speedster 150 coolant change.

My boat is a few years old now and thinking of changing out the coolant... Does ANYONE know where to drain the coolant on the speedster 150. How much coolant is required???

Pop the plug out that is circled in red, open the cap on the overflow tank, let it drain. Ask a friend to pour new coolant in while you wait at the back for a steady stream of new coolant coming out of the hole with no air bubbles, then quickly put the plug back in and fill up the rest of the way.

Thnx soooo much for the help... Did it today in 15 mins... Saved $120 not taking it to the shop...
Used the new Prestone 5 year anti-freeze Poly-Glycol. Took just about a gallon... Mixed it 50/50 with distilled water. Probably have to top off the overflow tank when the air comes out when I run it..
