Trolling Motor Upgrade 50 lb to 70 lb


Question

Posted

I'm looking to upgrade my early 2000's Minnkota Powerdrive 50 lb trolling motor and I'm finding that based on my boat length and weight a Power Drive v2 70 lb seems to be the best bet according to what I've read.  My question is will I notice a noticeable amount of added thrust between an older 50 lb motor and a newer 70 lb motor? 

Right now with my old 50 lb motor I have a hard time getting to 2.0 mph on a calm day with just me and a small amount of gear in the boat (Lund Explorer SS 1650, 75 hp Mercury 2 stroke) and I'd like to be able to easily get up closer to 3 mph as a lot of the tactics for walleyes these days talk about trolling cranks up in that speed over weeds.  Also I'd like better control on windy days then I get now.  Do you think a new Power Drive v2 70 lb would get me up in that speed range with my setup?  Would a 80 lb Terrova be a big jump over a 70lb Power Drive v2? I don't see a big difference between Terrova and Power Drive V2 other than the 112 lb option...

I have a 80 pound terrova on an older 1775 pro-v with 140 suzuki and in might get to 2.5.  Above that I can troll with the big motor (or a kicker)

 As Del said you'll see a little improvement and your run time longer.    At 3 mph your going to go through the batteries reserve fast.  A kicker to get you up to speed and your bow mount on auto pilot to keep you on coarse IMO is the way to go and on windy days the only way to go.

I don't think you will get 3mph.  I checked mine last night and 2.5-2.6 was it at "10".

Yeah I'd say getting to the low 2s consistently and at least having control in the breeze a realistic goal.  I was out Friday and could just barely get it to 2 going down wind (a light breeze), but mostly in the 1.6-1.8 range max.  I think my brother has a 112 lb unit on his 17' crestliner and can get it up to near 3, but I'm not sure I want the added batteries and cost in my slightly smaller boat.

A 70 or 80 pound 24 volt unit should get your boat to 2.5 not wind aided.

I have an 1850 Lund Impact with a 150 hp Honda 4 stroke on it. An 80# thrust Terrova, 24 volt will easily get me to 3 mph at a setting of 5. Batteries will last all morning at that setting.

If you want more speed and more control go with the 80# thrust motor. The Terrova also has a lot of great features that you will like and use.

Not sure why you can't get 3 mph out of your main? I troll deep diving raps all the time at 2.88 to 3mph on my main 75 hp 2 stroke Merc on a 17.5 Starcraft.

Do you tilt your main motor to reduce drag ?

I have done that at times. It depends on how much wind I am bucking and if I need more or less speed. Always make sure you have a good water stream coming out of the motor to keep it cooling.

Wow, Cliff.  Maybe my 6 year old batteries really are getting feeble.

      I wonder like divers, if we let them decompress every 10' for 1/2hr. If that would help?  🤔  It would slow the bite down a bit!  🤭

      That was a better study compared to last winter when they setup the vertical tube nets and tried to release exhausted fish from being studied and expected them to be able to swim straight down a 3' hoop net.     That lake's crappie population from this latest video was pretty deep at 40-50', and no doubt from those depths that is barotrauma for most.  That is deeper than most crappie holes but certainly how some are. However from helping give fish a good release from the 35' and less range and tracking them with live sonar most of them swim at a shallow angle back to the depths and I watch them rejoin the school and be active.  Uncut Angling's video helped counter some of the initial narrow findings.

      If you fished with me more often, you'd never have to make this statement...   38" of ice - love it. I'm really going to have to dig around for my auger extension. I don't think that I've needed it in over a decade.   Too bad nobody has a locomotive chugging across the ice to do some logging, like the good old days.

      On the South Shore...  Ice fishing remains strong across the south shore of Lake of the Woods out on Big Traverse Bay.  Resorts and outfitters on some parts of the lake have ice roads extending over 16 miles staying on nice schools of walleyes and saugers.  Many fish houses are over deep mud.  Some are on structure.  It is always fishing of course, but overall, February has been very productive for most anglers.   Extensions are being used on ice augers as the ice continues to thicken.  The thick ice this year will be good for the extended ice fishing season Lake of the Woods enjoys with fish houses out through March 31st, walleyes and saugers open through April 14th and a pike season that never closes. Most fishing activity is taking place in 26-32 feet of water.  Anglers are finding a healthy mix of walleyes and saugers, with a good number of jumbo perch in the mix this year.  Some big eelpout are also showing up.  Anglers are reporting plenty of fish for fresh fish frys and usually extra fish to bring home.   The one-two punch of a jigging line and deadstick is the way to go.  On the jigging line, jigging spoons with rattles tipped with a minnow head have been consistent.  Lipless crankbaits and jigging rap style lures also doing well.     Lures with a light have been working well in the stained water.  Please remember, in MN, lures with a light or water activated light can be used as long as the battery is mercury free and the hook is attached directly to the lure and not as a dropper line.     On the deadstick, a plain hook or a small jig with a live minnow 6 inches to a foot off of the bottom.    Some days, mornings are better, other days, it's the afternoons.  There is no distinct pattern, they could come through at any time. On the Rainy River...  The start of the day and end of the day have been best for those targeting walleyes on the river. A jig and minnow or a jigging spoon tipped with a minnow head is also producing some fish. Some big sturgeon being iced by ice anglers targeting them.  It is a catch-and-release sturgeon season currently.   Although ice conditions on the river are good, they can vary significantly due to the current, so anglers should always consult local resorts or outfitters for the most up-to-date safety information and fishing advice. Up at the NW Angle...  Ice fishing has been strong in the islands area of Lake of the Woods. Resorts continue to move their fish houses around, staying on the best schools of walleyes.     Anglers are catching a nice mix of walleyes, saugers, and jumbo perch with an occasional pike or tullibee as well.     Big crappies are still being caught just over the border.  Fish houses are available, check with a NW Angle resort for info on crappie fishing.   Lake of the Woods enjoys an extended ice fishing season with fish houses on the ice through March 31st and walleye and sauger seasons open through April 14th. Perch, crappie, and pike seasons remain open year-round.

      Maybe you should put rattle wheels down, if your going to sleep for 6hrs! 🤭 😆

      Monday was my worst day of winter fishing on Vermilion in the last 4 years.  Caught only one 14" walleye in nearly 8 hours of fishing.  Missed two other bites and was marking very few fish.  Maybe the fish were taking Monday off after a big weekend.   No more water came up on the ice under my house.  Think it was because I haven't banked snow around it for a couple of weeks so the bare ice around the house is getting very thick.  I measured 38" of ice under my house and the Ion barely made it through even with the extension installed.  Needless to say I banked around the house this time.  Another lesson I learned today is don't drill holes if ice is frozen on your blades.  I did that on one hole and it didn't center properly and drilled at an angle on the edge of the opening.  Hope I can correct the location and angle on my next trip up.   Not much change in the surface lake surface conditions.  The drifts may be a little higher and are definitely harder.  There are still a few bare ice spots on the lake.  Very little activity on the lake today.  There are about 3 dozen houses from McKinley Park out to Birch Island.  Another person pulled there house off today, and I am sure many more will pull theirs off this coming weekend.  Only 13 days left of walleye season.
