I just bought a 14ft Alumacraft Deep V boat and the 1981 Mercury 25hp needs a new prop. I'm not sure how the boat handles now with the one that's on it now. I think I would like to at least pull a tube at some point with it. I'm wondering if I should just get the stock 3blade 10x13. Or Jump to a 4 blade? Any Suggestions?

No big deal but I doubt your little 14 is a true deep V.
I would suggest you do a base line test with a tach and a gps.
You can get a tiny tach about $40 and very easy install.
With a good base line we can get an idea of your setup and make some suggestions.I would check out the Turning Point rascal in the 13" pitch.
If your presently running a 13 you could get one but you really need to know your rpm and speed to evaluate your setup for best performance and motor health.

Since you have no idea how the boat performs now you should not even be thinking about prop changes.

Thanks for the advice. I checked the prop tonight and it is a 13" pitch prop so I think I will buy a direct replacement for that since it is also the stock prop that comes on that motor and I will think about getting a Tach.

Steelspike - Actually, for a 14ft boat, its huge. It is almost 70" wide and is rated for 5 people/1150 lbs (motor, gear, people). I was surprised it was only rated up to a 25hp motor. I attached a couple of pictures so you can see.

Trim tab is missing .....that will be a Bear to steer without one...
Yes, that prop is shot too. A 13P may have come with the engine but that doesn't mean it's right for "that" boat and "your" load.

Thanks Walleyehed. I noticed something didn't look right and couldn't put my finger on it. I have to get a few more things for the motor and will be sure to get that as well.
