Travis do you know if there are any plans to modify the mold to allow for the rockering/tunnel hull you describe? And also am I understanding correctly that on the Supremes, thanks to the rockering/intake slot, the jet drive is actually protected by the hull, so when you run over rocks and things the jet doesn’t hang down any further than the hull itself?
Hey Zach…I wish the answer was yes…but if so, I think it will be several years before that design is doable by Hog Island. The best alternative would be to consider a UHMW high density plastic jetfoot that is milled similar to aluminum. I have heard different rumors of these plastic jetfoot designs being available for smaller outboards. So far, the only ones I have seen for sale are the larger ones on the Rockproof super jets.
Despite the jet being angled 1-2 inches in the water below than the hull; the boat still drafts pretty good. On plane, I estimate 4 inches draft. I can skate up some zig zag rapids climbing up plunges on rock ledges. The main challenge is going back down, you have to keep momentum to stay shallow–if you ease off the throttle/ you bump. Usually if I see an unavoidable downstream rock encounter, I turn off the throttle and push the tiller handle down to raise the motor out of water, and let the hull take the bump. It’s real nice having the motor lift to push it out of harms way. I also raise and suspend the jetfoot out of the water when rowing back down some bony shoals.
Thanks again Travis !
I want one – looks like a great alternative to a small aluminium boat and a good platform for a cod fishing boat.www.dsaphoto.com

Since the Supreme was mentioned here I’ll throw in my .02. Where Jets are concerned the trick is getting the lower unit completely out, or at least mostly out of the water, even at idle. That said, you also have to make sure your hull is feeding it good clean water. The rockered and jet tunneled hulls on the Supreme make for a boat that will idle almost as shallow as it will run wide open. the specs on mine are about 4 to 5″ at idle, and about 3″ wide open. That IMO is what separates a “jet” boat from a boat with a jet.
You can see what I’m talking about here in the video I did at Cypress Springs. My mother and one of my daughters were still in the boat when I videoed this. Skip to 3.40 to see the boat from underwater.
Mine is a 2007 that I bought still warm from the mold. I’ve put it through all kinds of hell in all kinds of places. Most all the rivers and lakes within a 3 hour drive of my house. The FL Keys, The Gulf of Mexico, The Atlantic, crossed the St. Andrews Jetties, Panama Beach (very spooky). The older it gets the more hell I give it. Look at the bottom in the video. It’s in very, very, good shape still despite the Musky rivers up here that are hell on boats. Line-X only goes so far and really only protects the gel coat. You hit it hard enough and you’re gonna gouge the glass. I’ve watched as the bottom flexes and helps absorb the impact when I run it over logs on purpose. I like that property of fiberglass.
All that said, its not a whitewater boat and I wouldn’t ever try to run real class 2 or above. I’ll leave that for the rock hopper boats and folks with more money then me. One wrong move or malfunction and you, your boat and outboard, and all your gear, are lost. No thanks. And yea you can stand on the bow with no stability problem… It’s 60″X48″. 🙂
Mike that’s a really cool video. Obviously you were underwater–were you scuba diving or just free swimming?
Just a Snorkel and fins. We live in the water whenever we go to Fl. I Took my mom last year after she beat Cancer.
Wow, that’s clear water.
What’s the fishing like ?
I assume they see you coming for miles ??Boat looks good as well, though I can’t find them on the web – I just get ski boats.

David, I didn’t do any fishing there though I’ve heard it’s a good place to fish. We just dove the springs. There are quite a few Bass and panfish, and even a few Alligators in there.
Here’s a link.

Any thoughts about putting a 60/40 on this Hog Island as opposed to the 40/30. Only slight weight difference. I’m wondering about modification to build the transom to 25 inches to accomidating the 60/40 and also not sure if that motor comes with a tiller.
Travis…. Is that Yammy a 4 Stroke? 2 stroke saves you 60-70 pounds… On the transom, while drifting…. That’s huge. Glad you like it bro.
I DO think a 60/40 jet would be better. It is only about 30 lbs heavier than the 40/30, and the extra boost to get you on plane would be a bonus. My only challenge with this is the boat is CoastGuard approved for only a 40hp or below…not every professional installer may be comfortable with the assumed risk. Also, I did not have the luxury of trying out the heavier motor—I wish I did though…I would have probably opted for more power.
Hey Phil, I was thinking the same thing on the 2 vs 4 stroke engines. The only trouble is that most of the lighter 2 stroke engines are older model, and they have to be converted to a jet by a post-market kit. I didn’t want to hassle with the hunt for the perfect, reliable used tiller, longshaft motor, then find a marine mechanic to add the jet foot, and get the height set right.
I strongly considered the Evinrude Etec motors, but they were all in the same weight category as the 4 stroke Yammis. Plus, I hate having to add the oil and deal with the mess. Changing the oil is the only hassle with the 4 strokes–and it’s quite simple, plus they are just so Darn quiet— I really prefer to idle by other fly fishers with super quiet hum of the 4 stroke. I have heard a couple of older 2 strokes that are just plain loud and annoying, not all of them, but some have a “hollow howl” that I would rather avoid.Here are some links I used to compare the motors:
Evinrude Etec 40 hp 2 Stroke–(this would require a postmarket jet foot add-on)—weight: 232 lbs
http://www.outboard-engine.com/enginespecs.php?recordID=58Yamaha F40/30 Jet 4 Stroke: ready to install–227 lbs
http://www.yamahaoutboards.com/outboards/Jet-Drive/specificationsYamaha F60/40 Jet 4 Stroke (have to custom order as a tiller handle–a bit heavy to steer)–weight 259 lbs

Travis, as I understand it your intake sits several inches below the hull. I have been lead to believe that the leading edge of the intake should be level with the hull with the heal being below that. Is there some cavitation problem with the hull, or did I get the depth of your intake wrong. Thanks
