Raising the transom height?

7 posts in this topic

I have a Jon boat I use for duck hunting with a long shaft 15 horse. Was wondering if anyone knows of a simple way to raise the transom to get the motor up to normal operating height. It should be raised up about 6 to 8 inches.

Thanks for any suggestions,

Pete

Short shaft is 15", long shaft is 20", you should raise your transom just 5"

Thats really going to depend on how your transom is built.

You should be making up the difference of a long shaft which is 5". You shouldn't add 5" either, you should be replacing the entire section of wood with a laminated beam. Before we go any farther, if your transom has the drop then it might be doable, if its straight across then I wouldn't attempt raising the transom and would use the proper length shafted outboard. You'll have to replace the aluminum cap over the old transom with a straight cap and that cap will need to be tied into the corners. You might also have to fabricate a new(longer)transom brace. A couple pictures of your transom would help here.

I believe you can get a "mini" jack plate to raise it. The plate will mount to your existing transom and then the motor will mount to the plate. Do a google search on mini jack plate.

They are around $100

PeteS, Would there be a chance that your long shaft is actually a short with an extention on it??? Maybe you could take the extention housing and the shaft extender out and make your motor a shortie.

Thanks for all the great help. The transom goes straight across and the motor is a true long shaft... no extension.

I'm looking into the jack plate idea. I just hope it will lift the motor high enough. The transom height on this boat is low. I think a short shaft motor would be too frown.gif long.

Thanks,

Pete

lol, you might need a butt seat to steer the tiller wink.gif

I'm not sure how safe it would be to use a long shaft in your situation.

      Quite abit of new tackle, along with some different plastics options this year. Some of the new products have proven itself on soft water while doing some recon during the past few weeks, fishing first ice spots. Fine tuning "spots on the spot" can pay off big time, before fish become spooky from noise of crowds, which more times then not, makes them less willing to bite, and can make them move to other key locations nearby.

      I'll bet this lure will get a lot of bites! It may even catch a few fish! Does look interesting. Cliff
