If I had written a review right after trying it the first time I would have been 1 star because I broke the bolt. I replaced the bolt with a grade 8 bolt and nut and tried again. Same impossible compression. This time I stopped and looked at what was going on. My transom is only 3/4 thick where the drain is. The pieces of this tool stack up to a hair over one inch. I bottomed out the tool before it could flare the end. If your tramsom isn't at least that thick, you won't be able to flare the end. Once I figured this out, I was able to finish the flare using half of the tool and a fender washer. No damage to the working parts of the tool except the bolt.So, measure the tube and cut it square adding about an 1/8 for the flare. The tube needs to be at least 1 3/16 long. Or get creative and use half of the tool.My wife is wrong, I don't need to go to the gym because I was able to break a 1/2 bolt with hand tools.
