Because of the short driveshaft housing putting the powerhead close to the water, the exhaust is directed to the top of the powerhead before looping down toward the exhaust housing. Any water leaks in the exhaust cover tend to puddle in the bottom cylinder. Any leaks in the bottom main bearing seal can be distributed through the entire powerhead by the built in re-oiling system and is bad news. . . Good to see you at our Yellow Jacket meet.
