I have started cutting the rot out of this 17' tri-hull and would like to run stringers for a 4.3 instead of the mercruiser 140 i pulled out. I took the transom apart today and am thinking i should have sat a 4.3 in first to see where the new stringers will need to be. Have i messed up or is there some where i can find the measurement for stringers for a 4.3?

Find another boat with a 4.3 and measure.

The stringers will essentially be in the same place. The mounting will be somewhat different and wider.

I'll do that.

I am told the 140 and the 4.3 use the same bell housing. I take it the side motor mounts on the 4.3 are adjustable for alignment?
