Situación de la aplicación
Erosion and corrosion caused a major loss of metal in the jet drive transom housing.
Método de aplicación
The transom housing was blasted to a near white metal finish. A former was manufactured to mold the critical clearances to 1-2 mm between the removable jet drive and the boat transom housing. Once the rebuilding and molding was completed, two coats of Belzona 1321 were applied.
Datos de Belzona
