All the rods seals in this kit are made out of Viton a very expensive super material formulated by Dupont and will resist everything from ethanal to UV's to Oxidation from salt water environments. You won't find a better kit anywhere for this application, once properly rebuilt these seals will outlive the life of the motor. We also included the 5 O-rings in between the valve body and manifold, if your unit is giving you issues the valve body needs to come off and the 5 O rings need to be replaced. This was a flawed design put together by showa, in a Freshwater application on a bass boat you will see the bolts have stretched and losses their torque form the hydraulic pressure in between the valve body and manifold. In a salt water application salt and corrosion builds between the flange and wedges it apart as well as oxidizing the O-ring grooves and forcing them to fail and fall out of place. 

 

If for some reason you cannot build the unit, we offer a rebuild service and we will credit you the amount for the rebuild kit towards the rebuild service. All of our rebuild services come with a 2 Year Warranty.
