understanding prop pitch?
Currently I have 15x23 3 blades on SSM 2. What would happen if I went with a set of 15x25 3 blades with everything else being the same. I found a really great deal on them and was thinking of gettng a spare pair of props.

Re: understanding prop pitch?
If the 23's were the perfect prop, ie low slip and the rpm's in the correct range, then you would go slower because the engine would now be below the correct rpm range. If things are less than perfect, ie there is too much slip, or the engine is above the desired rpm limit, then you should go faster with the 25's. If the engine is below the desired rpm then you will go slower because the engine will be bogging. Ultimatly, if the price is right, just make the sale contingent on you being able to try them. Naturally, you should pay shipping both ways. If you damage the prop in any way, then you own them, so be careful.

So if I'm running 23p at 4700 rpm WOT should I drop to 21 and try to get more RPM out of the engines (last post potentially 400 more RPM)? Thus potentially picking up a little more speed

Throttle Up
I'm running twin Gen V 454 mag efi's, 385hp
Actually just found a slight ding in the starboard side prop, I'm going to need a little assistance in getting it back true

Sorry to jump in your thread, thought my question was similar in nature.
