need Prop identification help

[davis]

Hello, i need some help with what pitch prop to buy for my outboard , the number on the prop says 4873138A40 14P, if I was to put a higher pitch on what difference would it make, as there would sometimes be a few people on the boat, thanks

Mercury ali 3 blade 14" pitch.

You need to know what revs you are doing at the moment at full throttle. If you are almost hitting the rev limiter then you can go up a pitch or 2 - if not then there is no point.

Also what speed are you getting?

If you increased the pitch by 1", your top end rpm would be reduced by around 2-300rpm.
