New to this site and motor. Does water supposed to come out of the prop when running. When the motor is started there is no water coming out of the 2 holes below powerhead for about 1-2 minutes. Once the water starts coming out I get a overheat alarm. When the engine is running you can look down and see that there is no exhaust pressure coming from the prop (bubbles ect.) water pump is working as there is a firm stream from pisser. Exhaust blockage posssibly? Motor sat in the up position for about 3 years till now. Any ideas would be appreciated
