Do you have power steering ?

Nope. I read I can adjust the tab on the drive above the propeller to adjust for it.

Considerable difference between a CVX and 179 tri-hull. Not a fair comparison if only looking at props. The 23 that cames on mine was not a modern prop, more of a mouse ear. I ended up using an aluminum prop that gave decent results. It was a great boat, but if you're performance oriented, the four cylinder will only go so fast.

That's great info! I went to bolt it on and it hits the anode trim tab. Looks like I need one that clears. Anyone have one?

Your local Merc dealer should have one for about $20.

I've modified torque tabs to clear, IO's with power steering can use smooth tabs for cathodic protection. Figure 1/4" clearance with SS props, and closer to half if using aluminum props. Never hurt to just try it without to see how bad the torque steer is. Every bit of trial and error to get them set just right.

Ok, what do I need to bolt the end on? My aluminum prop has a removable hub that slips on after putting prop on with castle for the retainer to install over. The Stainless prop has a pressed in hub with rubber around it and shows splines when installed, and I only have the retainer and nut that would go on. Do I need a castle spacer or something?

Yes .. use "Tab Washer" and make sure you have "Thurst Washer" installed and clearance.

I have all of this but there are still splines above the hub when its on the thrust washer. My aluminum prop has an insert int the hub that installs after installing the prop.

I'd guess no Gregg, in the GC world, I've only seen it on V8's. The exception is Brandon who added it to his 4-cylinder craft.

Demian5 .. Wrong thrust washer ?
I'm not sure what your saying ?

Mike .. All my Merc O/B's and Mercruiser's had tab washer that locks nut in place.
Or are you talking about thrust washer ?

Maybe Dave P. can help ..

You don't have one of these in there ?

Jason · « **Reply #33 on:** October 25, 2019, 07:00:42 AM »

You need everything shown in Gregg's picture above.

If you get your trim tab dialed in correctly you should have almost no torque steer. My 4 year olds can drive my CV16SS with a 23P Laser II and it does not have power steering.

Post a picture of your tab so I can use it as a starting point and understand whats happening. Thanks!

Been so long since I've owned a non Flo-Torq prop, that I forgot about that part.

Here is my trim tab angle looking up from bottom. Also my notch. Not the prettiest thing but it works!

I got the brass castle washer, amd I supposed to have a large star washer that goes between the castle nut and the prop body?
