Ya thats what they say on the web site 1.5 and 1.75...you can tell that I had the boat look bad so I fix that ...yes its leveldam interesting spring height...rear is lower than the front
are you on level ground?
sounds like a bad shock to me
Springs determine ride height, shocks determine how the spring is controlled (oscillations).
Double check that the top of the springs are fully seated in the top mounts; the rubber is not worn down more on one side than the other (rubber in the top mount).
Double check that the spring is rotated correctly to fit in the bottom perch on the shock. The end of the spring should sit all the way into the "Z"-shape of the perch, and then backed out a little so it doesn't rattle.
