Re: honda tilt and trim
With the engine tilted all the way up,the tilt locks in place,and you looking at the back of the boat ,that resivior cap will be the small somewhat bulbous cap looking thing towards the right and top of that whole tilt assembly.With several rags and a drip pan ,remove that cap SLOWLY, then fill with the correct fluid, good to go.Why are you in there in the first place?
