1. Check the oil level with the engine warm, idling, and the clutch engaged. 2. Maintain oil level at the FULL mark on the oil level gauge. Add oil through the breather tube on top of the marine transmission housing. Refer to Lubrication and Maintenance Chart for proper oil to use. Draining Lubricating Oil
1. Remove the marine transmission drain plug. If a sump pump is used:a. Connect a drain line to the top outlet of the sump pump. b. Be sure the valve on the engine oil pan line is closed. Marks on the valve must be turned at right angles to the direction of the oil line.c. Open the valve on the marine transmission oil line.d. Operate the sump pump handle until the oil is drained.2. Remove the marine transmission oil filter housing drain plug. Installing Marine Transmission Oil Filter Element
1. Drain the marine transmission lubrication oil.2. Remove the cover assembly - with filter attached.
TYPICAL FOR ALL 7200 TRANSMISSIONS3. Remove the nut, retainer, and element from the cover.4. Clean the filter housing and the cover assembly with clean solvent.5. Inspect the retainer plate seal, and cover seals. Install new seals if necessary.6. Install a new filter element, the retainer, and nut to the cover assembly. Tighten the nut to 10 2 foot pounds (1.38 mkg) 7. Install element and cover. Tighten all bolts.8. Install the drain plug.Clean Marine Transmission Oil Strainer
