I'll be working on repairing the rudder on my Sabre 30 this winter. I can't find any reference on which foam density to use (there is 2lb.,4lb, 8lb) I was thinking of ordering the foam from US composites. My son uses alot of their products when he customizes his jet ski. Looking for your opinions.Thanks!
I did that a few years ago on my Columbia 32, I would think it would be similar for a Sabre 30. I have the original manufacturer's specs and it was the heaviest foam that US Composites offers. I forgot what it was, I seem to remember 15lb but could be wrong; I am positive it was the heaviest (and most expensive) they have. It seemed similar to the original foam that I replaced completely.
And yes, you have to do it in several layers, otherwise you get incomplete filling.
