I'm getting ready to pull the boat, paint the bottom and do some engine maint. How hard is it to change the leg bladder? Can a competent machanic do it with a shop manual? There is a resident mechanic at the yard where I will pull the boat. I have seen a German video on youtube and it doesn't seem too hard. The only other option is sail up to seattle where there is a volvo dealer. Fyi, it is a 2005 model and it seems to have worked well for the last 10 years. The other project is to change all the fluids.
