    Hello everyone, I'm new to this forum, and wanted to get some input. I am leaning towards a seaark 1872 mv with a tiller steer 70 hp Suzuki. The max hp in tiller for this model is 80, but Suzuki doesn't make one, they jump up to 90. I am concerned about performance issues, and am not ruling out the 2072 with the 90 tiller. I originally was looking at the 1860, but after seeing the 72 models, I liked the idea of 28 inch sides, and the heavier gauge aluminum. I plan on hunting the Ohio river, along with Ky lake. Any opinions on performance or other considerations would be greatly appreciated. Thx

    although my 2072 seaark duckhawk is side console a 90 etech is plenty of motor for that hull. fully loaded w boat blind , decoys , dog and 4 people it will still run in mid 30,s. just 2 head and fishing gear will hit about 42. Is the 90 & 70 Suzuki made on the same block? On the etec they are , so weight wise same load on transom. I would think the 70 would push boat fine but you,ll never go wrong maxing out horsepower rateing on a hull.

    Thanks for the info. I think I'm going with the 2072. We have a small runabout to take the kids out, but my wife made a great suggestion. Get rid of the runabout, make the seaark a console, and increase the hp if need be. That way we can use it all year long, take the kids tubing etc, and will still have my duck boat. I liked the idea of the tiller, but with side console there should still be plenty of room. It's kind of a win, win. Gotta love that woman.

    I have a 115 merc on my 1872 and with 3 guys and an empty bowfishing load we can run 40 mph. It will run high 30s with 3 guys a hard sided blind and a full load of hunting gear. I wouldn't go any smaller than a 115.

    In order to stay tiller steer, 90 hp is the max I can go. Going console, I can increase it much higher.

    That hull will throw a little spray over the side with wind hits underway just right. To advoid this I moved my side console ahead just far enough to allow a pedestal receptacle to be installed thru floor. Makes for a dryer ride in rough , windblown water. My duckhawk hull has walk thru back seat boxes set up for running a tiller motor. I think the MV full seat hull comes forward about same distance as those bxs do but not positive. My 90 pulls kids & adults flying on tubes or skis.

    If you go with a 70, you'll save 85 lbs going with a Yammie over a Suzie ......

    X2 on the Yamaha. I run an F70 on an 1860 seaark center console. Easily runs upper 30's with gear well placed for weight distribution. My dad purchased a Suzuki 70 hp the same year. The power head on the Suzuki 70 is the same as their 90 hp. Yamaha saved a ton of weight by tuning the 60 hp power head up to the 70. Had it 3+ years now with absolutely no troubles. Has started quickly no matter the temperature, and runs very quiet.

    I would run a 90 tiller on the 1872 and not worry about it. I have a 115hp tiller on an 1860 that is rated for a 70hp. No problems here. Not too many people beating me to the hole though! 5.jpg
