I have a 1987 70hp 3 cyl. Mounted on a 1972 Glastron 16 ft. I'm pretty sure it's got the stock factory prop. <br />What should the WOT be? <br />How fast should this combo go? I've clocked it at up to 36mph on a flat calm lake with my GPS. <br />The other question is why would the tach always bottom out at 1000 rpm when the engine and ignition are shut off? <br />The stator and rectifier were recently replaced/upgraded at a reliable shop, and before that the tach was totally unreliable, jumping around with no relation to actual engine RPM. Now it appears to work ok but always shows a minimum of 1000 rpm.<br /><br />Thanks<br />Grant
