Lucky 13 ( L13 ) Anti-Cavitation Cone Install / 2016 AR240

[Huv1]

That's correct. Installed the sho/ho lucky 13 cone today on my 2019 190. Pretty easy. Make sure to swap grease and o ring. I was concerned that I tightened the Allen bolts too much. Added cobra fins as well. We'll test it out this weekend.

Thank you. Please let us know after your test this weekend on how she feels.

I’ve got the cone off ready to install the L13 when it arrives tomorrow. I noticed when I took the Venturi/bucket housing off there was a gasket seal around the rim. Did you put anything on that when you reassembled or does it need it? The original came off in a few spots when I pulled it off.

Tried it out today. Definitely helped hole shot but not sure about top speed. Only got around 37 mph but it was rough water and very windy. Previously got 42 mph top. Fins seemed to help with stearing but it does add a little more resistance. Hopefully the fins and cone didn't reduce top speed. I'd like to keep my top speed at 40+. Haven't tried any water sports yet.

sounds like you might need a few more runs to determine if it helped. Did you see my question above? Just curious if yours had the same gasket like material.

It did. I just used some silicone in place of it. Use gasket maker if you have it.

Not critical but gasket maker silicone or blue RV silicone can be used there.

The top RPM will be more informative to follow, along the top speed, is using the same impeller.
What was you top RPM before and after? If it is dropping too much need to take spacers off.

My top speed was 48 after all the mods on my 192 pushing 7800 RPMs. See sig for mods. You should always be above 40. Like @swatski said it all about the RPM. Let us know what it is.

I believe I'm around 7600 rpm if I remember correctly which is around where I was prior to the install. I really just need to test it out on calmer water. Which spacers would you take off first?

I believe the best way to prove a point is to go from one extreme to the other. Take them all out and see what you get then. You need to understand the best and worst condition you can get and then adjust accordingly. But, please take the boat out again before you do anything to record your readings. Then start experimenting.

The manual at least for my boat calls for Loctite anerobic gasket maker between the Venturi and the pump. I used the permatex version which seemed to work well. Permatex® Anaerobic Gasket Maker - Permatex

I run on my lake at about 151' elevation. Am I correct that there are no real adverse impacts with these boats until you get higher in elevation? The Lucky 13 cone arrived today and I'll be installing it tonight when I get home. Cobra fins were installed last night. Hopefully I'll be dropping it back in the water within the next couple evenings to see how it performs.

Did you have any trouble getting the fins on? The tip of my spring kept catching on the reverse bucket so I had to add an extra washer on the right side to space it out slightly further.

I didn’t have any issues. Nothing was catching.

Did you have to cut down the steering linkage bolt? I can’t get mine on without it hitting the spring in the cobra fin. I’m going to cut it but was curious if I am the only one.

The steering linkage bolt is supposed to be aimed down not up with the bolt head on top not the nylock nut. that is why I said to remove the fin and put the bolt back the correct way.

 

[Huv1]

Cobra fins and Lucky 13 cone installed. I had a little hiccup where I put the steering linkage bolt in upside down with the nut on the top but that is corrected and all is good. Hopefully I’ll get it in the water tomorrow night to see how it handles.

Went out on the water today to test out the cone. With all 3 spacers I'm at around 7600 rpm and top speed around 37 mph. When I removed all the spacers it took me down to 7500 with a top speed of 35.

Not sure why I'm experiencing a loss in top speed as I used to be able to run 40-42 WOT with a stock cone, ribbon delete and no fins. That was also prior to my 10 hour service (changed oil and filter, added grease to housing). I checked the oil level and I'm right between the high-low marks and I put the right amount of grease in the housing. Any thoughts on what is killing my top speed?

What were you top RPM before? Same impeller?
