Replacing the port bilge blower 370 Voyager

[LaBomba]

While on a one week trip this past week I decided to check all the bilge blowers as I could only hear the generator blower from the bridge. Upon inspection I found out that both engine room blowers were not working. I first ruled out the switch and breaker and found power to the blowers so assumed both were just burnt out. I arranged to have two blowers delivered to the marina we were at and then installed the starboard one as access was somewhat easy. My problem now is getting to the port side blower as it is outboard of the port engine and behind the water tank and under the fridge and cupboards so no access from the top. i'm not sure it can be removed without removing the hot water tank?? Has anyone done one of these??

I have a similar problem in my 530. None of the blowers are working. They are wedged between the fuel tanks and the hull and are essentially impossible to reach.
