My boat is a 1986 140 mercruiser I/O with what I have been told is an early Alpha outdrive. Problem is, when running with muffs on,water is dumping from above the exhaust bellows, so I assume the hose that sends the water to the engine is cracked,(looks badly checked). Do I have to pull the outdrive and bell housing to replace this? I removed the exhaust bellows and can get the hose off the lower end, but it disappears somewhere up in the top of the bell housing.I also removed the hose/cover/bushing from the copper pipe behind the engine, that goes through the wall to the housing thinking hose might pull down from the bottom.....nope.......am lost now.<br />Thanks in advance for any help you guys can provide.
