Trojan Boat Forum

I have a '75 as well with fire suppression that was professionally installed. I will check this weekend on the size and take photos of the locations for you.

I am with MCCOPS on this one. Your prop needs to be matched to your boat and engine combination. When the engine changes you will have to find the correct prop pitch to get max rpm. Check out this link. It has a ton of info on choosing the right prop. http://www.propfix.com/services_prop_education.php
