Is it gonna be sitting to stern low for comfort and if so what do you think I should do to even it out
It depends on whether you are using the flooding hull or not. If you have it sealed up, I'd guess it would be OK. I have a 115 2-stroke Yamaha on the back and with the flooding hull it sits too low. Reseal in progress at the moment! My Yam weights 167kg and I don't have an A-frame or tanks at the back. My console is a bit further back than I'd like though.
From memory the max transom weight is 175kg (=385lb) so you should just be OK with the main engine. Add another 75lb and it might get a bit interesting. With your new Honda will you need the aux at all?
Turbodiesels point about overall handling is a good one as well.
Sounds like you've committed on the Honda though . . . !
