My mates corribee had a Vire 7 and we renewed the impellor on it, It wasn't hard but we had the engine out of the boat at the time I seem to recall it was at the back of the engine . The good news is that is was fairly straight forward to take the engine out and put it back in Scott

Yes it is possible to replace the impellor in situ, but not easy. The water pump is low down at the back of the engine, It is held to the gear box with three bolts. Best to replace with stainless if not already and to use allen head bolts since they are much easier to drive than with a spanner when working virtually blind. With the access panels in the side panels removed it is possible to slide down into the quarter berths and get a look but for someone my size this was difficult and I relied a lot on mirrors. When the water pump cover comes off, the impellor can be removed but be very careful since the impellor shaft is keyed to the shaft using a Woodruffe key (small bit of steel in a half moon shape about half inch long) easily lost into the bilges. The main problem is that there are so many bits to get back together. There is a spacer under the water pump cover with gaskets either side and the cover has two water connections for flexible pipes one the inlet which is relatively easy to deal with and the other (about 2in long) which connects to the exhaust jacket. I found that it was better tp forget the water connections when first assembling and conncentrate on the impellor, spacer, gaskets and Woodruff key. The water inlet is easily connected but the difficult connection is the short tube to the exhaust jacket. There are two ways of dealing with this short pipe. (1) Use a pipe just long enough to do the job but short enough to squeeze onto one end and then slip the other end on, and (2) Use a much longer pipe and connect to the pump and then form a circle and connect the other end to the jacket. Use stainless jubilee clips. The place to get all spares and helpful information is Nick Le Fauvre of www.s109316956.websitehome.co.uk/vire7/. I found Nick to be very helpful and he sorted out my engine after which it was very reliable. If you don't have an engine manual, Nick can supply these. I also remember a useful set of instructions from him on the replacement of the impellor. I cannot find these on his web site and I gave my version away with the boat when I sold her. It is much easier to do all of this with the engine out but this in itself is time consumming. Exhaust removal, prop shaft removal, engine mountings removal. The engine itself is not that heavy and can be lifted by hand. I always replaced my impellor in situ.
The links provided by Paul Harrison above are also very helpful.
Good luck.

Hate to sound smug but our BETA engine was soooo much easier, expose engine ( remove companionway step), select screwdriver , unscrew impeller housing cover , replace. Job done in 15 minutes.
the engine anode however took slightly longer as this WAS at the back of the engine, why are "Service" items so difficult to get to? it does nothing to encourage routine maintenance
