My boat is missing the fuse & relay cover, was curious if anyone with a 2009-ish (2008-2011?) MCX could get a pic of it to see what's what.

TIA!

Long story short…we get to our campsite at Lake Powell 30 miles from the marina, set up camp and then go out to do some boarding. Engine starts fine, we idle about 100 feet away from our anchor and the engine sputters and dies. We end up being blessed by some VERY GENEROUS pontoon boaters towing...

I have a 2006 XStar with the 350 MCX Vortec that has been throwing the Crank Position Sensor code for 3 months. I was told by my mechanic it could be replaced with a sensor from autozone as opposed to spending $230 from Mastercraft. Replaced the sensor but still get s check engine light and alarm almost...

New to TT... need guidance.

Purchased an '05 197 with MCX motor this year. Recently had a low voltage alarm so I put a new battery in the boat (bluetop optima). I'm hoping this solved the problem because the old battery was junk (7.8v after pulling). However, before I leave for the long...

On the prowl to purchase a well maintained 07-10 X15 with a MCX. What's out there? Located in Cincinnati but willing to travel for the right boat.

I'm in mourning because I never thought I'd sell this boat. I custom-ordered it new and have cared for it meticulously ever since. All service done at local MasterCraft dealer. The red, white, and blue color scheme is timeless but now, the kids are off to college, and I'm not just using it as much as...

Hey Guys,

i have a little issue with my MCX.

When the engine is cold, the idle is very rough (between 650 and 900 rpm), it often dies but starts directly.

As well, the engine dies when i put in a gear (no matter if forward or reverse).

Once the engine...

I'm looking for a little help with my Engine Cranks But Will Not Run issue. To the punch line, Diagnostic Trouble Code = "(81) Pump Low/Open". Intermittently starts and runs (as opposed to intermittently fails).

Background: 2004 197 TT w/5.7 MCX engine. 900 hrs. Pulling a...

Boat motor limits itself to 3000 rpm. starting from dead stop to wide WOT will rev to 3500rpm then back to 3000rpm, temp 135deg, oil 80psi. I checked wiring from temp sensors, seems ok. motors sounds fine and pulls nice until 3000 rpm the beep from rpm gauge, then limited rpm.

Hi all, can you give me a hint where the serial number of the Indmar MCX 5.7 engine (2011) is located? Its in a X2 2011. According to the manual there are two locations, but I did not manage to spot any of them. If there was a visible sticker, its probably gone so I would like to know the location where...
