New zincs..
Had my bottom painted last week and the yard also put a new zinc on the
propeller shaft. I'm sure it doesn't sit 'right' and that I can feel the shaft wobbling at anything over 2000 rpm. What can I do about it? Molesworth |

My boat has a 1" shaft but the only zincs I can buy are 25mm and they do not sit right. I get over this by bolting them on tightly and then hammering them together tightening the bolts as I go until further hammering fails to loosen them further. The zinc is fairly soft but you must of course hold a heavy weight hard against the back of the zinc to absorb the hammer blows and protect the shaft and its bearings from stress. Done this for several years and never had any problem with vibration or loosening. |
