Learned something new, didn't know you could get the Pro XS 115 with a Command Thrust gearcase. But now I know :-) By the way, WOT for this motor is 5300-6300 rpm.
Yeah mine has the command thrust as well (2019). HOWEVER…. I’m very concerned. I’m pushing around 6,800-7,000 rpm at WOT and 45mph. I’m currently running the tempest 21p stainless prop from the factory. I do believe I’ll have to go up to a 23p. It goes in for its service tomorrow, I’m going to double check with the dealer.
@@mcplutt soooo here’s the story, I noticed I was pushing 7k the other day when I was running back to the ramp getting away from a storm. I thought to my self that isn’t good.. no rev limiter was hit.. when I got home I checked my owners manual and realized what I thought was accurate…. That’s not good to be running 7k…. So yeah it’s going on the shop tomorrow to be checked out 🤷♂️
@@PaulsOutdoorAcademy thanks for always answering my questions! My issue, that other folks with a 115 pro xs seem to have, is odd. Starts great, idles great, but runs erratic getting on plane 3500-5000 rpm. It sounds like it’s either cavitation from the prop slipping, causing the motor to rev up, then down, but it also sounds like it’s a fuel issue. I’m going to replace the fuel filters, spark plugs, and bore sleeve. If that doesn’t fix it, I’m at a loss
@jakewyler1945 you are welcome. I enjoy trying to help people. I wonder if by any chance you might have a little water in your fuel? Did the boat sit for a while during off season? Was the fuel left in it just a little or full tank? Was it 100% gas or methanol mix? Did it have a fuel stabilizer in it? You could add a fuel treatment to it now and see if that helps at all. You could try running the fuel level way down and then fill. Back up and see if that helps. If you replace the inline fuel rail filter, it would be a good time to check the fuel injectors. Make sure all connections are tight. You can even take a 12 volt source and make them open and close long enough to spray carb cleaner in them. I think they only have a positive and negative connection. It could be sooooooo many things and is trial and error. When you put plugs in I would definitely check the gap.
but you are aware that the aluminum properller will make the consumtion grow and decrease your top speed.. it's a two edged sword. but I got the rationale behind your change, but wouldnt it be easier to lift your trim while sailing shallow waters ? anyway... would you mind telling me what your properller is ? the numbers printed on it, please.
It is 48-8M0151382. There is an override on my trim and if you get over a certain rpm the trim disengages to keep the prop in the water. In skinny water it is scary when it does that 😎
thanks for the reply, I understand your motive now. I have a 100HP but the pitch of my propeller is 17. but I guess your engine has not only more power and topsteep but also some extra RPMs over mine. unfortunately mercury brazil doesn't sell ProXS here yet.
I think the ones with the gray lower end have the command thrust option. The ones that are black do not have that option. If you search command thrust for mercury motors I think it explains it pretty well. Thank you for your comment
Do you know what size that tab washer is? It’s totally different from the factory one. I’m trying to order one but some say 3 and some say 4 on the size. I have the 2020 115 pro xs
That is amazing..... Dang I need one... I may try to find a used one, I don't know. I was an observer in an MLF fishing event this past weekend and the boater had a 19 foot Caymas with a 225 Merc and it had a 23 pitch, 4 blade prop. That thing was rather terrifying in terms of how much power it had. It could launch you from zero to crap your pants in about 5 seconds. :) Thank you for letting me know, and I definitely hope to do that soon.
I am only getting about 45 out of the boat, unless I push the motor over the 6200 recommended Max RPM. I want to get a 23 and try it. Thank you for your comments. :)
Dont know if anyone gives a shit but if you're bored like me during the covid times then you can watch all of the new series on InstaFlixxer. Have been watching with my brother for the last couple of weeks =)
@@ronaldcogar8672 I never did. I can't justify the cost of one right now. I had my 21 completely reconditioned and balanced, and it is running smooth. I am still stuck at about 43-45 without going over the RPM limit. I will try to purchase a 23 maybe summer of 2022?? who knows. I will create a new video if I do. :)
I haven’t read any comments yet and I’ll tell you you’ll notice aloooooot of deference lol… First off with a aluminum prop and the crazy amount of flex the 115’s going to put on it, you went the wrong way with your pitch selection… Anything typically over a 90hp the performance of a aluminum in non existent.. It’ll go, but that’s about it as far as performance.. Really shouldn’t even use the word performance in the same sentence as aluminum 😂honestly… That motor at full throttle will change the pitch (depending on load) up to 5 pitches and sometimes more simply from flex… Stick one on a 250 or something like that and it’ll literally straighten the ears almost flat and fall off pad, especially in a tight turn… Buuuuuut for you just easing around and not running much and definitely not concerned with performance a aluminum would definitely get the job done considering you didn’t have to make a run of any kinda distance
Thank you Todd, for the comments. I was trying to ultimately get up on plane as fast as possible in order to accommodate the shallow water at Norris. I lost about 5 MPH, which was totally fine with me. What I gained was the ability to get that thing planed out QUICK. hahahahah. :) I am really wanting to get a 22 or 23 SS Prop to try. I think I could get close to 50 MPH with one of those. :)
Honest to goodness I do not remember. That being said, when I switched it back over to the SS prop, it came off just fine. I would imagine some type of lithium grease
The 19? Yes totally agree and did you see I was saying that was on purpose for fishing in shallow water where you need to get on plane extremely fast? I only used it for that or a backup. Ultimately I want to put a 22 on it. Thank you for the comments
The PROP? the skeg on that lower housing (racing housing....) you could buy a room full of SS props if a rock kills it. Rent a canoe and leave that high dollar stuff home....
Yes, I know. I spent a bit of time with the motor way up until I learned a good route. You are right, a canoe is great. have room to walk around and be comfortable was nice though. :)
Great video. Really liked your style of making it. Navigation routes are discovered because a brave man dared to try them. Thanks for sharing👍
Thank you so much! I totally agree. Someone tried it FIRST... :) I just had to learn the hard way. hahahahah. Thank you for your comments.
Sir you are priceless in your teachings.
Thank you very much for this compliment, it means a lot to me to be able to help people do things like this! 😀
Very good teaching skills! Nice explanation of a tricky job.
Thank you very much!
You need to go up in pitch for both props. 23 pitch for the SS and 21 pitch for the Aluminum.
I am debating the 23 for sure. Thank you for the info
Learned something new, didn't know you could get the Pro XS 115 with a Command Thrust gearcase. But now I know :-)
By the way, WOT for this motor is 5300-6300 rpm.
Thank you! I don't if they offered CT before 2019, but it came standard with my motor. So far, I love it. :)

