Hi i have a 1999 chris craft 240 express cruiser. I want to do a gear lube but have been told i need a special tool "puller" to get the 2nd prop off. I have to take the props off in order to get to the drain plug. Can someone let me know what exactly this tool is called and perhaps a link of where i can purchase one. Thanks. The engine is a Volvo Penta 5.7 I/O
