Hi all,

Went on a sea trial yesterday, 2013 310 BR. Twin Volvo 380 HP Ocean X Joystick. 170 hours on engines/boat. Ran good until...

Took her to WOT and bounced off of 5,000 RPM, no where near WOT spec of 5,600-6,000. Topped out at 49MPH GPS.

Came off plane, opened the hatch, shot temps on engine, all good.

Went back on plane and about 3,000 got this error code MID 128 SID 8 FMI 14 on STBD engine.
No guardian kicked in, temps and Oil pressure good. Little vibration getting on plane.

Back at dock, engines with throttle only between 1200-2500 rpm STBD engine was rough/shak'n a bit. PORT was smooth as glass.

Being told that code is a spark/Valve/Cylinder issue?

I am pretty sure the wires and plugs are original. That being said could also be why she wont get to WOT specs?

Boat is Stock, props check out.

Any ideas appreciated. Always been a black motor guy.. not sure about these red things LOL.

Hoping not a bad Valve or cylinder issue.
Oil clean no signs water and no signs of oil in antifreeze.

Sounds like a cylinder is misfiring to me and probably at least partly the cause of only getting to 4900RPM at WOT. The Volvo engines share the mechanics as the black brand and are pretty bullet proof.

There's always a chance you broke a valve spring or worse but I suspect a bad spark plug/wire/coil. I did a quick search and didn't come up with anything but I assume the code calls out a particular cylinder misfiring (at least automotive misfire codes do)? I'd try swapping the sparkplug, coil, and wire from the bad cylinder with known goods ones from another cylinder and see if the miss moves. I've also seen after a hard run a piece of carbon in the cylinder dislodge and get caught in between the sparkplug center and side electrodes and cause a misfire.
 
Yes it called out #8. Mechanics are on it today. Then reschedule sea trial. Fingers crossed and I will be back in the family again after a short break LOL.
 
Bad plug number 8. Swapped with port motor and port alarm error went off. Stbd ran fine. Getting plug and will see if we hit WOT now.

so far so good
