    I'm starting a project late in the offseason. I want to rebuild the transom on my lowe jon boat. It's a 1648 mod v that's setup for bass fishing. I've had a 35 hp backwater on there as well as a 30hp mariner on a jack plate. My main goal is to convert the wood transom to all aluminum. I have access to a professional welder. I have a 90hp merc 2 stroke(currently converting to tiller). I know it's too much power but weighs the same as the longtail. Regardless I want to build the transom strong enough to reliably hold that heavy of a motor. If the 90 is too much i will put the 30 back on and wait till the opportunity to buy a bigger boat comes along. Pods are an obvious addition to this remodel. I'm adding photos of the transom and looking for some input on how to go about cutting the back plate off and removing the corner bracing. Also the splash guard is riveted. Should i drill that out and replace after the new transom is in? I have a design in mind and will add the photos. Thanks in advance for any input.

    I couldn't view any of your pictures except the last JPG.
    I had a 1655 Lowe that I ran a 110 jet on. It was a little wider than your boat.
    The hp at the pump was approx 80hp. That boat was a screamer. Your boat might be a little overpowered with that motor and since its a tiller it might have a lot of rear end squat. Pods should help the boat get on plane faster. Good luck.

    Thanks for the heads up about the picks. Ya the motor weighs in around 300. About the same weight as my 35 longtail. I know the longtail distributes the weight differently and has more of a push thrust instead of a pull thrust. I'm counting on the pods and won't be driving like an idiot in the dark. Let me edit those pictures.

    Did these pictures work. Later next week I'm going to start drilling out some rivets and going to cut the back plate of transom off. Need to go to metal shop for material. Probably going with 2x4 tubing for frame then 1/8" plate for transom. Need to fab a brace for the middle of transom to the floor. Pics/recommendations welcome. Thanks

    Started tearing the back of boat apart. Learned how to remove rivets with a grinder and punch. The transom was worse than I thought it would be. The corners were crumbling. I didn't realize the sides were filled with foam that made things interesting. Next step is too go to metal shop and get some sheet metal for transom, floor, and angle braces. Not sure if I should use 2x4 or 2x6 tubing for transom frame. Also looking for advice for middle of transom to floor brace what to use and where to attach. Any structural ideas to make the rear of this thing like a tank is appreciated. Here are some pics
