2000 Mercury 25HP Prop

Has anyone ever replaced their prop on this motor or one similar? My prop is torn up some and I was thinking of replacing it and seeing if I can get a different pitch to help with my speeds. Any help is appreciated!

2 stroke or 4? I have a 94 should be pretty similar to yours if its a 2 stroke. The hub is biilt into prop I run a solas amita aluminum 3 blade 13pitch. It pushes my 1648 with 2 people and gear at 28mph I could probably get away eith a 14pitch as the 13 is at upper range of recomended rpm but when I throw in more gear or people the 13pitch comes in handy.

Yes it's a 2 stroke so it should be similar. Right now I'm getting about 26MPH with two guys with the bad prop.

I have this prop on my 2000 Merc 25hp

What is current prop? Do you know your max rpms? What boat?

I do not know the rpms. It is on a 1648 flat bottom Jon. And the only info I have on the prop at this time is the pic below. Looks like it's a 12 pitch?

Its hard to say without knowing the rpms but heres my setup. Alumacraft mv 1648 (320 lbs) tolling motor and 2 batteries (135 lbs) 2 people and other gear (600) lbs. So im pushing an estimated 1055 lbs with an aluminum 13pitch and I get 28mph and am at the upper rpm range for the motor. Mercury says to use a 14pitch for the weight im pushing but I occasionally load heavier so I stay with the 13. Hope this helps.

I might get a tachometer before I get I prop so I have what I need to push the boat good.

My MV1648 was similar when I bought it. Never should have sold that motor.
Starting where you are, I would try the standard factory supplied propeller, 13P aluminum. Buy it from the dealer. Mercury makes good props. If this proves to be a little too small that's okay. If you're RPM's are a little too high you can step up to a 14P stainless steel. Keep the standard prop as a spare or, for when you are heavily loaded.
