Merc 125 prop?

[pokman]

Hi guys I got a aluminum 21p on my 94 merc 125 outboard. I am thinking about changing to a ss-same pitch. I have seen a few on craigslist for 175. Will I gain noticaeble performance. Basically I would like better hole shot and a few mph top end would be great. I get 48mph speedo now running at 5200rpm which is right in the range for the motor. So if anyone has a 125 and could recommend a prop that would be great. Boat is a 17ft rinker captiva

Re: Merc 125 prop?

What is your WOT range?
Have you dialed in your motor height yet?
do youhave access to a GPS for accurate speed numbers?

WOT range is 5000-5250. Like I said I run right at 5200. Motor height I am not sure just bought boat and po said this is how the motor was setup when he got it years ago. I haven't used a GPS yet, I had it to 48 on speedo, po had it to 51 on speedo so I figure it is running around 45 on GPS.
