65 pontoon without aux oil tank

I have a 65 pontoon without the aux oil tank. Question can I fill the oil tank on the engine or do I have to stay below the fill line for the aux tank.

Due to that oil tank having a vent line it would be safest to fill it no more than 90%. I have a pontoon 90 with engine oil tank that has the fill line on it and have been filling it to 90% for a couple of years with no problems.
The worst that could happen would be that you might leak a bit of oil when the engine is tilted up.

You do not have to fill the tank up to the top. Many folks only fill to about 1-2" down from the upper edge of the oil tank.  Use a magic marker to make a fill mark for convenience.
