Hi! Welcome to the madhouse!
I'm at work at the mo, so can't enlarge the pics too much -hence 2 Qs - How big is the boat (I guess 6.5-ish m?) and how many Gee Gees is that engne? - I guess somewhrere round the 130 mark from the shape?
Re./ the transom height / engine leg length- I reckon that hull was set up for twins based on the fact the "lip" is missing in the locations I would expect you would want to park a pair of engines. Now, this is where the measurements get fun:
Measure the depth of the transom at the midpoint of those two cutouts - I'll bet the depth is 25 inches.
I'll need to hand you over to the tank carrying brigade (I don't dive!) but beofre you start sawing the transom around - and assuming that is a 6.5m or bigger hull & 130 odd HP engine, do you actually want to be looking for a twin for it? (Although they are not a young design so that may be a bit more difficult than it looks unless you don't mind resuscitating engines!)
And before the "twin vs single debate starts again - if the transom is set up for a pair, why @rse around with it & risk a leak / rotten transom? Especially as those Clamshell type engines were remarkably light for their HP.
