Today is the first time ive tried to swap props, ive got the hub out of the old prop and when i drop it into the new one it sticks out about 3/4 of an inch. Am i safe to seat it with a soft mallet or will it seat when i tighten the prop nut? i dont really want to break something on thanksgiving weekend when no one is open. Old prop is a 24p tempest and new one is a 25p new out of the box, on a 16 merc proxs 2 stroke 200hp.
