High altitude gear ratio 1.87:1 is not available for SEI 216 units. SEI 216 is standard rotation. SEI 218 is counter rotation. When replacing a gearcase which has eight driveshaft splines, a two piece driveshaft must be used. The SEI unit will not come with the upper driveshaft or coupler. The OEM part numbers for eight spline upper driveshaft kits are: 45-824114A 1 ——– 20” model 45-823901A 1——— 25” model 45-824115A 1——— 30” model All SEI 216/218 gearcase models have dual-water pickups. SEI units come with a water tube coupling which is compatible with engine serial numbers 0G438000 and up. When replacing an OEM unit with serial 0G437999 and lower, the original water tube coupling must be reused, or a new one must be purchased. The OEM part number is 816597A1. The SEI part number is 96-116-12K. All SEI gearcases are shipped without gear lube. SEI 216/218 series gearcases are not designed to replace Sport Master, Torque Master, or other high performance gearcases. Call SEI for application assistance if needed. Have the engine serial number ready. Anodes and trim tab are not included. If you are not sure whether you are replacing a unit on a 2.0,2.4 or 2.5 liter V6 (SEI 206) or a 3.0 liter V6 (SEI 216), the easiest way to tell the difference is by the material that the water pump is made out of. See the picture below for help in determining what type of Mercury V6 gearcase you are replacing. Counter Rotation Identification If you have a twin engine boat, you may have a counter rotation unit on the port side. The easiest way is to confirm that is to look at the prop. If the direction of the blades are the same on both props then they are both standard rotation. If the direction of the blades are different then you have a counter rotation on the port side. If you currently have two standard rotation drives you can upgrade the port side to be counter rotating. There are a couple of modifications you will need to make. The first change will be changing the throw of the port shifter at the helm. You will need to remove the remote control to do this. If you are uncomfortable doing this, then seek the help of a qualified mechanic. The other change you will need to make is getting a prop that is the opposite rotation. If you are lucky you can buy the exact same prop, only LH rotation. If they do not make it, you will need to buy two new props, one LH and one RH. You don’t want to put two different style props on the boat.
