I noticed a small leak from the weep hole on my lower unit when it was parked in the driveway.I pressure checked it and all was good .It held 15 lbs. for a week .I turned the prop to give it a chance to leak at different positions but it held. All last season I had a small loss of fluid and I am sure I have a leak. Someone suggested a leak at the carrier plate ,under the impeller but I cannot find any info on that .Can someone shed some light on this for me ? Thanks,Bob
