Hey Sumner, do you know if those props will fit a 2008 Merc 4 cycle? Mercury apparently doesn't make extra props for the 4 HP anymore. I've been thinking the high thrust might get me to hull speed without being wide open.
I'd call onlineoutboards and ask them if this one would work:
......dia.........pitch.....blades..................................Tohatsu Part Number
......8.375 .......
6 ......... 3
(high thrust) (6hp SailPro model) 399B645121
I know you probably know that Tohatsu makes the small Mercury outboards, but I think there are a few differences. The 4,5 and 6 HP are all the same outboard, just a different carb.
They are who we got our Tohatsu outboards from.
If you don't have luck there I know of a place that might be able to re-pitch the prop. I had a prop for our Honda 8 HP re-pitch. If I remeber right it was about $100 total for the prop and to have it pitched to a lower pitch. They did a nice job. I can't remember the name of the place off hand, but it is in our records,
