Good quality

Awesome.

Replaced another brand blower with same flange size. This blower only draws 5 amps running, about 7 amps when starting. It is quieter than the old one and moves more air. I'll replace my port blower with one of these when the old one fails.

I was drawn to this blower for the price and "flex mount". Well, had a couple let downs, but was still able to get them installed, just not exactly how I had hoped.
First warning was that the wiring coming out of the fan motor is not tinned copper. Its plain copper that they tinned the ends on. So, immediately this is not a "marine grade" item. I removed the wiring and installed marine wire.
Next, the "flex mount" is not flexible. What you see in the picture is the only way you're able to mount the fan. I was under the impression the mounting foot could switch to different housing screws to alter the position but nope.
Finally, the 4" output is the same size as 4" tubing. You need an adapter to get the two to mate up or you can do what I did and loosen the housing screws to allow the blower exhaust hose to slide into the opening. Problem with this is the housing doesn't want to completely close back down on the hose. I installed a worm gear clamp around the housing so I could safely tighten the housing back together. The plastic was not happy about this and I wasn't able to get a complete seal, but it was close enough.
The good news: the blower is whisper quiet and moves a good amount of air. The price is low for a reason, as most Seaflo stuff seems to be. It has a couple year warranty but who knows if they'll come through on that.
I recommend this to weekend warriors and fresh water boaters. Commercial or heavy use saltwater boats not so much. Also, these are not ignition protected blowers, so no gas engine boats!
