Can anyone tell me what the numbers on the prop mean? The last number is the pitch I know but the others I don't know. 48 77350 A45 23P is on the side of the prop and 48 77350 C1(or Cl) 23 is on the back of the prop on the hub. I have found a prop with the numbers 77348 A45 which is a 21" pitch. Can I determine from these numbers if it will work on my boat?

No, It is not overreving. More like a bog. You let off so it will drop and then have to trim to compensate. If you compensate too much when it gets on down then you have to be quick not to overrev the motor by lowering it a bit more.

The prop on it is a 23 pitch. The latter of what you stated seems to be a possibility as I can let off and get the boat to come down some and then hit the throttle and trim it and move on. I guess I need to know what came stock on this motor/boat combination. This is a Bass Pro Shop combination that I bought used. I really don't need anything bigger at this point. The top speed i have gotten it is 53 and I don't need to go that fast. I just want to get it up on the water without having to monkey with it. I have really paid no attention to my rpm's since I knew literally nothing until today about all this pitch and everything. I've been trying to find my motor manual for info. I'm from the old school where you sit in the front of a flat bottom boat and crook a paddle in your left arm/shoulder and fish with your right as you go around the bank. I'm ready to move UP though! THANKS for any and all info.

Yes, I am trimming all the way down when I start out. It starts to come out of the water but won't finish and sit down. It just seems to hang there and to get it down and going you have to start trimming. That's the reason I think I need to go down in pitch.

I'm not trying to measure the pitch of the prop, just the diameter so as to know what size prop I have. Isn't that what size is, the distance across the blades, tip to tip? I am trying to find something similar to mine on ebay just so I will have an idea what I'm looking for.

How do you measure a three blade prop? Can I just measure radius and double? I was thinking a 21" would be what I need to try. Thanks for the info. so far.

My prop is a 23" pitch. It is on a 90 hp Mercury behind a Nitro LX 700. Slow out of the hole. Anyone know what stock is?

I would appreciate anyone that has experience with changing props to match a boat with using conditions to shed some light on me or tell me where I can read up on this. I have to replace a stock prop and want to make an improvement. If anyone can help it would be appreciated. Great site.

Sorry for the post in the wrong place. If someone can move it to the correct forum do so and I will check it out after work. Thanks

This is my first real bass boat and have some things to learn. This weekend I managed to ruin the prop by getting into the mud flats. I haven't been impressed with the Nitros ability to get up and out of the water. After happening on your site by using a "Nitro" search it led me here and specifically to a forum question on the Nitro. I see now that it is underpowered. It will still work for me for a while but since I have to replace the prop I am wondering what I need to get that would help it out. I was told that the prop is more of a speed prop and that I need to go to something else. Remember that I know very little at this point so any help will be appreciated. This is the 90 horse Mercury motor and a 1999 year model. I have numbers off the prop if needed. Thanks
