Re: 2004 Yamaha 200 HP Knock & Piston Damage (Pics Attached)
Ok, now I'm really stumped... I removed the powerhead, replaced the piston and reinstalled on the boat. I have hooked all the wiring harnesses up and now it seems like Im not getting any spark. The motor turns over great and seems like its getting fuel. I have double and triple checked all the connectors and ground wires and it seems like I have everything connected right but the boat wont start. I used an automotive in-line spark checker and I do not get anything. I have researched and found other comments on "homemade spark checkers" but I would assume this would work like it does on a car. Any ideas? How would I check for power to the CDI unit? I have also checked the lanyard and as soon as I remove the buzzer goes off so it seems to be working. The boat ran perfect other than the knock sound before I started this adventure so I dont think there was any preexisting ignition or fuel issues?
Any ideas? Thanks for the help.
