aintenance
Note:
Painting the propellers requires special care at attaining a smooth surface. A
rough surface on the propellers will seriously affect the yacht's performance.
Caulking and Sealants
Stainless Steel rails and hardware
Never use abrasives like sandpaper or steel wool to clean stainless steel fittings or
rails. Never use mineral acids or bleach to clean stainless steel. Never let stainless
steel come into prolonged contact with iron, steel or other metals which cause
contamination leading to rust or corrosion.

If you need additional information on priming and painting the underwater
metal components, please contact your Marquis Dealer's Service
Department.
Deck fittings, rail bases, window and all underwater fittings have been
sealed with the finest quality sealants. These sealants, however, do not
last indefinitely. The working action of the yacht and the expansion and
contraction caused by variations in outside temperature eventually break
down the sealant.
Fittings that have begun to leak must be resealed. Remove the fitting and
clean the old sealant from both mating surfaces. Reseal the fitting using
the sealant recommended by your Marquis Dealer.
Stainless steel is not rust-resistant nor is it stain-resistant. When left in
contact with the marine environment it does rust and corrode. Proper care
helps keep the stainless fittings on your yacht looking bright and shiny.
Clean the stainless steel rails and fittings after each outing with either soap
and water or glass cleaner. If you operate your yacht in salt water, clean
the rails and fittings at least once every week, even if the yacht hasn't
been used since the last cleaning. If rust appears on the metal use 3M
Metal Restorer (Marquis part number 051131).
If you discover any rust, remove it immediately. Failure to do so leads to
irreversible pitting. Use brass, silver or chrome polish to remove rust on
stainless steel. Wax the stainless fittings and rails to help protect them
from the elements and keep them looking their best. Use the same wax
you use on the fiberglass surfaces of the yacht.
The hatch frames on your yacht are fabricated from aluminum or Stainless
Steel. Some of these frames are painted with enamel. To clean both the
painted and unpainted frames, use a sponge dipped in a solution of fresh
water and mild soap. Do not use a brush or abrasive cleaner as these can
scratch the painted frame surfaces, damaging their appearance.
The cabin windows are made from tempered glass. Clean them with a
soft cloth and glass cleaner. The bridge wind screen is made from formed
plexiglass. Clean it with a solution of fresh water and mild soap.
