I'm not sure where to start, but,
I have a 26' Formula Thunderbird 1977, 454's TR drives.
The props are alum. 20" diameter 15p. I know this isn't the right setup, but it's what I got,and have to deal with.
What would you suggest I try?
I really dont know anything about props, but have been reading everything here and am starting to get a basic understanding.
Any and all help will sure be appreciated.
Thanks, Larry

Your boat will do well with stainless steel 3 blade props. We can start with some test Mirage Plus propellers. Call us and we can make arrangements.

Brett,
Thank you for your quick response.
I'm calling you now. Had a feelin you'd have the answer from all the post i'v been reading.

Larry

well. They launched her, so, I can't verify the shaft dimention or spline.
But Mary did write down a # on the prop.
B ? 48 18611 A4? 15P
And I got my old TRS drives back w/props,
they are Quicksilver 48 13704 A40 23P

The fist number is a Bravo 2 propeller and the second is a Mirage propeller.

Thank you Sir,
So, I need Bravo II props for these TR drives ??
Think you got anything that would work ? Used ?
Or, what would you suggest I should be lookin for ?
Thanks again.
Larry
