DIY not Pro GPS Speed control (Cost friendly)

[CrashCourse316]

I recently started working on for a more cost friendly approach to adding a gps speed control to old boats that can't justify a $1100+ PP setup or even the RS classic package at $900. I saw some really old posts from a different forum and got in contact with the person who started it. Currently he's creating DIY Beta test kits in small quantity and selling them at cost + shipping(around $200usd). I hopped on board and am helping with the code to make it all work. we just hit the waters for some testing this past week (clip below). If you are interested in a DIY GPS speed control let me know and I'll send you the info for contacting. the actual unit has been dubbed SteadyPass as seen in the photo.

Disclaimer...hes pulling his kid tubing while testing the system. so there's a few surges and dips on the hard turns, but hey..better than nothing.

I’m interested. Has there been much testing or any issues?

Take a look at the youtube clip from my first post. I've been running it on my MC 280 sst with twin engine. It is still early testing and requires some manual tuning since we haven't had enough testing to find a universal setting yet. To put the progress in perspective though. He has had the units for a few years but didnt have the greatest code running it. In the last month or so we have completely redone the code and water tested the project. It is functional as a GPS or rpm control and keeps within 1 mph of target speed about 95% of the time as long as your not trying to mess with the system And if the water is smooth it does even better than that. The clip shows where it's at right now And it works very well for the current phase of testing. Now it wont replace those tournament level devices we all know of just yet as they have been in the market for 20 years with thousands of hours of refining. But we are working on it

Oh, sharp turns surge a bit. I haven't coded in adjustment or detection for sharp turns yet. Turns that dont dump your speed dont have an issue though.

super interested does it matter if it is carb or fuel injected?

[CrashCourse316]

Nope doesnt matter. It will run on any mechanical throttle input. No throttle by wire. We supply the main unit and code. You do the installation and other parts however you see fit. Buy your own servo and bowden cable, I personally went with the home depot parts for $5 to hookup to my twin engine.

EDIT 2/7/2019: Throttle by wire is now in engineering phase.

Nicely done - I don’t need it but will keep an eye for buddies that do (there’s at least one).

can it work with an outboard?

In theory yes, I haven't attempted installing the hardware on an outboard. The main unit needs a cable run to the servo for data, the servo needs power, normally it will run off 12v but an outboard throttle you might get away with less if the throttle body doesnt have a heavy pull. You would have to do a little more work on getting the hardware setup to your engine. The biggest thing would probably be figuring out how to mount the cables to the throttle. What engine do you have? Or could you post some picture of your setup?
