Minimax Hydroplane (SeaFlea)

Posted on February 11, 2014   

Literally two pieces of plywood nailed together, painted, then crammed under a 9.9 Evinrude engine with a classic Aeroliner Half-circle steering wheel. The ultimate father-son summer project. Works best in calm weather, since while in plane, the bow rides roughly 3" above the water, and clipping a wave will cause submarining and an interesting trip to the bottom.

  • This boat is now 4 years old. It was built in the summer of 2010 by my father and I as a small summer project. I was 16 at the time. The initial concept of a Seaflea is low cost, low power, high speed, much fun. Even with the small 9.9 1988 Evinrude, if one balances the boat properly and reaches plane, this boat can easily hit 60kph. The point of these things is sheer fun. Which is why I discovered if you flood one side chamber and slam the wheel, you can actually drift the boat. It's basically a Jet-ski, but people like it more since it's interesting, colourful, and not obnoxious sounding (except when you drill into the exhaust chamber). When I built this boat, there were none other on my lake (pop. 200). Although, many current cottagers came to this lake as children, and had Seafleas in the '50s and '60s. Since bringing this boat back into the community, I have encouraged many to think about building their own (usually those remembering how fun they were as kids), and so far one family has.

    These boats are very noticeable, and I have been pulled over many times (if they can catch me) so I can be asked, "what is that?" or, "where did you buy that?" It certainly turns many heads, and it was a great project for my dad and I.

    This boat has used 4 engines over it's 4 year life.
    First engine - 2004 9.9 Honda 4 stroke - too heavy - rode on the cav plane and made it uncontrollable.

    Second - 1991 8 Mercury 2 stroke - great engine, light, and torque-y, but has an issue with the carburetor jet (since fixed), and underpowered.

    Thrid - 1978 9.8 Mercury - more power, great sound, but only had a stock 2 blade prop and sat very high.

    Fourth - 1988 9.9 Evinrude - Great power, tuned carb, tuned 3 blade prop, big gas tank, sits low, lots of parts (current engine).
