Our 1991 boat came with one of these https://www.amazon.com/Little-58150...iant+pumps&qid=1593353080&sr=8-12&tag=mh0b-20
It supplies sea water to both reverse cycle heat pumps, 16K BTU main cabin and 9K BTU aft cabin. This original unit still in the fight. Periodic (every few years depending on amount of use) cleaning of the impeller is all that is needed.

I bought the koolair 500 listed further up this page as a replacement pump two seasons ago, had to replace it this year. I went with the little giant 500 as that is what my ac manufacturer sells with their units.

The March pump is seawater cooled and it doesn't appear any of those posted above are. I can't imagine an uncooled epoxy enclosed pump lasting like a March would. There's a reason that they are the standard in A/C seawater cooling pumps.
That said, I've had absolutely great service from the Little Giant pumps of the proper size, but they are in no way sealed and may not be submerged. Ours (A/C & Refer) are both over 10 years old and we have been full time liveaboards for that time and the refer pump runs at least two hours a day, every day.

I have the March mag drive LC3-CP . The first one lasted 20 years. I am on second one now and the newer model appears to have a better cooling coil. The original one failed from coil overheat. I found the new one on eBay at a great price a few years back. My unit runs on dehumidifier mode when I am not there and ac runs when I am.
I just installed the Seaflo 500GPH AC pump. The spec sheet says it is "liquid cooled", magnetic drive and can be installed either submerged or in air.
Can't go wrong with that choice! As with most things, costs a little more; however, it should provide years of trouble free service.
