    Ok I have a project boat. Its a 20' flatbottom 72" wide. It was originally setup for an outboard. The last owner paid to have an inboard pod added to the boat, adding an extra 4 feet to the boat, making it 24 feet. It doesn't have a motor now. So my question is go back with the inboard or cut the pod off and go with an outboard? I'll be using it mainly for river fishing. Fishing from march to november.

    By the way I did a search on inboard/outboard and nothing that was related to this came up but I'm sure someone has asked a similar question, so any links to past conversations would be helpful.

    An inboard such as a 4.3 will last longer than most any outboard. Parts can be bought at any auto parts store. Fuel economy will be good.

    I say this assuming a boat that size will be used in deeper water.

    She's a bit ugly but I still lover her. The top bolts down so I can take the cabin on and off with just a couple hours of work.

    a couple more. needs quite a bit of work and this aint something thats gonna be done this year. By the time I'm done I probably could have bought something like it for less but I like projects.

    I would just have to wonder about the qualifications of the person who added the extra length to the boat. The stress that a boat goes through with large swells and choppy water could easily break the keel of a boat not done right. I'd sure want to know his qualifications, and if a shop did it, I'd want to know what type a warranty it had with it. It is not really important, your just betting your life and your passengers life that it was done right.

    I'll have to tear up the floor to see but it was welded really well and the aluminum they used was a heavier gauge than the boat is made of. Its been used as a dock pusher so I really looked it over hard for stress cracks in the welds and didn't find any.

    Id go with an Outboard. If you ever decide to fish in the winter, especially since you'd have an enclosure, it would be much more user friendly.
    Like Lawrence said, I would be cautious of the add on. Judging by the pics, which only tell so much, it looks like a pretty professional job, but that is a pretty major mod.
    If it were mine, Id keep the enclosure, just take a few feet off of the back side for more room when fishin.
    Should make an awesome boat Casey.:good: Hope you can find time to work on her with your 10 jobs.:sarcastic::laugh1:

    Yup! You go with an inboard & you then have the option of adding both heat & AC. A new in the crate inboard can be had for much less money than a new outboard. The initial cost can be the same or more. But once you have your drive & cooling system that stuff can be used on another motor. Regardless what any one says, stay with A CLOSED COOLING SYSTEM!!

    Some of the the points brought up carry some merit. I have built a couple of boats from aluminum. Any time you have a transition of material of different strength you can have a weak or "STRESS" point at this juncture. If it is not done right. Proper back chipping of butt welds & bracing are needed.

    This does not have to be aluminum of different thickness. It can be the welding of say 5052 to 5083. While both of these are marine grade aluminum they have very different yield rates. Simply put in their welded & natural state they are very different in strength. It could cause issues if not done right. All of these issues I mention can be of no issue if done right.

    Have a good welder engineer fella look your project over. Getting the thoughts of more than one would be best. I guarantee you will be glad you did. The information you will get from doing this will be well worth your effort.
    Keep us posted on your progress. Any question I can help with ask away. I know some of the best boat builders in our country.

    That thing looks like it should have cannons sticking out of it.

    Now I wouldn't mind having a project like that. I would have the welds on the add on checked by a pro and put an inboard on it.

    Went and hauled it home today. Looks like shortening the enclosure will be no problem, and the transom is really beefed up with large gussets. So I think I'll be going with the inboard.
