Weeds clog the M bracket openings and the engine mount area at an unprecedented rate and drop me to less than half speed. I clear the weeds manually and it works fine until I encounter more weeds. I do not have to be in heavy weeds for this to happen, it is cumulative with scattered grasses or weeds. I am not sure of the solution but I think if the openings were sealed off this would drastically reduce this problem. Also, I thought with the saltwater edition, elliptical tubes, lifting strakes, and the rough water package that the under-deck would be sealed, and all welds on the lifting strakes and foils would have a continuous weld to prevent salt water from getting into areas hard to flush. Anyone know the answer to what comes with these upgrades? Shouldn't the entire under-deck including and welds be fully sealed? In Florida's fresh waters it is against the law to transport ANY weeds from one body of water to another. I am powered with a VMAX SHO 115 and the engine collects very little weeds and they are easy to clear. It is just when the boat collects the weeds the performance is greatly reduced. My boat is a new 2017 21' SSX. Any one else having this issue? Any ideas for a solution?
