1. General (2) Selection of marine gear lube oil Use the following engine oil API classification ......... CD or better (Standards of America Petroleum Institute) SAE viscosity ......... #20 or #30 (Standard of Society of Automotive Engineering) (3) Selection of lube oil for sail drive unit API service grade ......... GL4, 5 SAE viscosity ......... #90 or 80W-90 or QuickSilver High Performance Gear Lube QuickSilver ® is registered trademark of Brunswick Corporation. (4) Handling of engine oil Carefully store and handle the oil so as to prevent dust or dirt entrance. When supplying the oil, pay attention and clean around the filler port.
Do not mix different types of oil as it may adversely affect the lubricating performance. When touching engine oil by hand, the skin of the hand may become rough. Be careful not to touch oil with your hands without protective gloves. If touch, wash your hands with soap and water thoroughly. 1.3.3 Cooling water Use clean soft water and be sure to add the Long Life Coolant Antifreeze (LLC) in order to prevent rust built up and freezing. If there is any doubt over the water quality, distilled water or pre-mixed coolant should be used. The coolants / antifreezes, which are good performance for example, are shown below. TEXACO LONG LIFE COOLANT ANTIFREEZE, both standard and pre-mixed.
Product codes 7997 and 7998 HAVOLINE EXTENDED LIFE ANTIFREEZE / COOLANT Product code 7994 IMPORTANT: Be sure to add Long Life Coolant Antifreeze (LLC) to soft water. In cold season, the LLC is especially important. Without LLC, cooling performance will decrease due to scale and rust in the cooling water line. Without LLC, cooling water will freeze and expand to break the cooling line. Be sure to use the mixing ratios specified by the LLC manufacturer for your temperature range. Do not mix different types (brand) of LLC, chemical reactions may make the LLC useless and engine trouble could result. Replace the cooling water every once a year.
When handling Long Life Coolant Antifreeze, wear protective rubber gloves not to touch it. If LLC gets eyes or skin, wash with clean water at once. 5
