I’ve eliminated all but a small amount of cavitation when turning tight corners and occasionally at take off. I have all 3 spacers installed and was wondering if anyone has installed more than 3. Is this an option and would it get rid of the last bit of cavitation I’m experiencing? I appreciate your thoughts and insight.

The 2019 pumps are a bit different so I don’t know for sure, but may need a longer bolt and then the tip of the cone may start sticking out of the Venturi nozzle, probably not ideal.

Since I have a 19 190 and cobra fins, I have been following your Ribbon Delete and Lucky 13 upgrade. Seems like your pretty happy with both with less cavitation and better low and mid range response. Have you had a chance to test the top end?

I’m very happy with the results of the few mods I’ve done. I only lost about 3-4 mph at wot after installing the L13 cone. I didn’t mind since it gave me more pull on the low end and fixed the bleeding off of speed in the turns, which was my main reason for doing it. However, after I did the ribbon delete just recently, it increased my rpm’s about 200 which gave me my 3-4 mph back plus some. Overall a very good outcome. I’m just being a little picky now to see if I can eliminate 100% of the cavitation but really, it’s very minimal and doesn’t really affect my overall performance. I wouldn’t hesitate to encourage anyone with the 2019 190 to do any or all of these mods.
