Just learned something about my propeller. It is three bladed warp drive 60 in. I made a phone call to manufacture and they tell me that this size of propeller typically too small for 100 hp engine.
That is an explanation for my 18° pitch.
But I don't have any complains about its performance. Can I keep it and fly this way??
I fully agree that a 60" Warp is too small. You are definitely losing performance. If you increased that to 66"-68" you would see a big improvement.
At one time I had a 66" Warp on my plane. Then I did a large research project for a couple companies with 14 different props. The Warp was equal in cruise performance, but suffered from all others in climb and if you add in a 6" difference it would be a major difference.
Personally I would consider going up to a Warp 66"-68" with NO nickel edges. If you want more leading edge protect use the tape.
If you really want to make a change then move away from the Warp to something like a Sensenich or one of the other Mfg's.

What kind of performance I am losing? Takeoff performance?
Flying straight and level?
I am very happy with everything, but I have next to nothing as far as experience goes.
I cannot get bigger propeller, because I have pusher airplane and propeller blades Will cut my own tail off.
I guess my only option is to go for 4 blades.
Warp drive guy on the phone mention that about 20° pitch on the propeller needed to go 170 miles an hour.
Can I just keep it this way. Is it bad? After all my WOT @ 4000ft is 5560 rpm and I am not looking for short field performance at all.
To me, looks like I have cruise propeller, that's all.
It would have better performance, but evidently you have a physical limitation and it's working so if you can't change it don't fret and leave it alone. Your WOT rpm is just fine.
4 blades won't help you.
Is the Warp the factory prop? Is the an ELSA or SLSA? How much distance between the tail boom and prop tip now?
