hi there everyone. im new to boats and the engines that push 'em.my motor is a 1990 force 120 hp with b at the end of the model #. ive noticed some exhaust coming out of the pee holes on the back of the motor. i noticed it getting in the water to swim right after shutting the engine off. i also noticed it right when i started the boat before the water came out of the pee holes.is this normal or is there a leak in a gasket letting exhaust into the water? hmmm. thanks
