You are most likely fitting an Imperial zinc onto a metric shaft. Measure your shaft with a vernier to check. If it is a metric shaft, you may find the prop fastenings are also metric. This is just a guess on my side. When fitting shaft anodes and they are as tight as you can make them, put a blob of sealant into the holes of the fastenings to prevent the zinc being eaten away directly under the bolt and nut heads or else, after a time in the water, the anodes will loosen and give you a bad vibration when under power as they will then spin on the shaft.

All the holes are patched up! Currently fairing the hull....

Here’s another update. After prepping it like crazy I have applied the first coat of primer for the top sides. I thinned the Epifanes polyurethane paint and applied with a roller and didn’t tip, it thinking that this wasn’t needed with the primer. I am a little unhappy with how much orange peel I’m getting. I will try tipping on the second coat of primer.

If your boat is going to be used in fresh water then a Zinc anode is not going to work. It should be magnesium or aluminum. Didn't see that addressed in earlier posts. Sorry if this a repeat.

Thanks for the catch! I will replace it.
