Transom Assembly question
 

Looking for opinions on TAs
Changing out transom assemblys while motors out. Trying to decide on Seacore or HP. Has standard bravo TA now.
The boat :45 Excalibur 17-18k loaded, new engines 600ish hp, BIII 30p props, docked in brackish (mostly fresh) river, sees salt water weekly May-Sept., don't need trim senders have mechanicals.
HP might be overkill, Seacore are supposed to be better aluminum alloy and magnum strength.
Thanks