@@EricRomines Why are you pushing 7,000 rpm when you know the max. is 6,300 rpm? And isn't there an rpm limiter on every motor?
@@mcplutt soooo here’s the story, I noticed I was pushing 7k the other day when I was running back to the ramp getting away from a storm.

@@EricRomines Mine is the same. I can't run it wide open. Debating on going to 22 pitch.
It’s actually called a doohickey. You have to beat it firmly in the thingamajig.
doohickeys are hard to find. HAHAHAH Thank you!!!!
Isn’t there a plastic bore sleeve that’s supposed to go behind the prop to prevent exhaust from surrounding the prop and causing cavitation?
There absolutely is. I didn’t know it at the time but the tabs were missing on mine. I have since replaced it with a new one 😎

Hello. What is the difference between the Mercury 115 PRO XS with a black bottom and a silver bottom?
I think the ones with the gray lower end have the command thrust option. The ones that are black do not have that option. If you search command thrust for mercury motors I think it explains it pretty well. Thank you for your comment

I will measure it and send to you. Do u mean the original or the one from Solas?
@@PaulsOutdoorAcademy the Solas preferably, and thanks for the reply.
I found one that fits buddy, no need to go through the trouble now. Thanks for the video though.
U r totally welcome. Let me know if you have questions! 😎
I put a 21 pitch lazer 2 on my boat I got 53 mph 2 people & fishing gear

Ottimo motore potente...
115 is powerful for aluminum boats, but it seems limited to around 43 MPH.
That’s a huge prop, what’s your top end speed at what rpm with that?
I am only getting about 45 out of the boat, unless I push the motor over the 6200 recommended Max RPM. I want to get a 23 and try it. Thank you for your comments. :)

what kind of grease are you using
Honest to goodness I do not remember. That being said, when I switched it back over to the SS prop, it came off just fine. I would imagine some type of lithium grease
I looked it up. Looks like a Lithium based, 2 4 c. Quicksilver. I will use that when I get the time to take the prop off again.
What is the diameter of the prop pass 23?
Looks like the 23 pitch Tempest SS Prop is 14 5/8" Diameter. :)
Jeez. Very underpropped there

我的是水星 115hp，原厂配的是铝制的钱，我刚订购了一个，Mercury - Veng 14x19 rh - 48-8M0151407 也不知道速度去到多少，我也是观看 youtube 其它的博主他也是用 14x19p 感觉不错，就订购了一个，4 月中旬下海试试，看 rpm 去到多少，速度多少😅
Thank you
