ELECTRIC TROLLING MOTORS
my 9.9 evinrude is pulling my tramsem away from my older aluminum grumman. want to sell this and go to an electric troller. looking at the bigger sites but can't seem to find an answer to my question. how big of a motor do I need to propel an 18 ft. aluminum with 2 or 3 people in it. any advice would be greatly appreciated. anyone looking for a great running 9.9 kicker?

Well i bet 30lbs of thrust would move you not fast but move you. The best an electric will do is maybe 4-5 mph top, thats 101 lbs thrust. Best bet for price and preformance go 24 volt around 70 - 80 lbs thrust. Unless you go edrive from minn kota 48 volt system but them you might as well buy and outboard. You will never match the thrust of you 9.9 in electric.

Pike, we frequently use a 15 ft older aluminum with 2 people and gear I would put it at about 800 lbs total. (tackle bags, 100lb 9.9 motor, gas, batteries... adds up very quick) We run an 80lb thrust variable speed 24volt trolling motor with it and are very happy with the performance. It will push at about 3.5 to 4.5 mph depending on wind and current at full speed but that will drain batteries quicker than you would like. If you are using it for general maneuvering and slow trolling it will go for 7 to 8 hrs...
The heavier lb thrust you get with the 24 volt systems are great, there is a trade off with the weight and upkeep of a second battery but for our purposes it is worth it. If it is going to be your primary source of power on the water go with as large of one as you can afford with good batteries...
ps... we always have oars in our boat, just in case...lol

Depends on what your budget is. I have an 1800 Lund Fisherman. Big and heavy enough to fish Erie. I have a Terrova 80lb. auto pilot w/universal sonar, 24v. Pulls the boat with no problems. If your budget is lower, you could go with a 12v in 55lbs. Should be OK with that also. To get longer run time, you may want to get 2 batteries and parallel connect the batteries. That way you will still have the 12v but you will double the RC of the batteries which will act like you're running a 24v system. Bottom line is get the biggest one you can afford and get the longest shaft (60") too. Better to have more power than you need because on those real windy days, you'll wish you had it.

I have a 16.5 aluminum and usually fish atleast 3 people out of it. I would recomend atleast a 55 lbs thrust motor. I know mine does a good job but like eyegore said on those windy days you will always wish you had more.

I have a 12v 55lb thrust motorguide on my tracker tx170 which is like 16'7" or something. Completely loaded down with gear (10-16 rods, 5 big bags of plastics, big box of cranks, spinner baits, 2 anchors, drift sock, extra prop, cooler with ice food an drink etc....) and 2 people it pulls the boat at 4.5mph GPS indicated with an open water 2 blade prop and maxed out.

I'd suggest that you keep your 9.9 and repair /fix /support the transom. If a 9.9 is pulling the transom apart on an 18' boat ..., you have more problems then deciding on which trolling motor to get...

do any of you have a digital trolling motor? they claim you get 3 times the battery life using them.

Someone told me that one horsepower is equal to 14 pounds of thrust. If that is true, a 9.9hp motor would be similar to a 140lb thrust troller....
An 80lb thrust motor would be similar to a 5.8hp motor.
Take the info with a grain of salt, I have not verified the info.

Hiclass, from my searching they roughly claim 70lbs of thrust is about a 1 horse power. Minn kotas web sight will not explain it out, they are measureing two different things with those ratings.
