merc 470

[cfelton]

Yep, Ive gotta 170hp/470 merc. I just rebuilt the whole dang thing myself. They're pretty simple motors, but built tuff. After I got it all together and running I installed a pertronics ignition and it made a world of difference in starting and performance of my engine! I would recommend it to anybody. I kept my old points as a standby.So far as the ticking,check your timing,if thats okit could be a lifter going bad. try some Marvil Mystery Oil ,It usually quietens them down. Try to pinpoint the noise,open the oil fill on your valve cover while its running,see if it in your valve train or not.
