Looking for options what to put on Spark Plug wire Sleeving
 

So I have been busy for the past 4 months having spark plugs wires improved upon for the marine environment. ended up going with a sleeve material for one that holds up to heat very well and secondly looks really good on top of. I can have different color sleeving - red - yellow - orange and so on.

I think I am going with black and blue and red sleeves for starters. The sleeving has no writing or logos on it as you can see in the pics below. So my question is should I leave them plain ? or put a logo or wording on the sleeves ? I am basically taking votes for what is best to put or not on the sleeves ? What should I have put on the sleeves that would look great overall for the vast amount of boaters who will need spark plug wires at some point in time.

Below are the Merc Racing HP 525 and the Merc Racing HP 600 sci and Merc Racing HP 700 sci prototype spark plug wires but have been fully tested. Good to go on that end.

Jan 2019 - Moroso had a person fly into Dallas and wanted to meet with me -- inwhich we did. The jist ---. Moroso many years ago was in the marine biz as they made marine engines and of course marine oil pans.. Not many engines were built because they really and still are known for drag cars, auto hot rodding and the ULTRA 40 High Performance spark plug wires.. At that time - The owner of Moroso liked boats as well. He passed on during the marine start up programs and the biz went to his son so all that marine start up went away and basically was shelfed for good.

With that said Moroso currently wants to get its feet wet again in the marine side of the coin. So basically this is where I have fallen in with them. Persay Moroso Marine. This past summer I was the first one to get Moroso s brand new designed Dry sump oiling system that went into Team Woodys Race Boat. Yes that was a complete newly designed dry sump from Moroso and what a better way to test it than in marine app.

Anyways long story -- as it is no secret Moroso makes marine spark plug wires for me exclusively that took off in June 2019. These wire sets are not out of the auto side - not one set. For one I take new and fairly new plus used spark plug wire sets and send them off to Moroso inwhich they actually break down the oem and aftermarket wire sets that I personally sent in. Again all from Marine engines. They -- Moroso and myself discuss the good, the bad and the ugly as how to improve upon them all the way around to have better performing spark plug wire sets.

So for 2020 I totally wanted better sleeving for HEAT and GAS FUMES and emissions that happen in the engine compartment of marine apps. Plus I wanted the looks improved upon per what Moroso sleeving was using since day one.

Some other facts, Moroso is one of 3 companies ONLY that actually make all their own wire in HOUSE -- in the USA and including all the inner core wires. All other spark plug wire people buy from one of those 3 to make their own wires then of course put their name on it.. But then you have companies like MSD in which are made in China and Mercruiser spark plug wires are made in Mexico. All Mercruiser spark plug wires are made in Mexico and all are only 7 mm in diameter, this does not offer as much insulation layers for longevity in marine apps plus each wire is is very high in ohms per ft.

With that said I will have the complete marine line exclusively to offer thru Moroso per how I want them done and tested. First on the list was from day one was EMI and RFI suppression. One of the big issues to vastly reduce all that is with crimp at the connector to wire. Also the boot quality and its structure also how the wire is made. Next is notice the heat shrink at the boot and wire itself. All this helps and provides a better quality wire and better performing wire especially for todays EFI and ignition components.

So my questions are --- should I leave the wires plain with just the color sleeves or come up with something on the sleeves ( wording - logos or ?? ). Also keep in mind I can basically offer 8 different colors of the sleeving. So what colors should I offer -- Blue like I have in the pics - I take it red and black for 2 other colors to start out with -- what else ? .Feedback would help vastly. THANKS

Red, blue or black would pretty much cover it for me . They look good and I like the abrasion protection. Have you got an idea on pricing yet? I wouldn't care about logo as long as not big print . You could do like hardin and have your name on them since it is your baby.

Hi, John. For 700sci application, the wires are hidden when viewing the bilge. Therefore, I feel some "labeling" on the insulation itself is not good value. However, "Moroso" molded in to the boot would be nice, from a grip standpoint.

Let me know when they are available.

I’d be in for 2 sets, black or blue. Let us know when they’re available

I like the colored ones with the numbers DUI ignitions used to do them as well and I have them on one of my harleys.

Definitely have an identifying name and/or logo, and/or phone # on them. If the boat has a new owner, or another shop is working on them, they know where/how to get the replacement for them.

Thanks, I ll update but for today ---------

So today I took a sample piece of the sleeving - cut a piece off - One inch long and cooked it in a broiler for 60 mins at 400 degrees. Pulled it out and it was perfect and not even hot within 5 seconds. I could grab the sleeve completely and hold it between my fingers as it felt like it was never heated up.

. The company that makes the sleeving claims its good for heat up to 1200 degrees. So of course I am question marking that. I do not have anything to test up those temps. Anyways I put it back in the broiler for 15 mins at 450 degrees and it still looks and feels perfect. I am impressed with the sleeve for holding up to heat.. I am totally satisfied and impressed for heat protection using this exact sleeving.

60 mins straight https://cimg3.ibsrv.net/gimg/www.off...973c503a67.jpg
at 400 degrees I could not even touch the glass on the broiler it was really hot

Pricing is not really determine yet or should say not set in stone. I will have 3 different versions of the spark plug wires for all Merc Racing engines and the 496 s and custom engines. Also will be covering all black production side engines including Volvo penta and OMC. Outboard apps will be down the road.

350 OHM per Ft -- 8 mm diameter - Black wire NON sleeved Better than OEM replacement SPW set. Price is very affordable shipped prob close to 110 to 125 per set. discounts on multiple sets.

