Default Autopilot Compatible with Garmin 740S

Information online is a bit overwhelming and I can't figure out what I need. We'd like to be able to integrate into our GPS and would like to spend around $1k. Garmin has Compact Reactor 40 (w/o head unit) but I can't tell if this will work with the 740S or if I would have to purchase the head unit.

Any other brand suggestions? We really only care about autopilot being able to hold a course, but if we can integrate to our GPS and have it go directly to a waypoint, this would be awesome.

We have a 28 Albin with single diesel if this matters.

That is compatible ...but it has a 1 L pump....
For your boat you may need a larger pump.

The AP will have it's own heading sensor that will hold a straight course. If you want to follow a route you need to interface to your 740s, which can be done via nmea. Virtually any brand AP will work, but $1000 is not gonna get you much.

Thanks for the feedback. With Garmin, you have to spend $3800 to get the larger pump and if the 1.0 pump won't cut it, I might need to look into another brand. I'll spend more than $1k, but not looking to drop $3k on an auto pilot. On my last boat, I had a fancy auto pilot and I didn't use 95% of the fancy capabilities.

I really just want the boat to hold a heading while at cruise and trolling. Any interfacing with the GPS is a bonus.

The slower you want to go, the more important the pump is. As with most, you get what you pay for. What good is $1000 ap if it doesnt work as you need it? And then you have install time or cost to have it installed.

I have a line on an EV-150 that may work for you for a reasonable price. PM me if interested.

On your awesome Albin you will not be satisfied whatsoever with the performance of that autopilot. It is not designed for boats such as yours it is really meant for bass boats of 16 to 19 ft and use only at speed

On a large hull ..the small pumps will not last....

And no need to spend $3800..you can get a Reactor 40 with Smart pump for about $2750...I just got one...

Reactor40 Autopilot without CHS control head, Hydraulic w/Smartpump Corepack, MFG# 010-00705-68, with Reactor 40 9-axis heading sensor, SmartPump with integrated electronic control unit, Shadow Drive, buzzer, cabling and connectors. Controlled by MFD.

Okay, thanks for the tips and it sounds like I need to step up the pump size.

It's not just the pump. A number of members here tried it and were not able to make it work. The Garmin Reactor with the 1.2 liter pump will perform well in your boat.
