omc water ploblem

[jch7450]

heres two questions<br /><br />1, can the lower unit leak water in it if the impeller was changed and no sealer was put in the bolts?<br />2,if the engine overheated,and the bellows got to hot,can this cause water in the lower unit also?<br /><br />just a thought...it's a cobra

jch,<br /> 1,no.we use sealer so the bolts will be easier to remove next time.<br /> 2,no.<br />I suspect you have a bad seal in the gearcase.Pull it (the drive) off,presurize it and submerge it in h2o.Hopefully you'll see which seal is bad.Use to just tear them down for a complete reseal,but with today's costs,and cobra getting hard to get parts for,I suggest the shortest route.<br /><br />DHP

Check the ujoint bellows for water, if it leaks, there is nothing left to keep water out of the drive.<br />Also when pressure testing the drive, if you don't have anything big enough to submerge the drive in, just get a spray bottle and put a little dishwashing liquid in the water and spay the drive. Even a minor leak will blow bubbles.
