2003 Bayliner 4.3 Mercruiser I/O

[Faerbairn]

What fluids should I change for a full service? My last boat was a 4.3L OMC Cobra and it had special ways to fill the outdrive. Is this 4.3 Merc similar?

Thanks

engine oil/filter

drive gear lube.

remove bottom plug in the bullet, then the top vent pulg and drain old lube
fill drive through bottom drain plug hole until lube reaches top vent plug hole
insert top vent plug with a new plug gasket
remove fill from lower plug hole
install lower plug with a new gasket
run motor on muffs up to temp, check and fill lube monitor if needed

Head up to the Adults only sticky at the top of the forum. There are service manuals, owners manuals, and more information than you can imagine on Mercruiser.
