What You SHOULD KNOW about CAP & ROTOR for INBOARD MARINE ENGINES

In this video we show you What You SHOULD Know about Cap & Rotor for INBOARD MARINE ENGINES. Don't do the same mistake we did by using a cheaper cap & rotor bought from an auto parts store. It may work well for a few months, but after that they will corrode. Making your inboard Marine Engine sluggish, loss of power, and unresponsive. You need to use only Marine Parts, like QuickSilver for Mercruiser 5.7 MAG MPI, etc. The marine parts will cost a little more, but well worth the price in the long run. Make sure you use SAE MARINE J1171 for all Electrical parts! Protect your inboard marine engine!

So glad you pointed out to use OEM ignition parts. Basically our I/O's and inboard motors sit a moist sauna all the time. So yes spend the extra $20 the get OEM cap and rotor. Could mean the difference great day on the water or limping back to the marina or getting towed in. You mention about using automotive alternators. Yes they will work but alternators must be tested for proper ignition-protection to suppress spark in order to be certified for marine use. Automotive alternators are not, and they can create spark exposed directly to the enclosed engine compartment. Great video and editing!

[@KeysBoatingChannel]

Thanks, Mark! Perfect comment! This will help everyone avoid the headaches of using non Marine aftermarket parts or Non SAE Marine J1171 for electrical parts. Thanks for watching! Thanks, Bro! Peace!

[@BEARLY-BEHAVIN]

Brother! Out Standing. It actually looked worse the what I had imagined when you were talking me all about the issue. Wow. This should help many. Awesome video my man. ❤❤❤

[@KeysBoatingChannel]

Thank you so much my Brother! Hopefully it should be fine again. Ready for some more sandbar adventures! Blessings! Peace!

[@MiamiBroChannel]

Great video bro. You explained and recorded everything well. And I agree with you 100%. Nothing electrical should be after market parts because you would have corrosion issues in just weeks. Thanks for sharing your experience and making this video.

[@KeysBoatingChannel]

Thanks Bro! Great comment, thanks! Blessings! Peace!

[@KeysBoatingChannel]

This video can save you Money, and headache's from doing the same MISTAKE we did. Hope this video helps make the right decision for the parts you need to maintain your Mercruiser or any marine engine. Thanks for watching! Peace!

[@ferndogcreamator7610]

Infamous salt spray gets in everywhere

[@KeysBoatingChannel]

Hi! Right, that Salt get in all the way into the distributor cap...and then everything else. Thanks for watching, and comments! Peace!

[@jamesmelvin1991]

I really appreciate the individual

[@rebuilthip7825]

Good to know done filters plugs/wires/rotar and cap

[@KeysBoatingChannel]

Awesome! Thanks so much for watching our video! How does it feel after all service done? Peace from the Keys

[@gm1937]

Auto parts are NEVER a substitute for marine grade original OEM . Not only will it void your engine warranty but CAN also cause electrical sparks and even an explosion under the right conditions. If you want to do it yourself get the manufacturer service manuals and follow the maintenance and repair procedures by the book. That’s what I do and never had a problem.

[@mehmetyavuz4055]

I have rhe same boat but 7.4 mercruiser engine and the boat shots of while im driving and the mechanic couldn't find the problem do you know what problem can couse that?

[@KeysBoatingChannel]

Hi, what exactly is it doing when driving? Thanks for watching our video! Peace from the Keys!

[@bradysully5755]

So if I’m bogging down only when under load, should I check this

[@KeysBoatingChannel]

Hi Brady, it wouldn't hurt to check your cap and rotor...it could make all the difference. Best of all its very easy to check it. Thanks for watching our video! Peace from the Keys!

[@GavinBrown-n2y]

All dissy caps do that! Your engine has computer controlled timing, BUT, it is sensitive to the dissy position, I can see by the angle of the flat section of the cap, is parallel with the inlet manifold, this shouldn’t be, it needs to be more wedge shape, to be in the optimal window to help the computer timing.

[@KeysBoatingChannel]

Hi, thanks so much for watching our video! Great information thanks! Peace from the Keys!

[@DrEd-th2lu]

Never put automotive parts in a boat that are fuel or electrical related. Not only for the problem you had, but insurance may not cover you in a fire 🔥 or explosion event after the investigation. Something many people do not think about….

[@KeysBoatingChannel]

Hi Dr Ed, thanks for watching and your comment! You are absolutely right, this is great information for those who have Insurance. Thanks so much! Peace from the Keys!

[@cguy7297]

I trailer my boat and never goes in salt water...and true that some part have to be brass or stainless because of salt...but my truck engine gets wet when I drive it down the road and my boat engine has never gotten wet it's an I/O so the marine parts are not necessary as far as in concerned

[@KeysBoatingChannel]

Hi, thanks so much for watching our video! Great information, thanks! Peace from the Keys!

[@MooreFishing-ky3wq]

I use electrical grease to help corrosion .

[@KeysBoatingChannel]

Hi, thanks so much for watching our video! Yes, great idea! This info will help others! thanks! Peace from the Keys!

Napa cap and rotors have brass contacts beter than oem

[@KeysBoatingChannel]

Hi, thanks for watching our video! Yes, I also thought the same. Peace from the Keys!

[@travisconner1581]

I bought the oem brass one and it didn't really fix the issue.

[@KeysBoatingChannel]

Hi, if changing the cap and rotor did not help, then next is your coil. Best way to have mechanic read the codes on your engine to pinpoint the issue. Thanks for watching our video. Peace from the Keys!

[@travisconner1581]

@KeysBoatingChannel i don't see how a boat engine from 2019 with 150hrs on it that sits on a trailer in the garage could have ignition components worn out already. I changed the cap initially because it came with aluminum contacts

[@travisconner1581]

Looks like its only $30 for a coil....maybe that's the issue. Cheap shit.

[@grasscutter88]

Mine had aluminum from the factory

[@KeysBoatingChannel]

Hi, thanks for watching our video. Did you have any problems with it being aluminum, and are you in 100% saltwater conditions? Thanks, Peace from the Keys!

[@grasscutter88]

@@KeysBoatingChannel Yes sir. I took some sandpaper to mine and it still has the misfire. There sure is a big price difference between this caps. Me taking sandpaper to the contacts didn't make a difference.

[@grasscutter88]

Mine starts out okay, but then it starts missing once it gets warmed up. Its actually always had a slight miss, but was only noticeable on the trailer listening to the exhaust but this year it actually misses more noticeably and stumbles periodically when I try and get on plane. This was a drop in engine that got installed at the end of 2019 Nothing has been done to that cap other than me sanding off the corrosion, but the boat only has 150hrs.

[@KeysBoatingChannel]

Wow, yes, we learned our lesson the hard way...but never again would buy nothing but Quicksilver because the difference in performance is big, and last longer. Thanks for sharing your experience. Peace from the Keys!

[@grasscutter88]

@@KeysBoatingChannel I'm going to call the place I bought mine from and complain because I'm pretty sure it was advertised as being built with marine components. Brass freeze plugs, marine alternator, starter, ignition the whole nine yards etc.
