What size prop do you recomend for a short shaft 13hp build? It will be on a 1436 jon. Also what size gear reduction would be best? Thanks |

I got a 13 HP short tail. Honda gx 390 and turning a 9x9 but i think i am over proped. It's a dixie Mud motor on 1442 Alumacraft. Boat runs 20 mph all day long one person (24 WOT). Added my 300# pal and it ran 15 max. Felt over proped. Im going to change out to a 9x6. Looking for a balance of speed vs load Best of luck ! |

The 9X9 is probably the best bet with a 1.5:1 or 1.3:1 reduction. Going to a 9X6 is going to kill your performance, as it is not a surface-piercing prop, it is a sub-surface prop. |
