Hey all,
I am in the middle of a repower of our Bertram 25 hard top. Pulled the twin inline 6/alphas and going with Merc 540 Magnum Bravo 4v with a Bravo 3 XR (possibly X) Drive.
Looking for guidance on what gear ratio ...possibly props if anyone has an idea.
The engine makes 440 HP at 4600 RPM and gobs of torque. (numbers may be understated by Merc).
Thoughts?
