Operation 41 Bow Down Too much trim-in causes the boat to “plow” through the water, decreasing fuel economy and making it hard to increase speed. Oper- ating with excessive trim-in at higher speeds also makes the boat unstable. Resistance at the bow is greatly increased, heightening the danger of “bow steering” and making opera- tion difficult and dangerous. NOTE: Depending on the type of boat, the outboard motor trim angle may have little effect on the trim of the boat when operating. EMU27933...
