Thank God now I know what I'm looking at.....
1) Why the diff colored things on top?
2) Why the holes into the bottom of the swim platform? Wire could go thu sterndrive holes?
3) Tabs should be functionally fine where they are at or what is a k tab?
#1 - I'm using lower density foam for less critical parts . . . spacers, etc.
#2 - I need to be able to reach areas inside the swim platform cavity to install bolts.
#3 Scott replied about the K-planes. . . They are more narrow, but longer. The cost is above my allowance.
