Now I have a massive issue, I purchased what I thought was the right new lower unit and it is right except one very important thing, and that's the length!!!!!!!!
I was told it was an X long but it seems to be 6 inches shorter than the X long so it can only be a Long, Mercury won't take it back as I purchased through a reseller and it was shipped into the UK so I am now stuck with a new prop, new lower unit that won't fit... Grrrrrrrrrrrr
Does anyone have any suggestions? I have been trying to locate a Mercury 5" extension sleeve 78147 but can't get one in the UK. Plus if I got one of those I would also need the water pipe, gear change shaft extension and longer studs, which are also not available in the UK. The only other option I can think of is to get a NEW long shaft and bearings and replace that in the new unit (voiding my warranty).
So either way I am totally stuck. I got up and 03:30 this morning travelled 120 KM to fit the new unit to find out it was wrong. I'm so so annoyed right now I feel like just giving up.....
