TOPIC: Needed: 17P-19P 4-blade Merc Prop for '78 1400

I'd really like to find out what prop I'm going to need for the Fabuglas Commodore. I'm probably a week away from getting her wet again after a 4-year hiatus.
I'm pretty sure the 23P SS Laser II is too much prop for my hull, and don't want to lug the engine- even for "testing".

Props are pretty pricey to just buy and test. Especially in Stainless Steel.
I'm just looking for a used-prop... aluminum or SS, in good or better condition. I will purchase a new SS prop once I have it figured out.
Will pay shipping both ways (I can send you a pdf shipping label to print), and can pay-pal a deposit if you have concerns about it's return.

I have been boating on these lakes since 2001 and have never hit anything or damaged a prop... and would not test it in any unknown areas of the lake(s).
