Tom new owner of 150cc with only 2 rod holders. After watching video and learning the construction of my boat I like some others took one rod holder out to see why it does not drain. Saw the plastic cap taped to the end and realized Triumph decided it was not necessary. I am now trying to install 2 more flush mount rod holders near but forward of the transom. Using a deep hole saw I successfully am about 8" deep and I hit a black plastic hose 1" diameter that is running horizontal. I am hoping this has something to do with the foam injection??? I can not see where it goes to. No hoses like it exiting into the transom cavity. Thought I would poll this knowledge base before I drill through it which will sever it completely. I saw other posts without any mention of this obstacle. The 150cc is pretty small so rod holders are a must have!
