I have a pontoon boat with this motor, seems to run fine, has about 200hrs on it, new to me.
After pulling the kids on a tube for a while and getting up to 5500 rpm we slowed down and stopped and swam for a while. When I started the motor to leave I noticed some oil on the water, not much but it was still a little concerning. Before we stopped I think I saw a little bit of smoke that I hadnt noticed before either low to the water.
Engine was serviced by a dealer and i've only run maybe a tank of gas thru this since buying it so far. I took it easy on the way back to the dock and checked the oil once the boat was out of the water (seems to take an hour or 2 for all the oil to drain back down to get an accurate reading) and it was full, didnt notice anything wrong really, the rubber grommet for all the cables going into the motor was broken so maybe some water just got in there due to the higher speeds and drained out while we were sitting and caused the oil slick, that's what i'm hoping anyways. I'm new to outboard motors, seem like anything to be concerned about?
Can anyone recommend a good oil for this motor and lower unit? Don't really want to pay the premium for the mercury oil if not needed. Manual calls for 25-40, I'm in Texas so its quite hot out in the summer.
I was going to change the spark plugs (no idea if its ever been done) and just change the oil and lower unit oil for good measure while I was at it.
Thanks in advance!
