Jet Jon

32. The gooves running down the bottom of the Jetski hull are good for Jetskis, but bad for installing them in Jet Jon boats. You could mix a ten pounds batch of filler or you could use spacer strips. I chose scrap wood strips, if you are installing in an aluminum or fiberglass hull you can order high density polyurathene strips from "Industrial Stuff".
The strips I cut are 1" wide by 1/2" thick.
33. After working so long on the Jetfish there was no way I was going to cut the bottom without making a template. Bottom Template Drawing (coming)
34. Once you get the Bottom Templat completed you can do a trial fit with the wood (or other spacers in place). You''ll find this is also helpful for making the transom cutout template.
35. The transom template should have a 1/4" gap all the way around to allow enough space for filler. I just guessed at the transom angle. (it's not too critical, but be reasonable).
36. The templates really makes aligning and marking the bottom simple!
37. Once cut, you should have an area at the transom where the hole on the bottom it wider than the hole in the transom. This is good - it means you did it right! I used a handsaw to make the bottom cut flush with the transom wall.
38. For a "dry fit" lay the hull spacers in place as shown and set the Jetski hull in place.
39. Now you're getting somewhere!
Ready for bolts and filler!
