hey guys! new member and new boat owner here so bear with me!
while I'm waiting for my parts for the recoil to come in I decided to change the plugs and the gear oil in my mercury model 200 20h.p. today.
I knew I had a small leak of oil coming from the prop all winter. Just thought it was a small leak. Finally got the boat going and didn't bother checking it until today (I only ran the boat for maybe and hour this year, until the pull string and recoil broke in the middle of the lake). I knew I had to check the oil but it was just one of those things I kept putting off.
I began by removing the bottom screw and found nothing but water coming out NOT GOOD. Removed the top to vent it and got a TINY bit of oil to run down into the pan. guess that's what I get for not checking it!
I put the bottom screw back in and began putting new oil in (which I did from the top screw because it threaded onto the oil tube) I pumped 8 ounces in (calls for 8.2) and watched all of it either pour out of the prop or out of the vents (not sure exactly what they are since this is my first motor) I assume these vents are for letting water in to cool the oil which is cooling the gearing. these vents are just forward of the prop and there's 6 of them on each side of the lower unit.
my best guess is that I should have put the oil in the bottom screw and seen if the oil would have came out of the far left (smaller screw)
Of corse I figure I need a new seal in the lower unit housing that's a given. But I cannot figure out why the oil is coming out of those ports. doesn't make any sense.
