Changed the oil on my mud motor build. Built with a backwater 6.5 ultralight long shaft boat motor kit, I installed a harbor freight predator 212 6.5hp engine. I ran it for about an hour with some supertech 10w-30 synthetic I had laying around, it had lots of glitter in it which is totally normal for break in oil out of these engines. Replaced it with some rotella 10w-40 oil and will run that another 3 hours then change again to its normal oil with will be cabelas 10w-30 boat oil this season then a 10w-30 synthetic afterwards. It will only see 20 hours max on it since my duck hunting spots are pretty close to the ditch I put in at. My big concern is the fact it’s tilted much more than if it were on a rototiller so I put a little more oil in it to compensate, hopefully the oil splashers can do their thing.
