not peeing replaced water pump, but now it is not peeing very fast. seems pretty weak. i have blown the system out. This motor has been sitting for several years and it fired right up first time i tried. Only thing i did was spray some penetrating oil in cylinders and hand moved them. Also the water coming out is kinda warm but not hot. in a bucket no muffs. Thanks for your advice.

Your thermostat is probably stuck partially closed - ordinarily it closes when cold and fully opens when the engine is warmed up

thanks guys. before i replaced water pump. after i removed lower unit i hooked hose to intake pipe and shot water thru engine and it flowed really good. so I know it isn't restriction but wouldn't think it would be t stat either. Thanks for advice.
