that work

Having done a ton of research on marine vs auto alternators there are some major things to consider. Most important is that it MUST be spark protected. This is not a big deal and only consists of a felt gasket between the regulator and the alternator case. A good friend of mine (a lake power boater) blew up his 1 year old $85,000.00 Sea Ray by installing an automitive alternator. Now I don''t know if the alternator actually caused the explosion but the insurance company used it as an escape from paying off the loss. I doubt that any diesel sail boat would be harmed by an automotive non spark protected alternator but if you have a fire/explosion problem be aware that it may give your insurance company the right to deny coverage!!!! That said check out the link to my web site mentioned by tsenator above it shows how I upgraded my alternator and marinized it by adding the felt gasket and an external regulation plate. For those of you that don''t beleive in multi stage charging try visiting any golf course with electric carts and look into the system they use to charge. They all use a three stage system to keep thier batteries in top condition. I noticed a huge difference in usable amp hours when I went to multi stage charging. My first phase (if I remember my settings correctly) is 14.6, second is 13.8 and third is just aroud 12.9 to completely top it off... here is the link just do a copy and paste into the address bar...
