Got my boat back today, repowered with a 90HP Evinrude E-Tec. Here are the results of the "get acquainted" ride of about an hour.
Boat: 1997 Smoker 161 ProMag, 16.5-foot aluminum v-hull walleye boat, loaded full of fuel, 3 batteries, PinPoint bow mount, usual "stuff", and driver. Gross weight, probably around 1350-1400 pounds estimate.
Old motor: 1996 Johnson 90HP V4
New motor: 2005 Evinrude 90HP I3 E-Tec
First impression: "Are you sure that's a 90HP? It sure looks awful small." Interestingly it weighs 9-pounds MORE than the old V4 (310# vs 301#). Nice streamlined package. Lower unit looks beefier than the old V4, but otherwise seems much more compact.
Second impression: (Turned the key for just a second.) "Is this thing running? Yep, the tach shows 650 RPMs." At idle the thing is dead quiet. All you here is a slight sound of mechnical "hum", and the splash of the cooling water 'tell-tale'.
Ease away from the dock --- yes, it must be running because we're moving. Still whisper quiet at around 1200 RPMs.
OK, let's cruise.... throttled up to around 3500 RPMs. The boat pops up on plane smoothly/effortlessly and trims out solidly on a moderate chop. "C'mon, are you sure this isn't a four-stroke? Where's the roar?" The sound level is incredibly subdued, a nice solid low pitch throb, but it seems so far away!
OK, lets HIT IT! (Yes, no break-in recommended!).
On the old motor (even when it was new) you scratched and clawed for speed, topping out around 37.5MPH after about 4-5 minutes on a flat-water downwind run, constantly tweaking the trim to avoid porpoising.
As the old guys says on TV "Everyone Loves Raymond" if fond of exclaiming ---- "HOLY dump" ---- The E-Tec ramped smoothly from 3500 to 5500 RPMs in seconds, and the GPS clocked at 45 MPH. "But where's that famous Evinrude howl?" Even wound up to 5500+ RPM, the engine is just a solid "thrum" at a db level that you can easily hold a conversation over.
Acceleration from any speed is smooth and strong without even a hint of hesitation or stumble. Prop is a 13-7/8 X 19P Viper stainless steel. It's amazingly insensitive to over trim, holding the bow nicely up until you overtrim to blowout.
All the above on a modestly windy lake with a confused/irregular chop. I can hardly wait for a nice flat lake to put it through its paces.
Suddenly I'm glad I couldn't afford the four-stroke I wanted!
I just figured that it is easy enough to just get a 3 bank so when the boat is not in use I can keep all 3 batteries charged. I have not bough a charger yet, maybe I will give it some more thought.
Edit: After thinking this over, with the size, weight, and heat output of the charger (as well as the cost) I think it makes sense to just
buy a 2 bank charger, I have a smaller charger i can use on the starting battery when the boat is sitting at home. Forgive me, for i am a retired engineer and I have to obsess over everything...
Congrats on the motor! I think you’ll like it.
I can’t say much on the charger location but I’ve seen them under the lid in back compartments and under center rod lockers. 160 degrees is more than I expected to hear.
Curious why you’re opting for a 3 bank charger with a 24V trolling motor. Unless you don’t feel you be running you big motor enough to keep that battery up as well?
I did buy an Minnkota Ulterra, thanks for the recommendations. I had a bunch of Cabela"s bucks saved up, which helped. Now i need to
get an onboard battery charger. Where do you guys mount these things in your boat? The manufacturer I am looking at {Noco genius)
says tht their 3-bank charger will run at 160 degrees, seems like a lot of heat in an enclosed compartment? Thanks for any input on this.
Wasn't terrible at a state park beach. Antelope island maybe. I wouldn't recommend it as a beach destination tho. Figured I was there, I'm getting in it.
