Question: Is the 1200 threads 1" NPT or proprietary 1 1/8"?
Document: Easy to install. Pumps a lot of water. Haven't tried to keep bait yet. Just remember input is  1 and an1/8 inch. Out put is also. Had to buy reducers to fit my app. Other than that am happy with it.
lasted less than one season os bass fishing only worked for 12 8 hour tournaments i have had others last years
I just removed the motor and put it in the old body, no screwing or unscrewing threads. About 20 minuets with rewiring.
I decided to piece together a cheaper ballast pump kit than if you buy the Fly High Tsunami, also available on Amazon:[...]I bought this pump, soldered on a 12V cigarette plug with a long wire, purchased some 1" hose, two hose clamps, and the quick disconnect adapters, and have the same kit for about $50 less.
I bought two to replace old Attwood A750 pumps for 2000 Air Nautique ballasts. Note the inlet lengths are 3-1/2&#34;, which is not stated anywhere in Amazon's product description. Attwood makes 4 different models with different inlet lengths/wiring. This is the 4650-1/4650-7 model (per Attwood's website).
So I'm happy with the product. What I'm not horribly happy with is that the output diameter was not clearly stated on the discription of the product. So I was not able to connect it with standard sized pipe fittings. I had to hack it and put a 1 1/4 coupler and then downsize that to a 1&#34; fitting like the thing should have come with to begin with. Aside from that the pump works as it should. Moves water from the bucket to the clean up sluice.
works well
these pumps have a short life for me but work great when new. boats cost cost cost well you know or will soon discover.
these are not as good as rule pumps but they are cheaper and you get what you pay for. if dont mind changing them out every year or so this is the pump you want
the unit includes a hose adapter that can be turned to various angles got the 800 gph for the retail price of the smaller 500 gph shipping and taxes included. Even cheaper than ebay
Answer: no
