As far as overpowering goes, will the boat hold it? Probably, more than likely. But, in the event of an accident where you are liable, the lawyers will have a field day. You better not value your stuff and money. Now, chances are, with a 14 foot jon, you aren't going to get into a deal where you have seriously injured someone, and will be held liable in court. Also, you may have issues with insurance as well. Most people probably won't insure a 14 foot jon, as homeowners insurance often covers it. But, if something happens, even if it is power unrelated, (someone rear ending the boat on the way to the lake) the insurance company may try to use the fact that it is overpowered to worm their way out of paying.
Your decision. I am not advocating either way, but I will say this, their may a boat or two behind my house that might be overpowered...... :lol:
You are paying through the nose for the Lowes/Home Depot aluminum angle aren't ya? If there is any sort of steelyard or metals supply place near you, I will almost guarantee that you will pay MUCH less for the same stuff. Or, some scrapyards sell used stuff, and you can find brand new, or almost new aluminum that people no longer have a use for, and scrap. There is probably 700 feet of 1 inch, by 1 1/2 aluminum angle, 1/16 thick, in 16 foot lengths, still bundled from the factory, that someone scrapped, and is now being sold for surplus aluminum price at my local scrapyard. Picked up 3 sections last week. Just trying to save you a few bucks if possible.
