Nick, I was looking at Southern Automotive's website, They manufacture a lot of the military alternators, and most of the alternators are not sealed. They have to have airflow to keep cool. The old generators did not produce enough heat to need the forced cooling but an alternator needs fan forced air to survive. Look at a 60 amp military alternator and you will see it is not sealed. Like I said several times, I ran normal ford and Chevy alternators under water for many years with no problems. These were vehicles that I drove every day so they got a lot of use in addition to being submerged. You ought to try it before you spend any more money or time on exotic setups. They probably are not going to charge while under water but you are not going to be driving under water for miles either.
