I unfortunately dinged both of my Volvo props last summer and now have an extra set of props and my son and I have first hand knowledge of how to remove and install the new forward drive props while standing in chest deep water under the boat lift!! My rebuilt props did give me the exact same top end as before the damage so I believe I have my local propeller shop.

Curious if you needed any extra tools? Special socket or something? I’m about to find out how much fun this is sadly after bending one of the front prop blades almost in half. Stumps!!

Appreciate any tips and tricks!

Hey TxS. Welcome to the CobaltChat forum. Sorry to hear about your prop woes. I have done the same and that feeling is not a good one.

Any pics of your prop blades? I bent both on my Volvo Penta duo prop many years ago.

I had the Volvo Prop wrench to take those props off. Here is an amazon link showing a pic.

Feel free to start an intro thread if you have time. We'd love to see pics of your Cobalt.

And again, welcome aboard mate!

No specialty tools, just hex wrenches and I’d recommend a torque wrench and follow the Volvo recommended torque settings. If you under tighten you will have a problem.

TXSurfer, do you have the Volvo Penta forward surf duo prop drive or the rear facing duoprop drive? The tools in my link are for a rear facing drive.

Picked up a bad ding on one of my props. F4 size. Any one know of a good place to buy a back set so I don’t lose down time during peak season to get repaired?

So what your saying your local prop guy can't buy or fix it this week? Myself I would call bblades.
