Re: New Honda 2.3 outboard not running
The warranty can't be "voided." It it technically and legally impossible to do that. Honda has a legal obligation to repair any factory defects, and just because you elect to try and do some repairs does not excuse them from that obligation, period. You can change your own oil, take it to another non-Honda dealer, use non-factory parts, etc. The key caveat is as long as your actions aren't shown to be the cause of any failure or problem with the outboard when you want Honda to pay for warranty repairs.
In short, if your repairs damage or break some part of the outboard and then you expect Honda to pay for it, they will probably decline. If some other original or genuine part of the outboard is broken and it is determine to have a factory defect, Honda will likely pay for the repairs.
If you think there is a genuine factory defect, for sure, have a Honda dealer inspect it. Be sure you communicate with the dealer who is paying for what BEFORE any repairs are made to the motor.
Caveat: I work for Honda, but the preceding is my opinion alone.
