A Buddy of mine is thinking of getting a SeaArk 1860. There are a few lakes in our area with a 25hp. limit, so he was wondering if a 25 would bring it up on plane? Has anybody out there tried one? Thanks, Rusty

A 25hp would probably bring it up on plane, probably being the key word. But it would be seriously underpowered. I think if I had a 25hp limit, i'd stick to a 16-17'er or smaller.

dad had 16 lowe with 52 inch bottom with a 30 HP mariner would plan fine and run around 20 miles an hour with 2 guys , but not 4 people and a shad tank full of water.

i honestly think you will be just fine , unless you plan on getting 10 miles or more from the boat ramp never know what the wind or bad weather could come up.

I have an 18 fiberglass foot bass boat that I hope to start as a catfish boat project. I'm going to gut it and rig it up catfish style. It is some wider, and 2 feet longer than my J 16 Carolina Skiff. I am hoping a 25 or 30 will push it. It doesn't seem like an excessively heavy boat, and will be lighter still with the console and controls removed... Do let me know how the 25 works out on the boat mentioned.

I guess if he is limited to a 25 on the lakes he fishes most, he will be pretty much relegated to the 25. If these lakes have these restrictions, power should not be a key issue. My main concern when planning such a project is FUEL CONSUMPTION. Under powering can be very inefficient. You must find a balance like Bubbakat said.

Did your buddy ever get the boat and 25 hooked up? If it's a standard model 1860. I think a 2-stroke would be ok on it. And would like to hear how it worked out if it did?
I posted below that I had the 25 4-stroke on the 1756 War-Eagle. Now with 2 people and fishing gear. It would run up river with the current around 24 MPH an down river with a 3 MPH current at 28 to 30 and that Was bu GPS. It did good on that boat as long as you did not load it up. But it also drank gas. It would burn more on the same trip, Then the 20ft war-eagle when I had the 85 HP motor on it. And when I put the new 140 Suzuki on the 20ft war eagle. It would go 24 miles on less gas then the 1754 would go on 4 gallons and 16 miles and burn over a gallon more doing it then the big motor also.
Hope he worked it out. and you can post the results.

A 25 hp on an heavy SeaArk 1860 is gonna be a slug. Getting it up on plane wont be hard but it will drink fuel staying there. Your gonna need a jackplate, hydrofoil, and probably have to reprop it which will require a tach. This is going to add a few $ to the cost of this rig. You may want to think about a 16' boat if you are going to stick with a 25 hp motor.
I've got a Lowe 1652 fully rigged, with deck and floors, and with a full livewell, 2 people, cooler, and gear, my Johnson 40 2 stroke with hydofoil will run 28 mph, with the livewell empty it will run 31 mph.

I dont think he would need a jackplate,, he's net going to be runung any type of surfusing prop or cleaver that requier the blade tips to get air, jackplates are also used for getting the LU up and redusing the drag from the LU. and adding a little more leverage to lift the bow

I do gree on a small pitch prop,,,,8-9p is where I'd start off

I agree. Also, a riveted jon is quite a bit lighter than a comparable welded jon.

A jackplate will also set the outboard back (6" to 10", depending on manufacturer) which will change how the boat handles and planes as well as the speed at which it planes.

My buddy ended up getting a 2 stroke 40 hp. Nissan. It seems to be enough motor for his needs, but it is still in the breakin period. Thanks for ALL the input guys! Frog Legs

I know he will like it better with the 40 then he would have with the 25. If I could have bought the 15 degree hull with a Tiller motor. I would have maxed it out with a 75 or 90. But was going to have to buy a console boat and then strip it down.
