How do you drain your bravo 1 .. and replace with new oil 1990 b1 just won't to make sure !!

pull the prop , take out the screw on the back of the housing , i take the lid off my bottle inside the boat . let it drain compleatly . go buy one of those cheap do it yourself fill kits . get yourself a garden spayer and conect the filler fiting to the hose , fill the garden sprayer with what ever oil of choice , mecury hp is great , pump up the sprayer with air open up a refreshment of choice , i prefur a cold bud light and pull the trigger and watch the syrup flow baby . simple as that it takes about 3 qts , i use royal purple 75 /90 synthetic gear lube from napa . watch youre bottle inside the boat fill it till youre at youre fill level , youre done , put the screw bak in making sure you dont loose the gasket or o ring , thats it , 20 minute job tops easy stuff man !!

Thanks Rob .. time to get on
