 Topic: Rudder plate leakPosted: June-21-2018 at 10:06am |
|
I have a leaking rudder plate on my 1985 Ski Nautique. There also seem to be some stress cracks around the plate inside the boat.
I plan to remove the plates inside and out and seal with 5200. Any thoughts on whether I should be concerned about structural damage in the rudder area. Thoughts on moving forward from here. |

Drop it, clean it up and inspect. Take a grinder or sander and see how deep the cracks go. If they are into the laminate then a laminate repair will be needed. Look real close at the stock log to plate intersection for cracks in the casting.
BTW your rudder and strut are (or were) probably bent. |

Why not add a few layers of fiberglass cloth & epoxy resin to the inside?
Just grind off the gel coat 1st. While the glass is wet, you can put a pc of plastic sheet over it & lay a flat pc of plywood on top to encourage flatness. |

Is there any craziness I need to prepare for with this project, or is it pretty straight forward?

i thought there was a wood backer for the rudder through hull, min had one that was waterlogged. I replaced with coosa and ran it to transom and laid up some proper glass or over kill glass over it and lapped stringers and transom

An accidental thing I found was when I wiped the fiberglass with solvent (I think it was mineral spirits but not sure), the cracks stayed wet after I wiped the excess off. They were very easy to see.
Kinda like dye penetrant but much cheaper. |
