I am a newer member and just picked up a 24 Excalibur for a winter project in the Syracuse area in NY does anyone recognize it or have any history?

the engine is currently being stroked to a 540cid hopefully to be pushing 700-750hp... does anyone have any info on whether the x dimension on the drive should be changed and if so how far?

is that a bravo drive?
24 pantera w/ b1 xdim should be around 17.5", so that should get you close.

No, I am sticking with the Trs and merc two trans which has been reworked with more clutch plates etc to hold the hp. Iv always had good luck with the trs so i figured may as well stick with it. Iv been told that raising the X dimension could give me more speed just dont want to go to far, figured somebody has done it with luck?

Saw that one for sale last year in Cicero... Good Luck with it...

She was a little rough... Replacing the transom now and converting it to a 496 with a bravo... Have any history on it?

nice project . i had a 79 24 with trs and changed it to bravo with a 750 hp blower motor . it did go faster but it had a lot more chinewalk i think you are making the right choice for this style boat. I now have a 1980 32 ft excalibur with twins and love it . It is great for the Lake of the ozarks. good luck with project .Kurt
