Since most outboard engines use a 50:1 ratio, it can be daunting to convert and figure out. The easiest way is to stop at Walmart, go to the sporting goods section, look by the boat items, and buy the plastic oil bottle that has the pre-marked lines that will show how much to add to how many gallons of gas.
No. There is a oil tank much like your car that you top off.

From the oil you mix in with the gas
yesw 16 to 1
it's 50:1
mix 50:1
50:1
The gas/oil mix for a Force 50hp outboard is 1:50
Without knowing the year, I can only tell you what is a safe mix. Fuel/Oil mix: 24:1 (87 octane gas to TC-W3 rated outboard oil), would be a safe mix. If you find that at this mix it smokes excessivly, then switch to a 32:1 mix, which is still a very safe mix.
50 to 1 according to my mechanic
