Hello I have a 1993 4.3 mercruiser V6. The outdrive is a alpha one gen 2. I am planning to take my boat to Ocean City MD for a week in the summer and plan on leaving it in the water. My boat is primarily a fresh water boat, so I though it was a good idea to replace it with some new anodes. I ordered a anode kit for my alpha one gen 2 and I can not find the locations for some anodes. I am having problems with locating the prop shaft anode. I removed the propeller and the thrust washer, but there is not place or room to screw in the anode. I also noticed that the power trim anode do not have a place for them. I would have to drill and tap the hole for the power trim anode but I can not figure out if I could get the prop shaft anode in.
