I have used the Surge Guard 67050 unit on our boat for over 5 years with good results. This unit has a 2 minute countdown after a surge to allow sensitive electronics like the AC time to rest before power is restored. I also like the high/low voltage and reverse polarity protection.
Unfortunately our unit gave up the ghost a couple of months ago and it appears Surge Guard no longer makes the marine 50 amp unit. I was at Camping World yesterday and saw the Surge Guard 50 amp RV unit on sale. It has all the same features just different plugs. As much as I hate to do it it looks like I'll be making marine/RV jumpers to make the RV unit work for us.
If anyone knows of a similar marine protector with the same features pleas point me in the right direction.
