Re: mercury 150 xr6 (how to get lower unit off
5 studs and 1 allen bolt. Studs are,
1. In front, nut on top. (1)
2. 1/3 back, nuts between the cav fins. (2)
3. 2/3 back, nuts on from bottom. (2)
4. under the torque tab/ electrode. Seal on top (maybe) allen bolt holds on the electrode, then from bottom allen bolt into the mid.
Usually take the top nuts (#2) off last. LU should just drop off, sometimes you have to fight with them. Depends on corrosion.
