Getting ready for spring . Changed the LU oil and drained out any remaining water . Put on my ear muffs and started the motor. Sounded great and started with only one crank. Now I'm concern bc I don't see any water coming out of peehole. What should I be worried about? I let it idle for about 5mins still no pee. 1995 3.0l merc 225hp any thought will help thanks
