Hey guys, im still doing my homework and you all are a great help, i have been shopping for upgrades for my 19' Bayliner, from a AQ131A/275 od to a ???/. I have found a AQ170A/270 od. Do any of you know the HP of this engine and would it be a good swap ?? I have also found a 4.3 crate motor and a 290 od. Not sure if they will bolt together and what adaptors and plates i will need, while the 170/270 set up is complete.<br />Any thoughts >????<br />As always, Thanks much
