Corect ! O elicie la scara trebuie sa aiba 23.7 mm diametru. 25 mm e o aproximare buna.
Arborii trebuie sa fie Water Proof caci nu vrei sa-ti intre apa in nava. Arborii navo au de obicei la capatul dinspre elicie o "presetupa" (etansare pe ax) care impiedica apa sa patrunda pe langa ax.
Cu stima!

Si inca o chestie ca sa ma lamuresc:

Acum eu ce sa inteleg ca primul este in totalitate waterproof iar cel de al doilea are doar la capatul de la elice o etansare pe ax?
