1974 20 Ft CC SF transom

[fly4navy]

Just curious,

Has everyone who has repowered with a 4 stroke engine at 115 h.p. or above, gone ahead and raised the transom on their boat?
I have a new (to me) original 1974 20 ft. CC SF and am having installed a 115 h.p. E-TEC this week.
I just don't see how the low transom height of my vintage year Seacraft can handle the weight of a 4 stroke (particularly 140 h.p. and above) without really getting the waterline close to the top. I am not planing on raising my transom unless I run into a structural need to replace it.
Has this created an operational or safety issue for anyone? I assume the boat was designed the way it was, with this issue having been considered.

Thanks for any input.
