Very thorough overview of that system, true, professional at work

[@JustinLeeMarine]

Thank you 😊

[@wdt5419]

my friend im going to school to become a marine technician and your videos help me keep in mind why im doing it and the career I want. Keep up the good work!!!!

[@JustinLeeMarine]

Thank you, I appreciate that. We need more people like us in the field 😊

[@610boating5]

Wow that is what a pro troubleshooter looks like, when paying by the hour thats much appreciated.

[@JustinLeeMarine]

Thank you. I appreciate that ☺️

[@jplazo5862]

Thanks Justin. I’m looking at 18- Realms and this was an education on what to look for or ask about.

[@JustinLeeMarine]

Just make sure the steering is up to the newest version. They seem to not have problems.

[@bakervinci163]

I thought I wanted a joy stick. I have enough crap to keep working ( livescopes/ power poles/crappie brakes/jack plate/ move trolling motor and the the two trollers on the brake system).

[@bakervinci163]

I’m surprised that does not have lithium batteries. I guess speed is not an issue for them

[@A5JDZK]

Good info, as always. Yamaha, for the win!

Hey Justin, great video just like your others on JPO engines. I have triple 350 verado with JPO. I have been fighting all of the issues associated with it. I have replaced all pumps to Gen C but still have Gen 1 actuators. The most recent pump replaced was the port engine and I have put 20 hours on the boat since and I am still getting critical steering reduced codes for the port engine and now I can not get it to clear. I checked almost everything you mentioned. I was unaware of the fuse for the actuator so I’ll try to locate that. I have two questions for you though. If my two engines are able to move the port with cable could my actuator still be bad? If I replace the actuator with a gen 1 will I still need to get it calibrated? I am in North Carolina and have a trip planned to Bahamas in less than two weeks and I’m about to have a panic attack. Any help is appreciated. I would even be willing to trailer my boat to you in Florida this week.

Hey Justin, This happened to me the other day and it locked the starboard engine steering to the left. Is there a way to manual override to get the engine back to center so I can get back to dock with just the sticks and no steering?

Hi Justin, I currently have my Searay 280 up in Port Richie at American Marina. My wife and I are searching for a better dry storage marina a short distance from the River Walk. I’m not looking for a yacht club just a better dry storage place. Any suggestions?

[@johnm5714]

That looks like it’s gonna become a $5000 repair-and exactly why I won’t buy a new new boat.All that electronic equipment is beyond complex and will become problematic. Only a matter of time-and usually right after the warranty is up. Nothing like a nice pair of Yamaha 0X-66s that have been taken care of😆

[@JustinLeeMarine]

It is getting more and more complicated. Electric everything. The OX66 is becoming a rare breed now.

[@BG_Lidar]

Hey Justin, another great video. Very impressed with your diagnostic "process". How much of your troubleshooting is based on having seen similar issues versus following a prescribed manufacturer's (Mercury in this case) fault tracing process?

[@JustinLeeMarine]

That is a very good question. It really depends on the situation. When you do this job for so long you run into a lot of the same problems. The first gen steering systems are known to be problematic so you see them more. I usually call Mercury if something is under warranty or if I do have something I have never seen before. Just recently I had a bad CCM(triple engine)that was blowing all the main fuses because it was shorted out. I had to get Mercury to help me with that one. 😊

[@bakervinci163]

Just lock trouble shooting power poles

[@gregimo2877]

Hi Justin thank you for very informative guide, would like to ask you do you think hydraulic steering or electric is better as I am about to upgrade to 2 new 250 verados thanks in advance

[@JustinLeeMarine]

I would go with electric steering at this point. Hydraulic is starting to be outdated. Everything is becoming full electric. It will also be easier to get parts for the newer stuff in the future. Just my 2 cents 😊

[@gregimo2877]

Thank you for both replies 🙏

[@bakervinci163]

Voltage first

[@paullapinta6367]

Justin, what year were those engines? Do all Mercury engines have that complex a steering system? Thanks

[@JustinLeeMarine]

They are 2018-19 and they are complicated if they are the Joystick Piloting version. The brand new ones are fully electric and don't have the hydraulic pumps anymore.

[@paullapinta6367]

Thank you for the quick reply. We are in the market for an Everglades or whaler about 30 feet. Seems like these have these Mercury engines or older V8 Yamahas which have their own issues(flywheel). Might have to look at 28 or 32 Pursuits, using more reliable 4.2 Yamahas. Thanks again.@@JustinLeeMarine

[@gregimo2877]

Oh and is it worthwhile to get the Joystick

[@JustinLeeMarine]

It does make the boat much more maneuverable.

[@natekons]

Terrible boat layout. So many electronics in the bilge. Destined to fail by it's design. Batteries in the bilge as well? On such an expensive boat.

Job security 😋
