Jet Ski Jon Boat
« on: October 24, 2012, 02:24:39 PM »
I've been playing with Jet Skis lately with the idea of doing a Jon boat conversion. Long story short, I had two Seadoo SP's and finally got finished combining the best of both into one that is complete that I could run before I decided on using this particular drivetrain for the conversion.

Today was the water trial, and it passed with flying (almost literally) colors, I see the appeal these things have. They are the sport bike of the water! Tons of fun if you are into getting wet, It was fun but I'm more into staying dry. Bottom line is I have a solid performer to use as a donor now.

As things progress I will update this thread so those who wish to follow along can see how it's coming along.

This is my video from today's test. It is a 96' SeaDoo SP with the motor from the 94' SP I also have. (587 Rotax 55hp) The 96' motor ran, but had lots of salt water corrosion and had low compression.

I too have been considering a cool little aluminum jet boat project since I looked at some video's on Youtube last year. Search New Zealand mini jet boats. These guys really know what their doing. They build some really awesome 10-11 foot boats out of aluminum, and put some serious motor's in them.
Watch the entire video. Very Impressive little boat.

Yup, I'd seen that video along with countless others during my marathon search for info and ideas on doing this. Very cool boat for sure, also one of the boats I'd seen that made me think about building something myself. I love fishing out of my Mokai, but there are times when I'd like to catch more than a few fish and having something big enough to keep a ice chest, that could go 30, while using less fuel than my big boat. It would be highly maneuverable and shallow water capable while on plane too.

Haha Yes, although I prefer FrankenJon.  ;)

Finally got the Jet Ski hull trimmed down to the finished size.
Next step is to finish marking out the cutout in the Jon and get some more chop chop action going.  >:D

I cut out a slice from the forward side of the jet ski hull to use as a gauge to shape the Jon boat hull to fit like a glove. Next to mark out hole locations and plan the wedding.  :D

I'm not glassing it in.. It will be sealed with polyurethane and bolted in.  ;D

Expanding foam. excellent idea and even easier. I have built whole boats from it then carved the shape and glassed it.

Glass and foam both have their place and purpose.... but, if I'm going to take this boat down the river at 40+ mph I want bolts tying everything together... Lots of them.

Got all of the holes drilled and reinforcement straps made today. Once everything is test fitted I'll take it apart and put sealant down. Things are starting to take shape and I'm liking what I see.  ;D
