We explore the connection between the stiffness of an hadronic equation ofstate (EoS) with a sharp phase transition to quark matter to its tidaldeformability. For this we employ a hadronic relativistic mean field model witha parameterized effective nucleon mass to vary the stiffness in conjunctionwith a constant speed of sound EoS for quark matter. We compute multiplescenarios with phase transitions according to the four possible cases of ahybrid star EoS with a stable second branch. We demonstrate at the example ofGW170817 how the effective nucleon mass can be constrained by usinggravitational wave data. We find, that certain values of the effective nucleonmass are incompatible with GW170817 and a phase transition simultaneously. Byusing the recent NICER measurements of J0030+0451 at the $1\sigma$ level weconstrain our results further and find that strong phase transitions with avisible jump in the mass-radius relation are ruled out at densities below 1.7times saturation density.
