Not sure on weight of the 150 vs 200, or if it's Truly the HP that matters most when rating the boat.  I "think" it's the HP myself and not the weight of the motor as much - all engines weigh differently.  You don't want to be pushing your transom past you as you jump up on plane.  [wink]  That extra xxx lbs of the motor weight difference isn't the key, since you could add an extra bank of batteries back there, even with the 200.

Probably a Dealer question to see if they can be "synchronized" a bit where you're not pulling it out so often.  Can we reach a happy compromise here?  

No marine growth where you are to justify some bottom maintenance when pulling out?  That'd be sweet, but around here a boat bottom looks like a kelp bed in 6 months or so.

Rooting for ya!  [smile]

E-tec 15 H.O. 177 lbs.

Tohatsu 9.9 efi 118 lbs



The cost difference is significant too lol. I really love only having to put the boat on a trailer once every three years to take it for maintenance. So I find the 15 HO very attractive in that regard, but the 15 HO’s three year service would be due on different years than my 150E-etc, so I’d still end up bringing the boat up two out of every three years I guess, at least during the warranty period.


Hi,
Just a couple of additional things you may not have considered re replacing your E-TEC 15HO with the Tohatsu MFS9.9. Which for your application, apart from the weight difference, may not be a consideration.
The (2 stroke)15HO develops near twice the amount of power as the (4 stroke) Tohatsu 9.9 as the 15HO being a two stroke has one power stroke per rotation of crankshaft, whereas the Tohatsu being a 4 stroke has one power stroke per two rotations of the crankshaft.
Also two strokes develop more torque right from the get go where you need it the most as opposed to 4 strokes but don’t just take my word for it. Here’s a real world article “2 stroke V 4 stroke” that sums up the advantages and disadvantages very neatly.
https://www.ryanmoodyfishing.com/two-stroke-vs-four-stroke/
Another concern is the service requirements of the 4 stroke Tohatsu MFS9.9 which requires an oil change every 6 months / 100 hours and oil filter every 12 months / 200 hours as opposed to No Dealer Scheduled Service required with E-TEC for 3 years / 300 hours.
Also the 4 stroke Tohatsu MFS9.9 has a break in period which takes 10 hours to complete.
I admit that having owned an E-TEC 30 remote steer and now an E-TEC 25 Tiller I’m biased towards the E-TEC and I’ve nothing against he Tohatsu brand. To me this is all about the pros and cons of 2 stroke V 4 stroke and you’ll be that one that decides which is best for your application. I’m just trying to add “knowledge” that may help you make a better informed decision.
Also the Tohatsu Owners Manual / Operators Guide can be downloaded from this link. Lots of useful information there.

I think you are correct, I don’t think there is a weight difference between the 150 & 200. Fingers crossed, but no growth so far in 4 seasons, the rack and launch does an amazing job keeping it clean.

Thanks so much for your help, I’ll be sure to update with my decision & results.

Thank you for the information. Everything you mentioned is part of the reason I lean towards the Etec 15HO. Especially the maintenance, I’d rather not deal with it. I also really love the idea of the +-50rpm button, no need for a separate trolling controller. Appreciate the links. Going to read them now

I have used Lockemans and they are truly the pros on the Detroit River.  I have a 22' Sportcraft WA pushed with a 150 HP G1 (E150DPXSUC) and a 36 VDC Minn Kota Ultama on the nose.  1400 hrs on the G1 using XD100 oil.  I have both the minn kota chargers (3 battery 36VDC) installed on the boat (AC and DC)  I also have the accessory charge lead on the G1. I have had long discussions with the design engineers @ Minn Kota about the function of the DC to DC charge circuit.  Also, I am using 3 group 31 deep cycle batteries to run the trolling motor.

Some comments:  Do not try to charge the batteries while using them to run the trolling motor.  The motor control electronics are very sensitive and like smooth DC power supplies.  I have been charging the trolling batteries via the G1 and the 25 amp output throttles the amount the Minn Kota DC charger can provide.  The charge rate is very low (slow), so I would need to make a 40 mile run to see an improvement of the 36 VDC battery SOC.  I wrote a missive about this after I had hooked it previously on this web site.

Low speed trolling, I like the bow first steering when it is windy as I have a sail area that will cross you up sometimes.  If trolling for salmon, run the G1 at troll speed and use the front mount trolling motor to assist and steer.  Works like a champ, no more driving the boat in difficult conditions.  I have not used a kicker since this installation.  

Also note - the whole package is heavy (bow heavy?) and I use an 11" pitch inertia wheel on the G1.  Keeping the RPM's up when running is the solution to long engine life.  Thinking of fishing in MI, how many days can you go 35MPH in cold fresh water?

I will be running my equipment this way until I am in a box......

There is some major wrong information in the reply's to this post!!!!

The 15HO produces a max amp output of 56amps and it uses 15amps that are dedicated to run the motor! SO there for it has a max output of 41amps for charging at full RPM!  The motor produces 7amps at idle and 15amps at 1500rpm!!!  

I run a MinnKota DC Charger and it in conjunction with my 15HO is amazing!  I run a 4 battery 24v trolling motor setup with 4-31s batteries in series/Parallel. I added a battery meter on the bow that allows me to monitor the reserve usage of my trolling motor batteries.

For typical trolling for Salmon or Walleye here on Lake Ontario or Lake Erie (15HO used for purpulsion and my MotorGuide Xi5 steering). I will run at 2-3mph in my 19' Lund and I also installed a cheater tach on my dash for the kicker.  RPM at those speeds are 1750-2250rpm which means I am pumping aprox 17+ amps minimum to my bow mount batteries every moment the kicker is running!

In a typical day on the water (10hours) I use the combo the whole time and at the end of the day I am at 90% left in my reserve. (so for a normal 2 battery setup with 31s batteries you would be at aprox 80%!!!)

Last summer we went up north to the lodge we have been going to for 30+ years and has no access to shore power. In 2017 (first year with the boat) I made it 1 day on my batteries trolling shore line with the big motor pushing and the xi5 steering and then I had to break out the noisy genset to charge at night.    Last summer with the new setup we did the same trolling and at the end of the 6 days of fishing and not touching the generator I was still above 30% and my red light on the Xi5 never even turned on!

All in all...The 15HO is an amazing motor in every way except the extra weight but the AMP's are amazing and so is the touch RPM control! Fuel efficiency is amazing and last year I ran it for 120hrs and when I filled with XD100 it took just under half a litre!!! simply amazing!!!!

Any questions send me a message or better yet call or text me at 519-778-5441 as I don't get on this page a whole lot.

Good luck...Ryan
