Please advise - 305 to 350 Swap

[Bufford Evans]

Hello everyone .
I'm hoping someone can point me in the right direction.
I havery a bayliner skagit that I'm trying to repower
the drive is i bieve a Volvo Penta aquamatic 280 duoprop
and ive located Volvo Penta 570 350 chevy motor .
The motor that im replacing is a 305 chevy ...
I'm almost certain that the outdrive is the 280 because the boat came with shop manuals for the 280 etc etc the serial number off of the outdrive is PZ NR 2888664 B but I cannot find ANYTHING online with that number when I google search .I'm hoping these 2 systems will button right on up .Any advise or direction is much appreciated

It should not be a problem, re use the engine mounts from the 305 on the 350 since they were adjusted already. Are the engine harnesses the same where it connects to the boat harness?
Does the replacement engine have the PDS housing attached or do you have to separate it at the rear of the engine?
