    The F70 is a great motor, but for that rig the 90 is the only way to go. The displacement between these two motors is where the big difference lies. I run a 20' tiller with a 90 (Merc 4-stroke command thrust) and it is perfect. I would not worry about the extra weight with that big and wide of a hull.

    I run a Suzuki df115 tiller on mine and its plenty of power and I haul heavy loads.

    What??? ALL the reviews I've read on the Yamaha f70 have been very good, and I own one and confirm it is great for it's hp/weight ratio, performance, and durability. There's several others on this board that have bought it as well and like it.

    Thank you! Tumble weeds and cord grass is the winning combo on hard sided blinds. it hides nice

    lastflight said it correctly the 2072 needs more than the f70 the bad press it got was several years ago when they were installed on heavy boats and overloaded they are a h.o. motor with the 4 valve set up not great torque and with a 2072 your going to be running heavy lots of times.

    ... interesting, I guess my 26' 3500 lb boat is not "heavy"???

    I'm sure the 90 would be great too. Don't think you can go wrong with either.

    Buddy of mine had a 2072 SeaArk starting 2001. Ran a Mercury 150 EFI on it and never lacked for power. Unfortunately, he lost the rig in a garage fire 7 yrs ago. Miss hunting out of the Queen Mary. Had many a good 5 man hunts out of it!!!

    Interesting, I didn't know they made one with a tiller at that HP. Learn something new every day.
