ports
I was going to go with the tri matrix ports for my 83 H30 but there were three sizes of ports on my boat. Trimatrix only cones in two sizes. One of the sizes was about 2 inches bigger on both sides than the Tri matrix ports came in. I didn't want to do any extra glass & gel coat work so I went with the same ports that came on the boat. I ordered them through the hunter owners chandlery from the link at the top of the page. the total was around $1100 for all of them. Since all of my ports leaked around the frames, I had to do some core work and some minor glass work, but they turned out really great. No more leaks! It was a pretty simple project, but took alot of time. I now have 9 opening ports and plenty of fresh air in the cabin.
