I installed this horn in my boat and it worked great for about 2 weeks, then it stopped working. The device is still getting 12VDC so the problem is the horn. Would not buy again.
Simple remove and replace. Just make sure outside horn cover and plastic diaphragm is not torn otherwise use a little silicon RTV to fill and cover possible salt water entry from exterior horn cover. Used on Seaswirl Striper 2600 SC. 2 leads should be color coded red and black to ensure unit is grounded on frame side to boat ref ground. Not required unless the fan is installed on metal or hull is ref to grnd side.
You will need two new screws and two new nuts, I found this was a perfect and fast replacement for my old model L.  It sounds like a car horn but it does the job. It would have made it easier for me if they would have put this in the description. I know this will help a lot of other people.
Will fit exactly where the old one did. Could be a little louder. Thought that the sound the horn made was a little on the weak side.
This horn was a great replacement for the original below-deck horn in my boat. The OEM horn had a stud on the top which a mounting bracket attached to get the 4" apart mounting holes. This model has a plastic piece that serves the same function. Mounted this piece below deck and used the original grill. Has easy spade connectors just like the original.
My thoughts anyway...Horn is loud and I expect worry free operation for many many years.
item arrived quickly. is well made and works fine. turned out to be the wrong size (my fault) so I carry it as a spare.
This drop in hidden horn was a perfect fir on my Chaparral 200 ssi sport boat. The horn sounds well and I am happy with my purchase.
Shipment was quick, it was easy to install, I already had a grill from the original faulty horn, this one works well,  I am happy with the product.
