There are two sensors on the top rear of the motor under the cowling. The left one is hooked up with a small grey hose to something, I am not sure what, but the upper left one has the sender, but the small grey hose is not hooked up to it.Can anyone tell me what these two sensors do and are they critical to the engine.<br />ALso, I have the alumimum 14.5 x 19" Pitch prop on a Hurricane 232 O/B what stainless steel prop would be best to use, ie: Solar Titan
