Installed this to replace a separate float and bilge pump combo in the small forward bilge area of a 27 ft Boston Whaler. Read reviews of competition and decided to go with this unit for the 1000 gph with 3/4" hose outlet. Also the other selling point was the detachable hose barb in either straight or in my case 90 elbow configuration. Much easier to service by unscrewing the hose barb attachment from the pump than trying to remove the durable hose in a tight space. Also comes with both a rubber washer or rubber check valve insert for the fitting that can be changed to either configuration.

So far so good, automatic sensor works great and water drains to a desirable level. Pump does not auto cycle as some other pumps do (which I didn't want) and works on two sensors shown in picture (small circles). Boat sits in the water 24/7 and I have larger pumps also in the main bilge. If I have any issues I'll update this post but after a week on the water, lots of FL rain, and plenty of cycles this unit hasn't missed a beat or malfunctioned in any way.

Wiring is simple, one for fused hot, one for manual switch, and one for ground. The manual switch on my helm lights up when the auto switch kicks on if anyone was curious about this unit.

Testing the auto switch hold your fingers over both sensor circles for a few seconds (it's not instant so don't think it's malfunctioning) for it to kick on. I also cycled it with water multiple times just to be sure.

Make sure you leave 1" of space from the sensor circles to any object as noted in the instructions to prevent a false detection. Plan for this during your installation measurements.

This is the second Johnson pump that I bought for my Boston Whaler. I had good success with the first one but have been having problems this time around. The pump worked fine for a month but refuses to turn on now. I need to use the fingers contact start to get it to pump at all. Really defeats the purpose of having an automatic pump.

Update: I can't turn it on at all now. Time to buy a new pump other than Johnson.

I installed it yesterday. Yes, proper wire connections. My old one had failed--on/off sporadically and not enough force to expel the water. This one was dead out of the box. I tried the two finger test but didn't work. I put it in and filled the bilge with fresh water and... nothing. What a major pain! I'd give it no stars if I could.

I’m using this on a whaler super sport that is an open deck. There is not a hole for the bilge pump, just the flat deck. This pump doesn’t turn on until water is over about 2.5 inches deep and it turns off sooner than I would like. So is still a lot of water sloshing around. It is functional though, and is still working a year later.

i went through two of these units, never worked properly.. one would never shut off , draining the battery, the other wouldn't pump properly...

Doesn't pump. Brand new out of the box... won't push water out of my bilge. Disappointed.

Working well so far, 2-3 months in. Built in float switch made installation easier.

time will tell whether this pump will out last the rule pumps.
