There is a 535 with a big engine on a trailer in the boatyard at Milford, and I am hoping to be down there this weekend.
I will get some approx measurements of the distance from transom to axle to winch post on their trailer for you, if it looks well set up.
I will measure mine too. Although an F4 is substantially heavier than a 535, the balance point should be at roughly the same position as they are the same length.

Yes, if you can, bring the boat forward on the trailer. The part the bow comes up to (has a rubber stop) is usually adjustable. I was advised to also align the winch with the eyelet on the boat.
The other benefit is the stern will be closer to the back of the trailer.
