Ok so I’ll admit I am new to boat engines. Mechanically inclined but new to boats. We recently purchased a 2012 pontoon with a Suzuki DF60A motor on it. When I purchased I checked the oil after running while connected to the hose for 5 mins. I think my downfall was I didn’t have it in gear for more then the time it took me to check and
and sure the throttle linkage was good. When I pulled the plug and checked the lower unit oil it was clean as could be. Not milky it looked brand new. The motor apparently has less then 25hrs on it. We took it out this week and ran it for a good 8 hours. Trolled a lot while fishing and a good couple hours ripping up the lake 3/4-full throttle. When we pulled it out I noticed milky oil from
the water intake port. I then checked the lower unit and it’s milky. No metal filings in it. Drained it tonight and no metal filings on the bolt or in the oil. Just looks like milky oil doesn’t smelt burnt either just like gear oil. Apparently the guy bought it for his kids but they bought a wakeboat so never ended up using it. It sat for the last 2.5 years and was ran for 15 mins a year. Basically from the boat launch to his lift where it sat. Not sure if this dried the seals out. He had also mentioned something in the prop assembly was replaced because they left it tilted up slightly in the winter and it got water in it and froze. He showed me the piece they replaced and to be honest it looked like the mechanic was trying to remove the bearing housing and used a puller on it and broke 2 pieces off. It’s not cracked but rather broke in the same spot on either side like it was pried on. Doesn’t look frozen so not sure if this is maybe a seal issue down there however with it coming out of my intake ports I would assume it would be an upper seal? I also didn’t replace the washers on the oil plug when I checked it when we bought it. Tonight after reading up and realizing these should be replaced every time there taken off I noticed there actually quite hard. More like plastic then rubber so hoping this is the easy fix. My plan was to drain the oil over night then “flush it” with cheap gear oil. Fill run for 5 mins, drain hot, fill and run again till my oil runs clear. Replace cheap oil with marine oil and replace plug gaskets. Take it out on the lake again then check oil again for water. Any other advice on my plan or opinions on what his maybe? Common issues I’ve missed?
