Here's a site with Yellow Jacket, Minimax, Minimost etc. They are all outdated for racing but if you're not going to race they would be plenty exciting. Sam

The aluminum boat pics you requested are here. Click on the link in my sig to get the shareaproject link. It is not quite current but is all the pics I have on my computer at this time.

Re: Mini hydroplane?

Several of my buds and I built PM Min/Maxes in the early 1960's. It looked the same as the Glen-L Minimax plans. I used a Mercury 7hp KE with a bronze two-blade prop and open, dry exhaust headers from a go cart engine. Had to work hard to get it on plane, but once there it was a blast. The horsepower race escalated rapidly with one guy mounting a Johnson 18hp and another using a Mercury Mark 25. They did not turn well and the square chines dug in with any kind of chop or wake. Wish I was young enough to enjoy one again. I'm thinking about building one for my grandchildren. You only go around once!

Re: Mini hydroplane?

If you are not planning on actually racing competitively (except seeing if you can blow the doors off the neighbor kid on his Jet Ski) then any of the little hulls you picked out would work fine. The 8-footers are fine for protected waters, but would be a real handful on busy waterways. The TunnelMite would likely be a little better if you were dealing with modest traffic.

FYI - no Hot Foot throttles on any of these - they're kneel down racers. You'd need a dead man throttle (Keller style listed here: http://www.boatdesigns.com/products.asp?dept=677). A kill switch tethered to your lifejacket, in addition to using a spring loaded throttle, is a must.

Lots of things you can do to make them go faster, too. Playing around with props, motor angles, motor height - anything to tweak the set-up - can be a lot of fun.

Play safe!

Re: Mini hydroplane?

Im probobly leaning toward the glen l designs unless i can find a cheaper racing hydro, which i really want more because the idea of flying past big fancy boats and jet skis with a little 9 ft boat sounds, and would look pretty funny.

Re: Mini hydroplane?

(1) is it a bad idea to use a regular throttle with a teather kill switch? i understand the idea of a deadman throttle but i dont see the difference between the 2 if you fly out of the boat.
(2) if i cant afford the throttle and steering system right away, is it safe to just leave it as a tiller for a while?
(3) i have seen the steering systems they have with the cables and pulleys and was wondering if it would be possible it make one and not have to spend a ton of money on one.

sorry for all the questions, im just trying to figure out how to build a hydro without spending a ton of $$.
thanks

Re: Mini hydroplane?

I am building a 24'Powerboat from that company, they have a great rep and great plans, plus the forums are real good for help. I looked for other companys that had boat plans but didnt find anything. So go with them, have fun, save some money, and build that dern boat!

Re: Mini hydroplane?

A simple cable steering system is probably your cheapest way out in that regard. Might have to fabricate a steering bar for the motor as you don't really want pulleys at the transom to get tangled in if you take a digger and end up in the drink. Think simple. The plans will likely have some sort of diagram to aid in rigging. You can probably find old style cable drum type steering wheels at a boat yard with some junkers and clunkers out back. I modified one once by swapping the drum for the mounting bracket so that I could have the drum on the cockpit side of the dashboard. With the limited space available, it's MUCH easier to rig the steering cables if you're not trying to do it behind the dashboard. Cable and clamps can be gotten at your local hardware store. Steering bar can be made from regular bar stock and bolted to the front carry handle of the motor, with a bend on either side to align the hook points to the pivot line of the motor (to keep the cables from going slack).

Aside from the obvious reason to go with a deadman type throttle, they are also quite useful for keeping your behind in the boat! You don't sit down in these things - you kneel. You use your body weight to finesse the boat over waves, around corners, etc. The throttle acts as your "oh sh*t" handle. You hang onto the steering wheel with one hand, the throttle in the other and wedge your knees against the cockpit sides. That's all that's keeping you in the boat. A regular type throttle doesn't give you anything to hold onto. If you hold onto the throttle arm, everytime you hit a wave or shift your weight you'll be moving the throttle.

It's not hard to make a throttle if you have one to pattern from (to get the range of motion correct). A friend of mine made several out of billet aluminum a few years back and they turned out nicely.

Keep in mind - it's not a matter of "if" you flip or get spit out, but of "when".

Re: Mini hydroplane?

A runabout or utility hull will probably be bit more difficult to build, but not significantly. A runabout hull will be much more forgiving in a busy waterway, although it certainly won't ride like a Cadillac - none of these little boats will... They are much less likely to stuff a wave and are easier to turn in choppy water. They are also more responsive to body english, more of a driver's boat. We like to refer to 3-point hydroplanes as runabouts with training wheels... 8). Anyone can steer a hydro, real men DRIVE a runabout...

Keep in mind that some of those jet skis are good for 80 or 90 mph,,d:)

Re: Mini hydroplane?

Hi Bob,
Craig wasn't behind me for long, you can count on that. :|
He's the one who found me my boat when I got into racing. I had driven a couple of Brocs and he knew where one of his was tucked away in a barn in Pennsylvania. Easily one of the best handling, most forgiving hulls I've ever driven...
Actually, that's an all Team Broc picture, now that I look at it. 97-A was his daughter's boyfriend (at the time), 110-J is Craig, 112-N is me, and 110-N is a friend of mine who bought one of Craig's kits after driving my boat.

Scott, we only see Craig about once a year at the marathon nationals that are held on our inland waterway here in n.michigan. You should make the trip one time it's a great weekend and a great race--Bob

Sorry for jumping on your thread Bass-A-Holic--Bob

Re: Mini hydroplane?

Hi Bob,
One of my Dad's favorite stories was racing THREE marthons in a single weekend in Michigan back in the 1960s. Apparently there were three scheduled over the course of a Labor Day weekend and he made, and placed, in all three. He raced 36 Class with the West Bend 35s. That's probably why he has trouble walking now...
The Top-'O-Michigan is one of the things on my Life To-Do List. Someday...

Re: Mini hydroplane?

Would that glen l runabout be hard to build, and if real men drive runabouts then how much faster will they be than a hydro?
again, sorry about all the questions i dont want to build a boat and then decide i dont like.
thanks
