That Mercury head looked damn scary-one of those things when you are buying used is impossible to see.

Tnx Justin

Cool video. That's an insanely big (and busy!) boatyard.

Really nice boats. Hate to choose ❤

Good video. Amazing how many computers are installed on boats, cars, and everything we use now.

Many thanks for Great Videos first. I‘m watching from Germany Hamburg. My Volvo Penta GXI GF 2006 Start Bad, if it is warm. If i turn the hot engine off, wait 10 Minutes, and try to start, it start only with 1/2 Throttle. Gas Pumps already new. Gas Pressure Switch, and map Sensor also new. Any Ideas? Many thanks Volker

Hello, I have a 2020 mercury 200xl DTS v6 with code shift actuator AB difference,and 1 year ago the dealer replaced my lower unit due damage from object, is it possible that they could have done something wrong to cause this? I took it to the dealer for this intermittent problem and they found nothing, but I still have same problems, long beeb ,crank but no saart and code 1024-6, is there anything special to do to align the actuator before removing the lower unit, like put in reverse or neutral etc. Thanks again.

Perfect, thank you!

I was resigned to the idea. Thank you very much for the help and great follow up. One more question, if you replace the MAP sensor does it require programming or can just change out and go? Thanks again and have a great week.

Follow up video?

I have a failed actuator from a 2021 Mercury 225 ProXS. I bought a diagnostic manual and checked the motor circuit and sensors on my test bench. Motor and mechanicals worked but the sensors failed the test voltages in all three positions. It seems the Hall effect sensors in the circuit have failed and it is not available as a repair part. Have you received any indication from Mercury that this part may become available so we don’t have to buy a $1200 part instead of a $100 sensor board. As an alternative, does Mercury or any other source repair or rebuild these units. I bet there are lots of them in trash bins.

I am also having problems with my 2020 200 hp v6 outboard mercury. Shift actuator A B position difference. Can you make a video to remove ,check or replace and install lower unit? Thanks

Much appreciated, standing by.

Justin, have 2021 250 Verado V8. Marine Max replaced shift actuator on starboard motor few months back and now have another fault . Checked all batteries 12.6v and 11.5v under load. Have cleared fault and want to use boat. Any thoughts? Thanks and enjoy your videos as I’m new to the Mercury world.

See this a lot one ones that had that upper crank seal leak. Oil destroys that gasket and it gets sucked in.

Hi Justin, my optimus display panel is totally dead (all black). there is power coming in through the PCM but the lights are dead. The 2 Yamaha engines don't move at all. I have the same Regal SAV33 boat. Whats your opinion on it? >I don't have a joystick<

Thanks Justin! Love the “service” length advice. Question: I found the 2 ACRs on my 2017 280 Outrage with small black wire connected to the SI post (no idea where the other end is connected) and no wire connected to the ground posts. No wonder the ACRs led lights never lit up and house batteries were not charging off the mercs. Any idea why they were set up this way?

Great video with the Merc throttle body gasket, and also the Merc software with all of the computers on the boat. Cool stuff.

The boat version of eric the car guy! 👍

i had that happen a month ago..... someone did an alternator right before this happened. I'm guessing the cover wasn't put on correctly and the gasket just gets sucked in.

4 engines... Bet you want to take it out and run it....

That’s why I run 210 Cummins diesel single engine in my boat we don’t need any stinking computers and 4 miles to the gallon beat that mercury

Have a good 4th with your family Justin.

Good vid. Happy 4th

I think the odd looking yacht at the end is called a Bluewater yacht.

Killing it... Keep rocking on.❤

I like all of them

Could have done without that damn music... I'm out

Hey Justin do you ever have to fix Volvo Penta Joysticks? Any common problems you find?

This is awesome !!! Thanks for the clear explanation. You took what to me was a huge mystery and explained all aspects in a clear and concise format. I subscribed so I can come here with future Mercury problems.

Justin, I am trying to figure out which sensor part number I need I have a Pursuit 325 OS 2019 with 20 Yamaha 300s. I’m getting a port sensor issue and I’m not sure if I need a 5501 or a 5502 ?

Do you ever work on the east coast? Ft lauderdale

You make it look easy.. ❤

You’re a super Mcgiver!!

Yo Justin, you could get rid of half of those tools with one Swiss army knife.

I have a single outboard with the led blinking 3 red can I switch to the other output without changing the pcm?

A beauty!

Thanks for the sweet video. Trying to do this job one day. Is email the best way to reach you regarding questions? I sent one to you and not sure if it is the right email.

Where do I hook up my ground wire ?? I haven’t really looked. Boat at lake but I’m gonna put a relay on my 2 battery system ?

All that money and still have issues.... Ugh

Where is this sensor? Thank you

Hello, can you help me regarding this error? Water leak sensor trigger

You are definitely committed to your craft..❤

I have a 1720 Key West with a yamaha 90 2 stroke and the boat has two batteries. One to crank with, the other is the house. What is the function of the SI on the ACR and where does it connect? I read to put a fuse in the ground to the ACR and remove it when your boat is not in use, good or bad idea?

Ready for more!! Gel coat repairs ?

Today's video (like most of them) are perfect examples of typical boat ownership and things that need to be fixed (that most people would have no clue how to do, or they would prefer to hire you). Most people probably think that a mobile marine tech is just turning wrenches on engines - but you give great examples of a million other things that you have to figure out on the fly, and creatively fix, and try to often do in the single visit - with limited time and materials. Always great to watch you work.
