I would like some feedback regarding my Sedan Bridge. I have rebuilt the heads and carburetors (quadrajets), new plugs, on both engines (mercruiser 5.7 260hp) and installed a closed cooling system. Timed and adjusted to spec, the engines sound and run great and you can feel them pull hard.
The boat has half fuel and two persons onboard, with no crazy overloads anywhere (dozen beer in the fridge). The trim tabs are working and they were trimmed bow down. The engines wouldn't go over 3500 rpm as she was plowing trying to get on plane.
I took pictures of the props when on the hard, but can't find them so I am unsure if the previous owner installed something other than recommended by Sea Ray (16x15p). I'll get the diver to go and read what they are, as I'm in Mexico and I'm not going in to this marina water. This was the second time I have taken the boat out since buying it, as I have been working on it (waiting for parts), and busy with business.
My question is; what props do other same boat operators have installed, for their best performance?
What rpm should I expect at 10 knots attempting to plane with this boat?
