Re: Raymarine speedo question
After decades of messing with paddle wheels and cleaning up salt water in the interior as well as having my heart go pitter patter pulling and installing the plug I finally went with an Airmar ultrasonic speedo. They are the supplier for raymarine and you can buy it direct. It is a direct fit for the usual paddlewheel speedo ( but check your dimensions). Stick it in and done. Paint it with transducer paint but not to heavy. Other wise zero maintenance or headache. Wish I did this years ago.
