Can I make my own throttle control w/ a potentiometer

Can I make my own throttle control w/ a potentiometer


I’m in the process of adding my new 2016 Honda 9.9HP kicker engine to my homemade dive platform (still under design and construction).


I want to electricalley control the throttle from inside pilot house.


Can I obtain the servo http://www.iboats.com/TrollMaster-Servo-Kit-TrollMaster/dm/view_id.887115?cm_mmc={cmids}


Example I won’t spend a dime at this iboat site.


Then use a potentiometer to control it like are the controllers work off resistanse correct?


Anyone here own a https://www.amazon.com/CONTROLLKING...0032N03P4/ref=cm_cr_arp_d_product_top?ie=UTF8

That can mearsure the resistance values at closed throttle then at WOT.


Thanks TB

 

Not just with a potentiometer. You will need a regulated voltage supply. Otherwise, the signal will vary with the battery voltage and be erratic.

 

There are some old posts here I wrote about DIY throttle and gearshift control.
Now, in 2017, instead of making a circuit board, I would make my life easier and use an Arduino microcomputer and write the software for it.

 

something like this?

I understand a little about controls writing a simplistic program for 1% increment of up/down throttle couldn't be difficult for a accomplished programer however assemble language was my worst subject in college.

mite be easier to purchase a con troll king. I'm not seeing used units so people must like them and keep them.

I have not looked much or even read the manual on the Honda 9.9 will it have a cruise control like can I set throttle say 20% and lock it to the 20%?

There are several options out there from just a limited throttle control to full auto pilot that will bolt right onto the motor. While it may cost a little more, it will come with all the brackets, cables and other items and will be a simple installation.

 

I'm not quite ready to invest a small forture in electronics however I do plan a real sys. MFD/depth sounder/GPS module/external GPS antennaradar/auto pilot I'm researching this stuff.

I actualley just got my ray marine GPS/depth finder working now if I could only keep the RM transducer in the horizontale position it constantely wants to invert to vertical position.

topic subject?

You should read the manual and then ask questions. Boats don't have cruise control like cars. The throttles are set at either a fixed RPM or a fixed throttle setting; at least with a setup like yours. It is possible to link a GPS to the engine to maintain a fixed speed. However, it is not something you can cobble together. It will require CAN and a computer controlled engine.

 

yes I should read the manual

if I remember correctly my 1997 Evinrude 25hp tiller had a cruise control.

at the end of the tiller there's a nob that can be tightened down at a desired RPM.

I never used it because I always had my hand on throttle.

now w/ the Honda I won't have my hand on throttle. Not sure if Honda has this nob?

doe's the 2016 honda have a computer?
here's some specs on it

Why are you trying to reinvent the wheel? Just get a remote outboard control kit and mount it. Get a sh one if your purse is tight.

 

do you understand what a tiller is? if I wanted second remote outboard control I would have purchased a none tiller. I have second boat 15' deep V aluminum this 9.9 will power.

Also the kicker will be on portside to not interfer w/ transducers.

If all you want is a friction tensioner for the throttle then it's very simple even if it doesn't have one stock, which it probably does.

A piece of inner tube cut to the correct size can be slipped over the grip with part of it on the tiller handle.

This will hold the throttle grip on the correct position.

 

Yes I know what a tiller is, but I have decided it's not worth it to prolong this conversation. Good luck with whatever you are trying to do.
