Marine Nitro Engine Break-in
 

guys how do you break in a nitro engine. i have a os vz-m, thanks in advance

Running in a marine-engine is different from carengines. Make sure it is somewhat riches then normal and in run your boat in the water. NOT FULL THROTTLE for the first few tanks!! Bring it back each empty tank to shore and let it cool off entirly. This is my way I run my enignes in and they run like hell even after 2 years.
