Mercury opti max problems


Recommended Posts

I bought a new boat in January I've got around 20-30 hours on the motor it's a 2018 150hp Mercury Opti Max. A couple weeks ago I took it out when I first started the motor it would run then die it seemed hard to get it in gear before it would die finally I got it to stay running never had anymore issues with the motor dying that day after it warmed up. I figured it was bad gas. Today I took it out to lake of the ozarks ran from Coffman up to the the little gravois while idling into the shallow water the motor started to sputter then it died it would start then die then it wouldn't even start. I pumped the bulb and it started up and ran good for about a hour then did the same thing. I'm thinking fuel pump it should be covered under warranty. Is there something I should check or am I overlooking something.

My relatively uneducated guess is that it could be some type of leak in the vacuum system for the fuel...if not the pump itself.

I'll have to check. I was getting a low voltage warning on my hummingbird. Would that cause my fuel pump to not get the voltage to work properly?  It did seemed to die after running awhile so the motor should have charged the battery. The low voltage warning would go away after it ran awhile. My boat was at the dealer for 3 weeks getting a jack plate installed when I picked it up I went straight to the lake so it was off the charger for 3 weeks but it was charged before it went to the dealer

An unstable ground connection can make all kinds of weird stuff happen.   Your discription of the issues you are are having make no sense (mechanically), and anytime things "don't make sense" I automatically start checking ground connections.

You say that you pumped the primer bulb and the motor started.   Were you able to pump it more than 3 full squeezes?  If so then you may have fuel pickup pump issues or a restricted/leaking fuel delivery hose.  If you didn't get 3 full squeezes then I doubt the squeezing of the bulb had anything to do with it starting afterwards.

None of this matters though because at this point in its life nobody can touch it unless they work for a dealership.   So take it back to where you bought it.

Now that that's out of the way.....did you remove any fish from Lil'Gravi ?  If so I'm done talking to you 😊

I was up your way Saturday morning. My brother came to visit and I was trying to get him on some fish and hoping for some topwater action. We couldn’t buy a topwater bite. I did manage a couple pretty decent fish way up there. One with a Craw and one on the worm I showed you. Both decent fish and all the shorts were released quickly and unharmed, ready to be caught and released again 😁.

I did catch some nice fish up the little gravois had bass chasing baitfish near the last docks before getting into the creek we would catch a few then nothing for awhile then catch more then nothing. I think my dad caught 4 on 5 cast. Most around 2lbs had some long skinny fish. All on spinnerbaits. Caught a bunch after dark on 10" worm on the main lake area around Coffmen kinda rough water out there last night. I wonder if fireworks affect the fishing. I left all the fish.

We got'em pretty good yesterday evening.  Still eating that spinnerbait.  No bigguns but a respectable limit.
