Looking to put a fish finder on this puppy. Willing to spend around 250 bucks. What do you guys recommend? Also I know nothing about fish finders so how would I mount this thing? On the transom?

Thanks

There may not be a place to mount a shoot thru on that hull and you may have to transom mount it.

Just about all new boxed units are shipped with a transom mount transducer so you will have all you need for installation.

Just get the most vertical screen pixels in your price range.

You may also want to look at getting a gimball mount for mounting the unit to the console if there is not already a port precut in the dash for it.
