Mo-Powah SX190 Flame Arrestor removal


Mine is spinning at 7850 but there no real top speed gains it appears for me but I'm assuming both your engines will hit this with it removed.
 
Can this be done to an SX210 with the 1050cc engines?

I hit 52 last weekend , it be cool to get 53-54 !!!! , prob just a pipe dream , but it would be cool
 
I'd be willing to bet that @swatski engine remap would get you 55 mph but its a little pricey for twin engine boats.

Yes. However you are unlikely to see much gain, even with velocity stacks. MR1s seem well vented from factory.

What I have learned, with only Stage 2 tunes (which I run) you get more torque and greatly improved power curve. But for substantial top gains you have to rev the engine much higher with additional mods. Need more than Stage 2 reflash to get to 55mph, I think. Keep in mind 2-3mph gain is huge.

I did this in my old sx230 ho and my current 242 Ls. In Both instances I saw absolutely no change/increase in rpm. It may work for others, I think it's altitude dependent, but the only change I saw was what I got back after paying $40 to $50 per manifold mod/ set of velocity stacks.

I think the idea is to get an aftermarket metal mesh air filter to act as a flame arrestor once the stock flame arrestor(s) are removed.

@Ronnie I'm just curious - with the 1.8 engines where you already on limiter before ribbon delete?
 
Yes, I was at the rev limit on both boats before the mods. That is, 10,200 on the SX and right around 7,800 on the LS. Most of my boating is done st sealevel.
 
I was able to remove the ribbon by grabbing the edge of the rubber ring with some pliers from opposite sides and it slid straight out. Its in a bag in the boat incase I ever need to return it back in there. I guess Ill report back on findings after we get back out on the water. I'm real curious if i'll be able to feel or hear any difference.
 
When do you think you will get it back on the water? I will try the same ribbon delete on y 2012 SX190, however I will not get on the water until, at best, first of June. Curious about how much more low end, out of the hole punch this adds. I live at altitude and could use some more help out of the hole.

Ideally I will run my boat doing a Before and After type seat of the pants testing. Or heck, I may just remove it and go.

Do it. You will love it, a complete no-brainer.

Because the Masters tournament is coming to town and our home is rented to a golfer we won't be back on the boat until mid April. I will report back how it feels. Boat tops at 42 MPH on a calm lake with 4 of us aboard and the bimini stowed, so ill know for sure if we get anything out of it.
 
LOL. That's the one thing I don't miss about living in Augusta...

Mr-1 intakes are simply too large for their own good. I got the rubber velocity stacks and no filter. My thought was that the rubber due to suction may decrease the bore slightly increasing the velocity of the air but really it would be very little. Until someone gets a wideband 02 sensor on a mr-1 there is very little to do to them.

The 1.8 seems very promising and if you are in the market for performance, just follow these line of threads!

Did you get a chance to test your boat after the ribbon delete? My 2016 AR190 tops off at 42MPH (Factory Speedo) and 7300RPM with two people on board, half tank. I want to try it myself. I'm at Lake Hopatcong, NJ, Elevation 950ft.
 
Did the same couple weeks ago - the ribbon delete on my 2012 SX190, following a write up on the other site.

Huge difference - worked out great!

can you link? was looking for a DIY
