Re: Motor mount replacement
The thing with the PSS seal is that you must keep proper pressure on the sealing collars.. that pressure is provided by the bellows hose against the (fixed) position of the motor and gear.. remove that restraint, the bellows follows the coupling forward and
So first you need to 'seal' the seal. This can be done with good tape sealing the gap between the collars.. but it sounds like you have a V drive and that makes access a real PITA. - Not to mention the 'direct lift' that that applies to the shaft and seal. In fact you possibly can't easily do this in the water with a V drive and a PSS seal.
You could try to loosen a mount, both on the adjusting stud and at the engine bearer beam, and lift that one corner just enough to slip the mount out... and reinstall the new, doing them one at a time. Alternatively, if the mount bracket attached to the motor is removable, support the engine, remove both the mount and the motor attachment bracket, change mount and reassemble.
If you do tape the seal for this job don't forget to remove the tape before engaging the gear again...
Best of luck...
