Nautic laugic GPS Speedo conversion

[DaveM]

Have any of you converted your paddle wheel speedometer to a GPS unit by Nautic Laugic? I have a 2018 Craz and can’t find the connection in the rear of my boat to install the GPS unit. I really don’t want to remove my floor. I think I need the NL4 unit.

It's the pigtail off of your triducer, should be right under your transmission hatch. Look for your paddle wheel on the bottom. I did it to our Mojo. Worked great.

I installed the Nautic Laugic NL4 SR on my 2018 Craz. The GPS speed registered is right on, but, when using cruise control at 17-20 MPH, the speed now seems to surge some, with the engine constantly trying to speed up then slow down. Actual speed varies by 1-2 MPH. This is not an issue at both slower surfing speeds and higher (30+) for skiing. Only when wakeboarding. Maybe boat is trying to plane, but I don't remember that issue with paddlewheel.

How is your upgrade working.
