Props for Sunbird SWL 203

[Andrik]

I have changed motor from Evinrude Ocean Pro 175 to 150 on my Sunbird. The prop on the 175 was a Raker 14 1/2 x 20, the prop on the 150 is an ordinary 14 1/2 x 21+. Which one will be best for my Sunbird SWL 203? I have noe experience on this.

Thanks. But can anyone tell me how to loosen the Raker prop? Do I need a special tool? It seems not to be mounted mounted with a splitpin. Plese see attached picture.

Ayuh,.... That's a prop lock nut, much like those on fancy car wheels,....

Ya need the "Key" piece to unscrew it,....

 

[Andrik]

Ok, thanks. Do you know where I can get it?

 

[Bondo]

Ayuh,.... If yer lucky it's stuffed into a storage spot somewhere in the boat,....

 

[Andrik]

Ok, I`ll see what I can find....
