Caution for installing FRP tank
Use an FRP tank supplied by FURUNO. Other makes of tank may be used, however
watertightness cannot be guaranteed. A non-FURUNO make of tank should meet the
following requirements:
- The surface of the FRP tank flange must be flush (within 0.5 mm) with tank.
- Use the sealant recommended by shipyard.
