Mercury Optimax Outboard testing

[@brianpung9693]

Nice video. Swivels and swivel sockets are a must when working on outboards. And tools are only as good as the person using them

[@OutboardDad]

@@brianpung9693 I agree, the tools do not make the mechanic. Appreciate your comments

[@OutboardDad]

I agree, the tools do not make the mechanic! Thanks for sharing

Nice Part 1 video...the adventure continues

[@OutboardDad]

Thank you, let’s get together and do a video about your boating experience.

[@davidgibson8292]

Can you do a video of cleaning the vst tank on a 2006 mercury optimax please thank you. The one with out the big red filter

[@OutboardDad]

@@davidgibson8292 Hey David, I sold that motor, there is a VST on the Yamaha I have but I am in the middle of a few projects now so will be some time before I get to it. If you want tackle yours you can send me some pics while you are disassembling and I can help you. My email [e-mail]

[@davidgibson8292]

@@OutboardDad thank you so much sure will .

[@luie302]

Thank you, very well done.

[@OutboardDad]

Your welcome, let me know what you want to see next

[@biodot88]

Good stuff thanks! Definitely go with a true spark plug wire removal tool or you’ll mess up the boots. So much to cover here. Inspecting reeds, fuel and air pressures etc. did you ever get the actual hours using vessel view?

[@OutboardDad]

@@biodot88 yes and thank you, has 44.4 hrs!

Hi. Thank you for the great vid. My 115 was standing for about 7 months with about 4 flushes over that period. I took it to the river over the weekend and for some reason it is in limp mode. No alarms just limp mode. Any help?

[@OutboardDad]

@@ryantait177 what is year make and model?

[@ryantait177]

115 ELPTO Jun 2007 Mercury Optimax KW 84.5 Max RPM 5750

[@OutboardDad]

@@ryantait177 Beat would be to get a diagnostic tool on it to see. I would need to look in my Merc book and see the things that put it in limp mode. Overheating, lack of oil pressure, fuel and air pressure tests need to be done

[@ryantait177]

Thank you. My friend suggested that it might be the high pressure fuel pump. I will have to take it in. Thank you for coming back to me.

[@OutboardDad]

@@ryantait177 Anytime, fuel press test is easy, Autozone will let you borrow the gauge tool for free

[@jaredgreshow2459]

I am in the market for a 2005 or newer 115 and having trouble finding any worth while and within my budget. How can I get ahold of you to maybe get some good places to look besides Facebook marketplace?

Great Vid, have a 200 opti that I did a total rebuild, however I think one of my temp sensors are bad, did not replace. Put engine on my ddt and got no reading of running hot, do you know how to test temp sensor, can't find int he manual, ohm test?

[@OutboardDad]

@@mercman2.5 OK, best I understand is if you go over temp it grounds. You can remove and dunk in boiling water and test with meter. A little tricky so may be easier just to replace

[@mercman2.5]

@@OutboardDad Got one ordered, thanks for response!!

[@OutboardDad]

@@mercman2.5 good luck! Let me know how it works. Remember, Free outboard buying guide to my subscribers! $20 value just email me [e-mail]

[@stephenbarkley7868]

Why would you think you would have a spark when there is no power to the ecm?

[@OutboardDad]

@@stephenbarkley7868 Good point, that’s why in the next videos I hook up a key switch. It’s only the older motors that would have spark that way. Sometimes I just think out loud. Thank you for your comment

[@dustshelldavis8557]

Great video

[@OutboardDad]

@@dustshelldavis8557 thank you! Let me know if I can help you with anything

[@Fearless_5280]

I have the same engine. What did you do to jump it out to preform compression test? Thank you.

[@OutboardDad]

@@Fearless_5280 yes, this way no spark when testing compression. In an upcoming video I go further into ignition and spark. Thank you for your comment!

Need to find a 200 Opti

[@OutboardDad]

@@davidgilbert5405 I may have access to one, where are you located?

[@adriangreen3462]

Hello, very nice video there :) I have a problem with my mercury 150 optimax. I have smartcraft and gauges connected to it. The smartcraft works fine, but the gauges only works once in a while. The voltage on the gauges drops to 1 and 2 volts. Have you ever had this problem and knows a fix? :)

[@OutboardDad]

Ok, always start with the basics, how old is your battery, cables? We can do some tests if you have a multimeter. May be better to talk on the phone

[@adriangreen3462]

@@OutboardDad hey again. Battery is new, and cabels are fine. Battery and generator have good voltage. Its only the gauges that lose the voltage.

[@OutboardDad]

Ok, let me know if you want we can face time or talk when you are working on it. Email me [e-mail]

[@Ben-z3c6y]

I would buy those for $400 all day. I live in S.E. Kansas

@@Ben-z3c6y Agreed!
