Well finally. After much *****ing with my wife she finally let me buy a boat (after i cleaned the house out of all the rubbish we did not need.. never again) Anyway i got a 4.3m runabout with a Mercury 650 Thunderbolt Ignition 65hp motor (really old i think 25 yrs or something). The engine runs fine.. bit smokey but i put to much oil into the petrol i think! Everything works cool! All i need for the boat is a new canopy and raised window (bit low for my liking).. I just bought a set of instruments.. A yamaha speedo, an SW tacho, SW ammeter, SW hours meter!<br /><br />I think i can manage hooking the ammeter and hours meter up but im having some trouple hooking the speedo up! Someone told me that theres a similar nozzle that is on the back of the speedo on the motor which you connect to. All i have found is a hole which is near the bottom (i.e maybe 30-60cm up from the propellor) on the shaft wich i can't connect the tube to! Do i need to buy some special connector or something for the boat? links if you can help please to<br /><br />Also how do i go by hooking the tacho up to the engine! Anyone with this engine.. where are the outputs pls?<br /><br />Thankyou
