New prop - periodic engine vibrations

we've got a new prop (3-blade, fixed) and we have observed that the engine trembles slightly cca every 5 seconds. The vibration is very light and it's constant across all rpms. What might be the reason? Too small pitch? This propeller should be a copy of our old one, but probably not a 100%.
Many thanks for any insights!
