I went to the lake yesterday for the first time this year. I bumped the rudder on a rock leaving the loading ramp, not very hard though. I noticed once we got to the dock that the boat had about 2" of water under the motor. I bilged it out and about every 2-3hrs I would check and have about the same amount. The motor is not leaking anywhere and I cannot see water dripping out of anything. does the rudder have a seal that may have broke loose. At the end of last year it did not leak. The boat was also parked with the waves hitting the back of the boat if that makes any difference.
