Engine turnover issue on 2016 242 LSE

[fraserjr]

Anyone having intermittent issues with the engine hesitating to start intermittently? I have a 2016 242 LSE with 33 hours on it and in two separate occasions I have had one engine hesitate to start after anchoring. It first happened on the port engine after running them for about an hour at low speed and then anchoring. The is happened on the starboard engine yesterday after an hour of cruise and slow speed driving after sitting at anchor for an hour. The engines turn over but continue to do so and don't seem to catch and then just stop. On both occasions, if I wait a minute and try again they fire right up but I don't want this to be an indicator of a bigger issue, any thoughts?

I don't think it would be bad gas since I have gone through at least 1-1/2 tanks of fuel since it happened the first time.

Sounds like a fuel pump issue or something like that

I've had it happen 2 times on my starboard side. Did you have your blower on before starting?

When you say the engines turn over then just stop do you mean it stops cranking while the key is still engaged? If that's the case it sounds like a contact on the hatch switch. Next time that happens tape a nickel over the switch or have someone hold the hatch switch all the way down to see if that corrects the issue. If it's just an ignition issue it could be the lanyard switch in which case you could hold the switch all the way in the up position while crankin the motor.

this happens to me periodically i do not worry about it as it has never failed to start

Are you letting the blowers run for a couple of minutes before starting? I get the same hesitation if I don't allow the blowers to run. I have made it a habit and it hasn't happened at all this season.

My blower goes on automatically with the key turn and runs for 3 mins. I almost always let it run for at least 2 mins before I start them up and I did on Sunday as well.

I have push button starters on my boat, and you do one engine at a time. Both times it has happened, the first engine fires right up and then the send cranks, the guages flash and then it just stops. If I try it again immediately, it has done the same thing. If I wait one minute and try again, it fires right up.

I don't have the same engines, but over 10 seasons I just have to bump the key to start the engines. This would be annoying on a new boat.

I'm sure you must have thought of it already but could it be a battery issue? Would emergency parallel (temporarily) cure intermittent starts? (I kind of doubt it but who knows, may be worth trying)

This is possible if the batteries are marginal they may not have recovered enough after the first engine start to start the second engine. The minute or so you have to wait may be just enough time to recover the battery for a second start. Worth looking into connections and have batteries tested.

I crank both my motors nearly immediately one after the other - never had an issue. Even with a low battery a few times, talking like 11.8 volts on the Connext - they both will fire up one after the other. I think as long as one motor is running the system is creating enough cranking amps for the second motor to start.

Sounds like a wiring issue or something else. Doubt its fuel related because you would have consistent issues with a bad pump or water in gas. A lose wire could just be jiggling around and coming undone and then reconnecting / corrosion might be building up on something.

Don't discount fuel issues as each engine has its own fuel delivery system from the fuel pumps to the injectors but from what you're telling us, that it starts after about a 1 minute recovery, I still believe it's electrical.

I thought it might be fuel but I have gone through at least 1 1/2 tanks if not more since the issue first cropped up. I guess there could be crap sitting on the bottom of the tank that might be causing it.

My baby going in tomorrow morn, for her 50 hr maintenance. I'll ask my service tech guy if he has any idear's.

This sounds similar to the heat soak issue or exhaust backpressure that guys are having after wakeboarding. I'm not sure if they figured it out, but I think running he blowers helped if it was a heat soak issue. Do you run a lot of ballast? I think they were under the impression that the extra weight on the ballast side caused an exhaust backpressure issue. Not sure that either one is your issue though.

Happens to us all the time when we leave the key on and push the buttons to stop the engines. Very inconsistent and can happen to either engine. But if we turn the key off wile floating around 'almost' never happens. I've gotten pretty used to it as they eventually always do start. Lots of times it cranks starts momentarily then dies 4 or 5 times before a good start. Once in a while cranks the full 10 seconds then times out without firing. Dealer has never heard of such a thing and can't duplicate. We have about 145 hours on engines...
