I did it myself but unfortunately did not take any pics during the process. I was trying to get it done quick while the boat was off the trailer and sitting unattended at the ramps dock.
First I removed the boatbuddy and with a grinder and cutting wheel cut 2" off the top of the two metal plates on top the bow stop along with the rear corners. Then ground the edges down with a grinding wheel and re-drilled the holes for the roller axial. Then painted and installed the roller, all in less than 10 min. I bought the roller at Bass Pro. A rough drawing is below along with finished product.
The other thing I had to do was lower my winch because the handle hit the bow of the boat, but that's going to depend on your winch and its factory installed location, just keep that in mind.
Jerry at Boatmate offered to do the mod at no charge but it was easier for me to do it myself rather than drive 4 hours each way to drop it off and another 4 each way to pick it up.
Another reason I did the mod was the two front bunks, and 1/2 of the middle bunks, were 2" from touching the boat. So, all the weight from the front half of the boat was resting on the boatbuddy which destroyed it along with messing up the gelcoat below the bow. If you do the mod yourself just be aware of all your measurements so everything will fit correctly. Others trailers could have different dimensions, this is just what worked for mine...my disclaimer.
Hope this helps, Steve
