Customer Question

My 2002 merc xr6 won't plane out anymore it will go to 4000rpm, when my wife moves forward on the boat it will plane out and go to at least 5000 rpm.
JA: Sometimes boat issues seem like they'll be really complicated, but end up being easy to fix. The Marine Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so the Marine Mechanic can help you best.
Customer: The motor needs to go at least 4200 to plane on its on, sometimes it's ok.
JA: Is there anything else the Marine Mechanic should be aware of?
Customer: One morning it happened then later about 30 minutes it was ok.

Has the prop or the gear case been changed recently?

Have you already done a compression test on the engine?

How about spark output usingna timing light on all 6 wires to make sure they can make the timing light flash?
