Not sure if this is the proper repository.
Among my too many project designs, is a plan to build a canal boat for the vast system here. Simply it will be a flat bottomed poling skiff. Narrow beam near 16' long.
The engine will be a Honda GXV50 or clone, attached to a modified outboard, to turn it into a surface piercing prop design. Fun.
The boat will have a tiny center console...which brings on a dilemma. I do not fancy having a super long throttle cable. (9') What I am trying to find is an Arduino based throttle kit. Not having much luck. Many build their own. I just want the kit.
It would not be fancy, but requires the following at a minimum: - Helm throttle, with TPS input (not hard to find)
- Controller ECM, Arduino or ??
- Throttle plate servo with TPS feedback back to ECM (feedback is optional)
- Wiring for the above. (4 wire)
The car stuff is all too bulky, except the throttle plate servos, but they are model specific frames.
Must be some of you young guns or buns that have controller geek sense. What do you know?

A boat of that historic a design may have a serious allergy to computer stuff (the devils invention, we know). Somewhere cable by the foot is sold.

You are correct. It is somewhat of a classic that morphed over 150 years. The 1800's saw heavy planked sides and bottoms. Today they are plywood and frames. Mine will be similar, but hardwood and a nice stem that stands proud over the rails. Thai style. The plan says 96 pounds. Mine will be heavier some.
The confuzer parts will be hiding...I want to see wood.

im not sure if they make strong enough servos but, have you thought about R/C boat parts? the remote can be small and hidden easily. the servos and controllers should be somewhat water resistant. they can work on a 6v-12v+ power source. the motor you mentioned has a charging circuit for the electric start battery, I believe. I know they make bigger R/C boats that haul ass. so their electrics should be pretty stout. im interested in seeing what you can come up with. youre a knowledgeable resourceful guy. im sure its gonna be cool and probably fast

Thanks harley...am finding parts. Some companies making kicker motor throttles, but they cost more than my engine and drive unit. Last night, I found a small servo spec that is being used for just this app.
This boat will be smooooth and likely too fast for hard cornering, even with a 2.2hp motor. But the future holds some race boat fun with different hulls, bigger power. Just wish I could plug-n-play for less than $500.
The material will cost under $200, the engine + outdrive under $175 before my mods...call it $300 with the surface drive installed. Labor is me. Worthless. Or worth less.
So my e-controller is half the total cost...and I must hide it's ugly interface.

This was a great suggestion! I found servos that are small and can handle from 10kg (throttle) up to 60kg (steering) in a waterproof housing that is only 5.5cm. (2 inches+). Now we are in the running! I think they were $12 to 26 from everyone's fave country. Some include billet aluminum control arms/eccentrics and more. (Some are ABS)
This was from a search for RC/Robot steering controls an AliExpress. Thanks Harley!
For education...60kg is 132 US pounds. More than enough. The 15kg version is overkill for the throttle...so quicker response?

I'm glad it was a relevant suggestion. your project sound fun. if you go the rc route, you could make the controls removable, and be able to have your boat pic you up at your dock or drop you off and you can control it to its parking spot from your door. I know rc airplanes controllers can reach far. I think over a mile. that's wide open air space though. also, if controller is removable, if you take it with you, no one can control it but you. that's a theft deterrent device!! lol. cant wait to see it done. I know it'll be fast and cool. as to the over kill on strength. I'm not sure on the faster response but, I know in other situations that over kill will add to the servo's lifespan and reliability. if you're maxing its weight limit all the time. I'm sure it wouldn't last as long a servo that only sees a 1/4 of its limits. if you make this work, I'm gonna have to adapt a similar setup in an old flat bottom V drive!! make me a life size remote control speed boat.. lol

Awesome harley! This will not be "remote"...as in sippin' Kool-Aid and drivin' from shore. It will be control of throttle and maybe steering from amidships. A sixteen footer. However, wires are simple and small and lightweight. PLus, I can hide them under some fancy wood work. Now...a game controller with a steering wheel that isn't cheesy/plastic. The throttle is easy. Think lawn mower done right...wood! Not this, but clean and simple:

ThaiGyro, hi. really great project. I don't know if this guy might be of any help but for FPV and I think probably RC in general he knows his stuff. Maybe you could contact him for R&D , parts search etc . .

Thank you jloi! Sent him a PM...I am trying to make this simple. Mimic the analog systems with no frills.

For the steering wheel with remote, there are some serious Forza and Microsoft Flight rigs out there. No plastic cheesy bits.
Might take a look at Pinterest for ideas and then bore down into the links for more details.
Instructables might be another source of info.
