I don't know how many of my fellow teener fans are into boating, but I've had a boat project in my head for a couple of years now and I decided to use some of my 914 down time to attempt a prototype of my dream boat. I've wanted to build a shallow draft fishing boat powered by a Subaru auto engine and a jetski pump. To prototype the idea I built a smaller version powered by a complete Yamaha waverunner driveline. I took a 16' Carolina SKiff and a 1994 Yamaha VXR Pro and went at them both with a (IMG:style_emoticons/default/sawzall-smiley.gif) and this is what I came up with:


It started as this.........

It is so damn fun to drive it's hard to keep a grin off your face when cruisin'

It's joystick controlled and it'll run about 35 - 40 mph in about 4" of water! Here's a pic of the initial sea trial before I built decking and such. I sat on a chunk of plywood just to check it out........

This is my next part of the project. I fabbed a reverse gate (out of PVC elbows!) for the pump, but now I need to fab up a cable/linkage.........

Sorry to eat up server space with non-914 pics, but I though some of you might enjoy the tinkering aspects of this project and hell, I know a few of you know the joys of itchy fiberglass work!! (IMG:style_emoticons/default/w00t.gif)

Right on! 35-40MPH has to be a blast in a boat that size.

That is awsome. (IMG:style_emoticons/default/smilie_pokal.gif)

Its great that you made it work so well.

I spent an entire summer once designing and building a HPW (Human Powered Watercraft)

Had dual hulls, aluminum frame, and surfacing Rolla propeller. Was faster than a 2 man shell, for a sprint anyway. I'll try and find a pic.

Dude I just got wood over that project of yours! That ride had to be a blast to take out for a POC check. Ain't imagination and vision a beautiful thing?

BRAVO (IMG:style_emoticons/default/smilie_pokal.gif)

Thanks for the positive feedback! Other than the itchy scratchy phase of the fiberglass work, this project was really cool to tinker with. As a prototype, I tried to re-use as many of the stock yamaha pieces as possible to streamline the project and keep the investment low. Someone gave me the waverunner for free and I picked up the skiff for 400 bucks in a pretty rough state. It took about 3 weekends to get this thing seaworthy, that's rapid prototyping....thank god for coffee!!

The boat handles incredibly well and the joystick method of control is really cool. I'm surprised more jet boats don't use it.

A side benefit of this design is the perplexed looks you get when rippin' past someone with no visible motor. Everyone knows this popular boat as an outboard and it blows their mind to see it go rippin' by with nothing on the transom.
