New to Bowrider 210 last Fall and this is my first de Winterizing season. As it relates to the 5 blue wing nut water plugs on the engine and manifold: They screwed back in the plug holes easy enough. Lacking a little confidence I put them in the right places! They are sometimes tough to find! Are there any "fake" drain plug holes I could have put them in or is there just the right number of drain plugs for drain holes that fit only them? Photos would be of help! Any assistance appreciated!
