I wrapped a bungie cord around my muffs to make sure they hold tight since Force put the dang inlets on the torpedo part of the lower unit and w/ that being rounded the muffs like to move around. The water only spiutters out of mine when the idle is raised other than that it looks more like a light mist. This is normal and you can see other post here w/ Force and this sputter uniqueness. By the way I change my impeller every year.
Water and exhaust come out of two places on your engine. One is the exhaust relief holes on the middle leg and two the snout that is behind the prop. You should always see water and exhaust gases coming from both. The relief holes may only appear to be spitting water as most of the water and exhaust take the path of least resistance and exit the snout when running on muffs.
Help. 125 hp. Water not getting to thermostat. Removed lower unit and connected water hose to water tube. Water is not getting to thermostat. 1984 motor. What could be blocking it.
