    Flo-Rite Install

    What size hole saws do I use for the 2" and 4" flo-rites?

    My 4"ers required a 4.5" hole saw bit; perfect fit. Bought the saw bit at Lowes for ~$35.

    James, I used a 2 1/2" hole saw to install 2" flo-rites on my ski Sat.

    James, You will also have to grind the fiberglass on the inside of the hull until it is about 3/16" thick so the clips on the flo-rite will catch and hold it in. It is a messy job. I covered my motor and filter screen up with a towel and used a shop vac while I was drilling and grinding and still had to hose the dust out of the hull when I was through.

    Ouch Scotty! That's one way to do it, but man what a mess. It was messy enough just drilling the original hole. For that, I taped a big garbage bag inside the hull, and that caught most of it. The fiberglass is nice and thick, but I didn't want to have an area compromised by grinding it away. The Flow-rites have three tabs that stick down from it, and each tab has a little lip off of it that's meant to clip underneath. Since the fiberglass is so think, what I did was cut off the lip of each tab, and cut away a lot of the excess fabric. The three clean tabs now fit perfectly in the hole, and I used plumber's glue to secure it to the hull.

    Hope this helps-

    I thought about cutting the tabs and using silicone but when I drilled the holes the thickness in the holes varied a lot so I didn't want to have to try and cut tabs different lengths to match the thickness. It wasn't to bad. I didn't grind big areas just enough for tabs.

    Thanks for the help.

    Oh, I see. A little Dremel tool could be used to grind away just enough in the right place to allow it to clip under; I thought you meant that you used something like a big belt sander to thin the entire area under the hole.

    When you say "didn't want to have to try and cut tabs different lengths to match the thickness", I didn't have to worry about the length of the tabs. I left the tabs the length they were, I just took off the lip that allows it to clip under something. Then the Flow-rite with the remaining tabs sticking down slid right into the hole, which keeps it from moving side to side, and the glue keeps the Flow-rite from popping out.

    I will try that next time because I am going to add a couple more 2" and have a 2 1/2" ordered to go in the blank where the gas cap would go on the other side. You have a boat so you have to find other places to put them.

    Thanks,
    Scott
