Speed log wrong location

I recently replaced the speed log paddle sensor in my, new to me, 30 y.o. 25' mono-hull. It's location is about mid-way along length and mid-way from keel to water line. The paddle sensor doesn't see full current and hence doesn't move until water speed reaches approx. 2 kts. As far as I can tell it's always been in that location so it's never been accurate. Any recommendations on finding a better location?

Forward of the keel and on the centre-line if you can

What hoolie said.

Fin keel sailboats: Mount to the side of the centerline and forward of the fin keel 300 – 600mm (1 – 2').
Full keel sailboats: Locate amidships and away from the keel at the point of minimum deadrise angle

Re: Speed log wrong location

If possible position the wheel so it is not directly in line with the lifting sling. Lots of paddle wheels get crushed by lifting slings. Our paddle wheel is right in line with the forward sling and when the boat is hauled I have to remember to pull the sensor and put in the plug. I forget about half the time. So frustrating...

Re: Speed log wrong location

Thank you, thank you all. She's a full keel boat and the sensor is at min. dead rise now but you all gave me an idea. I have a capped thru-hull up forward (previous head waste) that I'll move it to. It should have less interference from keel and I don't have to drill another hole. This will probably put it under the lifting sling but I'll have to remember to pull it.
