Spartite 2000 mast wedge replacement system - need info
Spartite will replace the rubber blocks at the partners. It does leak water. It is also damaged by sunlight. To protect from sun and reduce water leakage, cover with mast wrap tape or mast boot. I also silicone around the mast-spartite joint. There should be no "shock loads" from the mast to deck since the mast will not move laterally in the partners - a big improvement over wood or rubber blocks. It should not matter how large the mast is, only the size of the gap between the mast and deck. You will need to estimate how much to use to fill the space per the instructions.
Great product. Fairly easy to install. Have had mine for 4 years - CAL40.
