I just wanted to say "thanks" to everyone here, particularly Clams. I just got my first boat a month ago, a '69 Hewes Tarpon with a '72 Merc 650. The 650 would turn over but wouldn't start. I spent two weeks reading what seemed like every message here. I printed out a few, took them out to the boat, and performed the tests on the switcbox that were described. The tests indicated that the box was bad. I bought a new box, put it in last night... went out 30 mins ago, pumped the bulb, lifted the cold start lever, turned the key and 3 seconds later WHAMMO... started right up!!<br /><br />Now I am going to do all the PM stuff I have read about here, but this forum just saved me thousands of dollars!<br /><br />Eli
