13.25x17 vs 14.x17 please help

[doggreen13]

Hey guys i got a quick couple questions, first my prop that my boat came with
was beat up pretty good so i bought a new one,but i just noticed the new prop is a 13.25x17 and the old one is 14x17 what am i better off with ? the boat is a 15ft rinker bow rider with a 115 erude 1985 boat 1969 motor, next my switch for my panther tilt burned out os what i did for a temp fix is just cut the red and black wire off of the where they went into the junction and just touched them directly to the battery red to red is up red to black is down, how can i wire a switch into that without buying a whole new gizmo ?

thanks

Theoretically you will get more RPM with the 13.25 x 17, if the geometry of the propellers is similar. For your tilt switch just buy a suitable sized toggle switch that will handle the amperage of the power needed to operate the tilt switch. Remember the longer the wire length the larger diameter the wire that is needed.

You need a toggle switch with 3 terminals hot to the middle terminal ,up to one down to the other.3 position switch off in the middle.I believe called a single pole double throw switch. Probably only operating the relays just be sure it can handle that amperage.
