The NR .12 can be a pain in the butt to get broken in. Be patience You will NOT need any waterlines to the engine. The hotter the better. Keep CKing the head before you launch, you want it warm before you launch. Keep the retrieval boat handy ,we would go 1/8 lap then 1/4 lap and so on until she broke in. 3 hrs later. She likes to stick @ TDC on the piston/sleeve ,when starting. Ask Glenn about a finned airplane head button to replace the water-jacket head. And a small starting belt as the flywheel is small. A regular belt is too wide. Having the right belt is needed. .150 dia on the flex cable and cable coupled. Do not let the cable @ coupled spin ,Double CK making sure it's tight. If it spins free you may break a rod or worse.
Boom tubes ,yes get a few spares solid or open will work She will take a beating the hull is solid. I kept hitting buoy 6 at first. Keep your rudder trim way down ,they turn on a dime. Always have a drive line greased and a prop on before starting. Never pull the trigger all the way back ,setting on the table. Joe's props are very good out of the box. 438 -440 size. One Should always balance the prop and CK all before you get wet.
