need help on correct prop b-2 b-3 b-???

[pine island fred]

am helping a friend with his boat chaparrel 2370 87 year. he has a 501 duoprop ( chevy 305 ). have determined all prop are 16 in. diameter, and use the series B. but there are b-2s 3s 4s 5s (alumnium ) not much left of the present props but one is a b-5 which looks pretty agressive in pitch and the other is a no nbr sort of put on to fill the space. engine would never go over 3200 rpm and am thinking the b-5 was oversized. anybody have any ideas ? almost forgot, its a volvo/penta. thanks fred.
