I mated a Sea-Doo 717cc powered engine inside of a 1448 johnboat almost 3 years ago, this review was just discussing longevity of engine type and its failure and basic set up. Comment like and subscribe for more videos of the long term jet Jon build.

The "Seadoo powered Jon boat longevity review." video is part of the category, which contains similar videos like this one.
If your not using a seadoo hull you will have to find some way to seal the shaft that's why it's nice to use a seadoo hull or at least replicate it in aluminum so you can use the same seal.
Ether will work for this application the v makes it a little better for speed and cutting chop. You really have to decide what kind of water you going in. I only do shallow water 2" to 5' deep only in rivers if I take my boat on a lake with chop I can't get up to speed because of cavitation because my pump sits level with my lower hull. If your doing a lake boat then you need to set the pump as the deepest part of the boat to avoid cavitation.
Thanks for watching!
First off the 717 has 85hp so stepping up to a 787 2cyl that has 137hp is cheap. All the pumps are fairly interchangeable so getting a reverse would be easy they are on eBay all the time for a good price. You don't need to buy a seadoo boat as the pumps and engines are the same as a actual seadoo.
If you have the ability to fabricate the aluminum intake grate and your boat can be welded on (old aluminum doesn't weld very well) then that would be a good option but just remember you need ether a fully clear area on the hull from the front to the back so no ice runners or you need a spoon in front of the intake grate to push air bubbles away from the intake.
Happy modding and feel free to run any questions by me I'm about to start building a 1760 from pure scratch for my next boat.
