First off let me say thanks for all the help I have received on this site you guys have really been a great help. Now I am experiencing a new problem. I had my boat out on the water today (finally) and things were going okay, in the beginning the motor would not get up to full throttle but after about an hour the motor just kicked in started working like a champ. I ran it around the lake did not seem to have any problems and then all of the sudden my engine revved up but i was no longer moving forward. I shut the engine down pulled up the motor to check the prop. nothing appeared to be out of order so I started the boat up put it in forward and slowly increased the throttle. The boat will move kinda sluggish but still forward motion until I reach about 5mph then the engine just revs up again so basically I limped it back to the ramp. The engine stayed cool and the still seems to be running fine. I unscewed the lowest oil drain screw and milky oil came out. This does indicate a leak but I had the lower unit pressure tested and it checked out fine. Is there anything specifically that I should be looking at which would cause my problems? Thanks for any help I can get
