Trailer Posted March 1, 2013 Posted March 1, 2013 I'm mounting a transducer. Humminbird says if the prop spins clockwise in drive, mount it to the right. Just the opposite for counter clockwise. Without running my motor, from left to right...the fin runs from the back of the prop to the front of the prop if you are looking at the boat from behind. So it looks like this... / -- O \ Emphasis on the top fin. Which direction does it spin in drive? Quote
Super User Nitrofreak Posted March 1, 2013 Super User Posted March 1, 2013 Most all props spin clockwise as you are facing them in forward gear, but it would be better to know the drive system that you have and even a picture of the prop as you are facing it would be even more helpful. Quote
Super User slonezp Posted March 1, 2013 Super User Posted March 1, 2013 When you're standing behind the motor looking at the prop, imagine it's a fan blowing air towards you. Whichever way it would need to spin to blow that air is the rotation you are looking at. This spins to the right or CW Quote
Super User Nitrofreak Posted March 2, 2013 Super User Posted March 2, 2013 Yes like that one there, Thanx Sloan !!!! By the way that one looks like it's seen a sand bar or two LOL !! Quote

And people wonder why I bought another tin. I have 2 spare props just in case. New boat has an SS prop. I'm worried. I could buy 4 aluminum props for what a stainless cost. Picking her up tomorrow morning. Quote

It takes a beating with not much wear to show for it. My spare aluminum prop looks like a lawn mower blade after mowing a rock quarry. . . I'll stick with my stainless. Quote
Trailer Posted March 2, 2013 Author Posted March 2, 2013 Using the fan theory I'm going clockwise. My prop looks like yours slonezp...except I haven't hit any sand bars yet. Quote

Stainless props are awesome for sure, but the one thing to be careful or mindful of here is for the added strength you get means there has to be a trade off somewhere and it usually ends up being gear fractures or shaft damage.

Super User Wayne P. Posted March 5, 2013 Super User Posted March 5, 2013 Hold on!!!! For a transom mounted sonar transducer, it makes no difference which way the prop turns on an outboard or outdrive. The water has already passed over the transducer before it is affected by the prop. What you are referring to only applies to an inboard type boat that the prop is forward of the transom. Your only concern is the transducer affecting the prop if it is within the diameter of the prop so it doesn't aerate the water to the prop and cause cavitation. Quote

So, oh Wise Wayne, you're saying I have my pick of left or right and that I could mount it on that stair stepped part of my hull? That's how Tracker did the original. Humminbird instructions are talking about 15 inches from the prop, yatta yatta yatta.... Quote

Humminbird instructions are talking about 15 inches from the prop, yatta yatta yatta....The 15" statement is for INBOARD boat installs. I am not aware of any inboard Trackers with a propeller drive.Tracker was installing transom transducers on their stepped hull models in the wrong place up until the 2012 year models. If you want depth readings when on plane, the transducer has to be slightly below the hull bottom, not on the transom above the hull bottom. If you want a picture of the proper location for best performance, I can send you one. Just need to know what Humminbird unit you have and what performance you expect from it. Send me a PM with your thoughts. Quote

flipin4bass Posted March 10, 2013 Posted March 10, 2013 If you're fishing in the Northern Hemisphere the prop turns clockwise, but if you're fishing in the Southern Hemisphere it turns counter-clockwise. Quote
