I have a 14 lowe line with a 20 Go Devil LT. It is not performing as i had hoped. It will push over and through things but has NO speed in the open water and canals. Will sponsons help ???

Probably not...

Is it not plaining?
What are your RPM's?
Is your prop worn?
What kinda load did you have?

Sounds like you are putting too much weight into too small of a boat.

Replace the prop, but you probably still aren't going to plane that load in that little ass boat.

Damn, I was hoping the performance pods would help.

You won't plane that load.

When the planets align I have gotten 3 little guys and 4 dozen deeks on step and running about 14-15 with my 24.
moving a decoy bag made the difference in plaining out.

I need a new hull, I am going to get at least one more season out of this one before I turn it into a pond boat. I just wanted someone elses opinion other than MB on their performance pods. They are only $299. I need a new dog ladder anyways , thought i would kill two birds with one stone.

I run a 1542 with a 20hp GDLT - get decent speeds - just got a new prop - so that helps
As far as getting on a plane... I think a bigger boat is what you're looking at. Mine is no speed demon - but it gets me in and out of where I feel comfortable taking it.

Let me know when you try a 9hp GDLT with 2 guys and 4 doz dekes and a blind and hunting gear on the 1542 - prop worn to 7-1/4" x 4
lol
7mph is about as fast as we can go
BUT - still goes where I need it to - just slower

Yeah I know - need a new prop
Need more money too...
