This is my First post and I am new to the site. I need some help figuring out my engine. the past four or five times I have taken it out on the water I've been able to get it started once or twice and it runs great those two times. However after those two starts and I go to turn the key, the engine doesn't even attempt to turn over, literally nothing happens at all. All other electronics on the boat work, I have replaced the starter, starter solenoid, rectifier, fuel lines, replaced the battery, and did a full carb rebuild. I am at a complete loss as to what could be the issue. PLEASE HELP!
