the first question is.( its a 76 mercury 650 thunderbolt, 65 hp, 4 cyl. on a 13 foot cane cutter, has any one heard of that model boat)<br />1.I very recently had all the seals re-done on my lower unit, had water in it and all that. so i gather from all the other post's that milky or creamy gear oil means water in it. well mine looks yellow. was pressure tested held 17lbs of pressure for 2 hours. any more water leaking seals i should know about.?<br />(and number 2)<br />2. when me and someone else get in the boat and give it full throttle it will not go over 5 miles ph.<br />but when they sit in the middle it slowly planes out and goes 58 mph. same with just me in it.<br /><br />any help soon will be good.
