ILLOWA Marine -

Home of the Phowler Boat Company

and the

NEW BIG FOOT Phowler Store

Winter is finally here at Illowa Marine and Phowler Boats and folks are finishing up another season on the water in Phowler custom hunting rigs, but it is not  to early to be planning for a new rig!  We can still get rigs ready for late winter or spring delivery. If you waited to long to order last year, don't wait this year, we are already 10 weeks out for new builds and it not even January 1st yet!   Phowler build times are right at 10-12 weeks right now, so there is still time to order your new rig and have it in time ice out up north.

Lots of orders also mean lots of new trade-in rigs - check out our Pre-owned Specials page for fresh trades.


      Beginning January 1, 2015 all new Pro-Drives 36 hp motors will come standard with Briggs and Strattons new EFI engine.  Motors will go up about $500, but will have EFI standard.

More Power for the 23hp Vanguard!!!!!!

Upgrades for Copperhead Briggs 23hp surface drives!!!!  We spend this past spring and summer testing various reworked heads, carbs, intakes and mufflers for the 23 hp Briggs Vanguard engines and will be introducing a new performance kit that will take the 23 to near 32 hp!!!  Call for details.


We spent four weeks this past summer remodeling our showroom in order to add new products our customers have been asking for. We are now a BIG FOOT Factory Outlet - we stock Big Foot field and Goose floaters at all times.  Our prices are below the allowed advertised price - lets put it this way, we are right next to the factory and we have price shopped, you will not get the USA made full size Big Foot Goose decoys cheaper anywhere (if you want quantities over 4 dozen of any one style, call ahead and we will have them hear when you come in). Big Foots are available for in store pickup or shipped direct to you.

We have also stocked our showroom with all the stuff you need to complete your hunting rig including seven different colors of raffia grass, Mr. Heaters and all the hoses and hard to find parts to build a heater system, custom heater boxes, push poles, Camo Flex Limbs, camo fabric, etc.  We stock the stuff you use.


With our increased orders we remind potential customers to call early and book your orders early for set delivery.  We have adding new welding and support positions but we will not "speed things up" at the expense of quality, so book your orders soon.  

We are currently stocking PD motors, Copperhead Motors and Suzuki Motors - Including the new Copperhead with clutch option and will try to keep motors in stock through the hunting season.



Here at Illowa Marine we are fully stocked with used trade in rigs that need to go to make room for fall trades.  Check out some of the great deals on our Pre-Owned Page.

Still thinking about a new Rig for fall, don't wait, we are stacked up with new custom boat/blind and motor orders, but we still can get you into a new rig before the regular season.  Call today and let us help you design you new rig!

We believe sportsmen expect a lot from the equipment they invest in.

At Illowa Marine, we take the time to listen, answer your questions, and design a sportsman package specific to your unique needs and expectations. We don’t sell low cost products or product lines with high dealer margins. Instead, we pledge to find, test, and offer only the best products that meet the needs of you: the sportsman. 

In today’s fast-paced markets, we still believe that the customer always comes first; and it’s that personalized attention that continues to set us apart. We stock models not readily accessible from other dealers and we continually look for new product lines that keep our sportsmen on the cutting edge. Ninety percent of our customers custom order boats specific to their needs, and almost eighty percent of our sales come from customer referrals. 

We offer product lines that are time-tested and innovative to the hunting, fishing, and marine markets. When we offer you suggestions on boat and motor options, we offer our suggestions from first hand experience: 1) We have run the product, 2) We know what the product will do or won't do, 3) We won’t sell you a product that does not meet your specific needs.

At Illowa Marine, we are committed to the following:

  1. Offering you the best products we can find
  2. Making ourselves the most informed and knowledgeable dealers we can be
  3. Informing you about all your options 
  4. Backing everything we sell with exceptional service and support 

We don’t expect your business; we expect we will earn it!
