I have never had my 1978 Johnson 115HP engine apart, but would imagine that there would have to be some sort of seal between cylinders in the lower end, to keep pressure pulses separate for cylinder charging. (If I'm wrong>>>please tell me)<br />How can you tell if these seals are bad/leaking??? Can you tell without a teardown?? I would imagine that it could be a cause of rough running, weak throttle responce & all around lower power. <br />I always read about checking the compression, and cleaning the carbs, ect... But have never heard anyone suggest a problem with lower end seals??? Do they never go bad??? Are they just a figment of my imagination??? <br />
<br /><br /><br />Thanks for any help.<br />
