You cant set it manually, its electronically done by the computer so its always right. If you have a driveability problem suspect something else (fouled spark plugs, dirty injectors, clogged fuel filter, weak fuel pump, bad fuel pressure regulator, low compression, etc), but if you're certain its the timing then varify the crank and camshaft position sensors are both working correctly. Also check the timing chain, if its worn enough to jump time and your camshaft is improperly syncronized to the crankshaft it won't run well (if at all).

How do you set the timing on a 305 Chevy marine motor?
To set the timing on a 305 Chevy marine motor, first, ensure the engine is at operating temperature and turned off. Disconnect the timing connector to bypass the electronic control module, then use a timing light to check the timing mark on the harmonic balancer against the timing tab on the engine. Adjust the distributor by loosening the hold-down bolt and turning it until the timing light indicates the desired timing setting, typically around 8-12 degrees BTDC for a marine application. Finally, reconnect the timing connector and recheck the timing to ensure it remains accurate.
