You have to remove the drive and the bellhousing. In case you are curious, just try to get to the clamps on the hose without removing them. It will be obvious very quickly what has to be done.

To Tommays - BUY A TICKET TO WATCH - did you read -water inlet<br />tube problem ? - the guy that asked for help tried it - and it worked.<br /><br />Any certified Merc mechanic from the 70s - 80s - has known this for years. <br /><br />BUY ME A TICKET from Ft. Myers, Fl to Long Island, and I will teach<br />you - in 45 minutes. <br /><br />.

well now i have had a front row seat and it was a good show with a good plan :D <br /><br /> (You can change the fitting with out removing outdrive. We also<br />always change the water hose - they get old, stiff and a small kink<br />will cause over heat at high rpm. The hose is $10.<br /><br />Takes 2 men. Inside boat remove plate held by two bolts.<br />Work grommet out with screw diver and long needle nose pliers.<br />A little WD 40 helps.<br />Note - location and position of upper hose clamp on water hose,<br />this is important - so as screw on clamp will not rub on drive shaft bellows after its installed.<br />Cut water hose about ½ way between transom and outdrive.<br /><br />While inside man pushes, with long skinny screwdriver - Outside<br />man wiggles and pulls- hose and barb will come right out.<br /><br />Install new barb- hose clamp has to be exact location as previous.<br />As outside man pushes hose and barb up to hole in transom - inside<br />man lines up barb with screwdriver, - as soon as barb starts into hole - get hold of it with needle nose - wiggle push - take your time - 2 or 3 tries - it will go. Install grommet and plate.<br /><br />Hose - raise outdrive about ½ way - Remove exhaust hose at outdrive to make room. Note exact position of clamp on<br />outdrive hose barb - remove clamp - split water hose end with a utility knife and pry hose off. Clean barb with sand paper - real clean .<br />Grease barb and inside of hose - place clamp on hose end - slide<br />hose on barb - tighten clamp - this clamp is the hard part.<br /><br />Sand exhaust flange and exhaust hose - real clean - smear bellows<br />adhesive on flange - as one man pushes hose on and holds in place -<br />2nd man installs clamp.<br /><br />I have done this job many times - takes 45 minutes. Water hose comes 2 sizes - 5/8 and ¾. Be patient, it works.<br /><br /><br />Five minutes of thinking - saves hours and dollars.)<br /><br />a better way by elpaso<br /><br /><br />i got to wonder why its kept a top secret method ;) <br /><br /><br />tommays
