does anyone have an older mud buddy with a push in trailer pin?
I have one and with multiple straps holding the motor down on the pin , it still manages to work it's way loose
bouncing around on the road the pin wiggles out and motor will drop when fully disengaged

I see the newer motors have pin that locks it in place, this motor has not room for a pin,

anyone have any luck with a better idea ?

Maybe you can make something like this?
It'll lock it into place.

I have a 2007 model and had the same issue. I ended up drilling a hole and using a hitch pin just like the picture and now it works great.

where did you drill a hole? the round hand grab knob fits flush against the side of the housing, there is no kind of extension
off the side of the motor, to drill a hole thru.

or did you drill the pin inside some how, don't see how I could get to it,

I guess I could weld on a metal tab, and then pair drill them to fit a pin thru. the trailer pin

Ahh. You'll have to take the concept and get creative since the collar isn't part of yours.

Weld a hinged "L" to the frame that flips out and sits against the ball. Use a zip tie, velcro strap, or rubber band that keeps the "L" from moving. It'll keep that pin from backing out.

I drilled through the outer collar and thru the pin at the same time. Get a carbide tipped drill bit and go easy with it using lots of cutting oil. Do not force it or you will end up breaking the bit off.

replace it with one of these...
