What is the diameter nested for the hole to mout these in a boat? Is it he cut out 5" in diameter?

yes, but you may need a little more room than that depending on the angle you insert them at, they are deep

Go to Polk audio .Com and look up this speaker. On the specs it will tell how big the hole needs to be.

My boat is still in winter storage, but I think it is 3 1/2 inches (or very close). Won't be able to measure it for a few weeks.

Inside diameter of the nock hole is 0.190". The vanes are pvc, but break fairly easy. The shaft is aluminum and the tip steel. I've had many vanes snap off from just hitting a box filled with towels.

The length is about 54 in, and the inner diameter of the hole is about 1 in. The diameter is actually a little less than 3.25 in. It's more like 3.1 in. It's hard to say because they don't stay perfectly round.

It is cut square. I haven't had an issue with it though, as it is a little larger than my boat. I have been able to tuck it inside the motor and still keep it dry.

Yeah, I used them in a speaker tube for a 4 wheeler. I used 6" pvc and had to make filler rings to catch the mounting screws. So that hole pattern is closer to 5.5 ". I didn't really measure it.

View shown is approx 8 inches, the neck part that goes thru the hatch or opening thru the deck is less than 5 inches (maybe 4.25 ", it is on my boat and I won't be able to measure it until tomorrow evening, I bought the "Hole Saw" from Lowes (cost for pilot and saw, was 35 dollars)... The features on this model are better than some units at twice to three times the cost, fan is reversible and the night light is a "Led Blue" circle around the base....

About 5 inches between holes but the holes are small. Not sure how to answer your diameter question.

The inside diameter is roughly 2 inches. The screw holes are .25 inch. They are lined inside with black plastic and have the X in the bottom for keeping the rods from twisting. I just installed 2 for trolling in the rear of my carolina skiff.

I am not sure but it may be a 1/2" outside diameter. It was too big to fit in the hole on the engine cover and I had to buy a different brand at my local boat shop for around $52. Hope this helps.

I cannot tell you the diameter but there is a seal for it. Perhaps the Amazon people know the diameter of the hole itself. Good Luck!

Generally used on boats. I had to drill an 1 1/2" hole to mount it. My guess would be ... no, it's too big for a direct replacement.

Approx 4 to 5 inch diameter, but with the shape and hope it is made, it is very difficult to return back throuogh it. These worked great for crab fishing off a dock!!!

My boat is still covered in winter storage so not accesible. The diameter would be close to 4 inches and the bracket depth would be close to a half inch on the outer edge of the horn. The depth center middle to back would be closer to 2 inches best guess.

The speaker grilles are 5.25" in dia. They worked great in the bow side cushions on my boat.Dean

I don't know. I wouldn't go less that 5 inches in length. Just because I don't want to get my fingers that close to the cutting head. JP

The hole is 4 1/2" X 6 inches. It's shaped like a rectangle with rounded corners which makes it somewhat oval shaped.
