Re the water temp - I would have though a key issue is the rate of water exchange - what did you have fitted prior to the Volvo - was it an ordinary stuffing box with greaser? if so then remaining grease in the stern tube may be restricting water exchange - even at the best of times with any length of stern tube the rate of exchange must be fairly small.
Yes, I think that's a likely problem. There was a guy on here a few weeks ago who had fitted the Volvo seal but slapped a lot of grease on the shaft before sliding it onto the shaft.
Clearly, the ridge of grease jammed up against the outer, supposedly water-cooled seal, prevented sufficient water reaching, lubricating and cooling the seal.
I've been using one of these for 24 years and have NEVER found the seal remotely warm even.
