2010 nautique 200 died- ideas??

[Rivvy]

Ok gurus. I’m looking for some help. My 200 shut down this morning and won’t restart. Running flawless then just stopped at 34 mph. Has oil, appears to have fuel pressure on fuel rail, lanyard in tact, has gas. I’m speculating an electrical issue? After work I plan to pull plugs and investigate and look for spark, check compression. Any other ideas? No codes were set on diagnostic screen initially. After trying to start a few times a low oil pressure code set.

 

Thank you in advance for any suggestions or ideas you may have.

Keep giggling the lanyard. My mechanic says he gets calls all the time where the final problem is the lanyard.

 

If that is not it call @Jody_Seal

Also check you ground wires.

[Rivvy]

If the lanyard is faulty, will the engine crank? My engine will crank but won’t start.

[Horton]

@Rivvy no I don't think so

I had a similar problem on a 2001 Nautique. Ran flawlessly, stopped at the end of a pass and would not restart. Turned out to be a bad battery cable. Check the big easy stuff first.

[jayski]

isn't there some big ole fuse that tends to go on the older model 200's?

[Keith_Menard]

First thing I always do is pull a spark plug and test for spark. Air, Fuel, Spark...but you are already doing that :)

I'd bypass the kill switch first just to rule it out, since a faulty kill switch allows the crank but no start that you have. Boat out of neutral is the one that won't crank.

@Rivvy The boat will crank, but not fire if lanyard is bad.

@Rivvy connect the 2 lanyard wires together, giver a try.

[Rivvy]

Lanyard is good. Negative battery cable seems to be good. No spark.

[Rivvy]

Rotor grenaded. Resolved. Thx for help. FYI motor will not crank with lanyard off.

Take it to you local dealer and get a new boat.

@Rivvy how many hours on it? I heard the rotor may develop problems around 500 hours.

[ski6jones]

That seems an unusual mode of failure. Which engine and hours? Just curious.

[jetpilotg4]

that would cause the problem

[KRoundy]

Easy fix. Well done. Curious like the others to know when/how that failed.

Seen a number of cap and rotor failure along with having to replace the dizzy completely. GM utilized a very cheap plastic housed distributor. I replace them with a aluminum housed model but if you do beware the better aluminum unit has machined screw threads for the cap and rotor where the cheap oem has self tapping fasteners.

Replacement distributors from napa or orliys run about ,$90.00

5.7L no warning just hatched. Wife was driving and just had a flowy pass. Boat died and didn’t get to finish my set. 1500 hours. I replaced rotor and cap with Napa ones. I did not know about an aluminum one. I wished I did. New one looks as cheap as the old. Way better outcome than I figured. Boat runs flawless again. 200’s just rock!

I find the marine cap and rotor (with brass vice aluminum contacts) last longer and are more reliable. Can get at marine supplier or Amazon ($20, search G.M. distributor rotor cap brass terminals)
