 2023 OWNER’S MANUAL 
This situation is worsened if the boat is stored without proper 
ventilation or if the boat cover is put on while the vinyl is still wet, 
creating a situation in which all forms of fungi (mold and mildew) 
thrive. Failure to follow these instructions in the proper care of 
upholstery may cause your warranty to be voided!
The cleaning table presented in this section is oered only as a 
suggestion and as an aid in attempting to deal with stains. We do 
not guarantee that the cleaning methods will work. Stains from 
any external source are unlikely to be covered by warranty.
