Operation51Bow UpToo much trim-out puts the bow of the boattoo high in the water. Performance and econ-omy are decreased because the hull of theboat is pushing the water and there is more airdrag. Excessive trim-out can also cause thepropeller to ventilate, which reduces perfor-mance further, and the boat may “porpoise”(hop in the water), which could throw the op-erator and passengers overboard.Bow DownToo much trim-in causes the boat to “plow”through the water, decreasing fuel economyand making it hard to increase speed. Operat-ing with excessive trim-in at higher speedsalso makes the boat unstable. Resistance atthe bow is greatly increased, heightening thedanger of “bow steering” and making opera-tion difficult and dangerous.TIP:Depending on the type of boat, the outboardmotor trim angle may have little effect on thetrim of the boat when operating.EMU27946Tilting up and downIf the engine will be stopped for some time orif the boat is moored in shallows, the outboardmotor should be tilted up to protect the propel-ler and lower case from damage by collisionwith obstructions, and also to reduce salt cor-rosion.WARNINGEWM01543Make sure that all people are clear of theoutboard motor when tilting the outboardmotor up and down. Body parts can becrushed between the outboard motor andthe clamp bracket when the outboard mo-tor is trimmed or tilted.NOTICEECM00991 Before tilting the outboard motor, followthe procedure under “Stopping engine”in this chapter. Never tilt the outboardmotor while the engine is running. Se-vere damage from overheating can re-sult. To prevent the cooling water passagesfrom becoming frozen when the ambienttemperature is 5°C or below, tilt the out-board motor up after it has beenstopped 30 seconds or more.EMU42681Procedure for tilting up (power trimand tilt models)1. Place the remote control lever in neutral.
