I was on the lake one day and noticed that there was not much water coming out of the exhaust on the motor. I changed the impeller and hooked up a hose system and water flows through the prop like butter but the other is just a drip drip. Should I test it on the water just to make sure. I tried to find the tubes that go into the motor for the water but it looks like it goes in from the bottom. So getting to those may be a pain. Thanks for future replies. (boat newb)
