2003 model with less than 200 hours and blew #2 piston. It overheated and wiped the rings so I had zero compression in #2.

I had it re-sleeved, injectors flow checked and the #2 injector replaced. 20 hours later #3 piston does the same thing? Why is this engine so finicky? Many people have had this re-occurring issue as I understand.

I pulled the diagnostics from the computer and the High pressure pump is fine. the only alarm codes are from overheating but the buzzer never gets a chance to go off before the engine shuts down.

i think Yamaha should recall these engines and repair the problem. if they know what is causing the issue then they should send out a bulletin so people like me do not continue to waste money trying to fix a bad engine design!

Reason of review: Damaged or defective.

Monetary Loss: $2500.

Preferred solution: Let the company propose a solution.

Location: Huntsville, Alabama

I have the same problems, 200* *** outboard. Same piston is the initial problem.

Deciding whether to repair or replace the engine, sounds like your repair did not solve the problem. Thanks for sharing
