[QUOTE="jasper60103, post: 225759, member: 1810"] Congrats on the new rig. Yea, changing the lower unit oil is pretty easy. Your friend was wrong on the amount of oil needed though. But it is cheaper to buy it by the quart rather than those 10 oz tubes. Just fill until it overflows the top hole. Regarding your fouling of spark plugs, start with the basics. Here's a few things to check... 1) Make sure your fuel mix is 50:1. More than that could cause your plugs to foul. 2) Check the spark plugs, and make sure they're the correct plugs and gaped according to the spec. 3) The carb slow speed needle could be adjusted too rich and cause plugs to foul.