40 OHM per Ft - High performance SPW set -- what you see in pics here. -- 8 mm diameter - colored fully sleeved and heat shrinked boots. Price not set yet in stone but in the range of 175 to 195 shipped. The sleeving is not cheap. NO BS

3 rd wire set is in the making but having them affordable might be the issue ???

The wires do look very nice. I just don't see the need for heat protection for a boat engine. The temps the wires see are maybe 25% of what of they are in an automotive application.
Abrasion protection, I understand there is some need. My plug wires are generally pretty secure though and never had any issues. Also, are there some plug wire holder/separators that will fit over the shielding??

we have all plastic wire separators from all different colors to fit all different size SP wires, Here is on sample pic below for the non sleeved 8 mm wires. And all thru moroso USA. Again there is all sizes and colors for the plastic SP wire separators.

I want to keep all USA parts one is if any issues arise much better to resolve any of that dealing with home manu s. Also the communication is by far better so less chances of things going wrong. Next is I am so tired of the poor quality marine parts that come straight out of the box - all CHINA and Mexico made. Not saying that all USA made products do not have issues,

Next is you do not want to use metal SP wire separators - one is metal is conductive, also metal is corrosive - also metal can add to harmonics and vibrations. Metal is heavier. Also anything that carries electrical paths - you want to be very stable and no vibrations if all possible. This is very true for ECM s as well, and ignition systems - including SP wire. You do not want SP wires moving around all the time while the engine is running especially of they are close to sensors and or those wires / connectors.

. This separators from Moroso are all plastic and they agree with my logic as well about SP wire separators,

Maybe I can see if I can get one of the Moroso guys up here to answer some questions if that helps whom ever. even if its about oiling or even cool stuff they have done for race teams.

I think that would be cool for the site and all of us.

I agree with Griff about the heat issue but the abrasion protection if a definite plus.
I’m in for a couple sets when they’re available.

Just adding some thoughts as how I am looking at this and the reasons why - IMO the sleeving makes the wires look better and the colors seem more vibrant plus will not dull over time. Next my thoughts are -- how many boaters have really overheated their marines engines ? I see this a lot especially with mainstream boat owners - or how many sucked up a bunch of crap from the waters and one tube or more of CMI headers is running super hot ? Or even plugged up a sea strainer to cause an over heat ? Comparing to the auto side - I can not even remember the last time I seen an overheated car on the side of the road and we prob have 2 million autos running around here everyday 7 days a week.

Next is all electronics hate heat - when you add heat its causes electronic resistance - that in return causes increase in OHMs thru wires and circuits and sensors and so on - the sleeving keeps the wires cooler at all times to help with that.

Keep in mind 40 ohms per ft wires and I am working on even lower OHMs for wires. Also rubber degrades from heat over time as any increase temps from whatever heat source will dry out the compounds.. The sleeves will only add longevity to the wires.

The marine engines with cat exhaust run at 800 degrees around the cat and air space within the exhaust / risers - it has to build that amount of heat to operate correctly. When the impeller sheds - trust me the wires can blister. This is another reason why I am testing against heat.

When you see wires like this - These have been way over due. Volvo wires suffer at the boots to cap and start down the wire itself. Just like old tires that UV caused the degrading of rubber and the brownish discolor. everyone has seen that with boat trailer tires down the road. ( the brown discoloring on the walls of the tires ). The same with Volvo wires..

These wirers and boots were hard as a rock and the engine ran very poor. New cap and rotor and spark plug wires and plugs all good to go ran like a top as it should.. Pic below

and the reason why you OHM test wires but you need to know the specs of the OHMs per ft of the wires you have installed to see if they are within the specs. like I said more volvo wires and boots so common -- pics below and 2 wires were OL, ONLY 309 hours on the engine scan.https://cimg8.ibsrv.net/gimg/www.off...8011612fba.jpg
. this only had 309 hours on it

Thanks for the answers and pics

Amongst other things, Big plug gaps kill ignition parts. Right 496 owners ? :)

"Moroso Performance Marine by Boats Unlimited" or "Performance Marine by Boats Unlimited" gets my vote.

When I first read this post I did not notice that the sleeves are different than my regular car app Moroso Ultra 40's I have and these look nicer for sure. Had these been available when I needed mine I would have bought them in a heartbeat since they would also fit better than the car versions I now have.

Long story but BUP was a great help in figuring out that I had bought the wrong wires for my app the first time from Summit. Totally my fail...glad it came up in random conversation. Had I been able to buy them from him at the time I would have had the right wires to begin with. Essentially I have flushed two sets of wires worth of money down the drain. Moral of the story don't assume because they are "BBC" wires that they are made for boat applications. Lol

I like the strands of color in the woven loom. Adds some subtle eye candy. I think having the cylinder numbers somewhere on the boots or loom would be cool.

Blue or black and some kind of grip on the caps for easy removal and install. I also agree cylinder number is a big help. In for 2 sets 600SCI.

the spark plug wire numbers per cylinder are on both ends also in the pics above you can see them around the wire itself. Also for the 496 apps there is 4 wires shorter than the other 4. -- so with that said there is 4 wires the same length and the other 4 wires are the same length.

Blue, Red, and Black should cover your colors I think. Tough call on the logo, it would be nice to have a name so you can find more when you forget where you got them!

And thanks BUP for all your help with keeping us running here on OSO, You have helped me out just by my reading of your responses to others folks questions. Not many are experts on the 496!
