Does anyone know how or if i can fit a speedo easyily to a Mariner 40 2 stroke. sorry if this sounds like a stupid question but i am new to the boating scene.
a speedo is seperate from motor and works off air<br />pressure. not real accurate though. GPS is better<br />way to go, but a bit more expensive.<br />good luck,<br />M.Y>
I run a 94/60 Mariner.This engine has a manometer type (water/air pressure with tube) speedo hookup just forward and below the lower swivel mount. Yours may be the same, otherwise a seperate mount of the same type or paddle wheel style are both easy to install on the hull. I have a gps as well and as long as I keep connections tight and pick up hole clean on the speedo the gps agrees quite closely to the read out on the gauge. Good Luck and Good Boating <br />P.S. There is no such thing as a stupid question.
