Whats envolved with serviceing an outdrive? The boat is a 28 ft formula with a 305 chevy v8 and all the identifying decals are missing....plus I havent seen the boat yet,,,,, Helping out a relitive when I get there....Any advice and how toos are greatly appreciated.... Shifting between foreward and reverse seem to be stiff and Im thinking cable time? Boat is not in water, and not started in a few years...

If you want to service the outdrive - then the brand might be helpful. If you're talking about the engine itself, that's another matter... What's the goal here?

Formulas tend to have Mercruiser drives... Basic maintenance is limited to changing the fluids in the outdrive unit, checking the rubber bellows for deterioration, changing, if necessary, the water intake pump, checking the exhaust bellows for deterioration, checking the hydraulics for trim function, and changing the zinc anode for wear(assuming salt water usage). The engine itself is a chevy 305 - that requires the typical automotive maintenance - depending on age/model - points/plugs/condensor - checking exhaust manifolds for deterioration, carburator rebuild, starter problems (water is bad for this system), cleaning a fuel injection system.

If shifting is an issue, check the cable travel/ease... disconnect it and try it to see if the problem is in the transmission or the cables themselves..... easily done.

Its actually a volvo penta drive....275 and was not concerned with motor stuff....been a car mech for along time....new to this boat stuff....was mainly an outdrive query...but thanks....I see a drain screw for draining the outdrive....where do u fill it? is it in the engine compartment? ....or ontop of the drive somewhere? What weight oil? Sorry for the q's but the local boat shops arent kind about giving out info on stealing thier work away....And the manual was lost long ago....Cable was replaced about a year ago....but never put in water or even used since,,,,seems to be stiff and should the gears be easy manually without cable attached? seems like thier stiff too.........not easily moved....Gotta use some sort of water clamp devive on the outdrive if im gonna run this thing outa the water correct? dont wanna burn up the motor or water pump.... and its been a fresh water boat since new....

Should be two screws in the outdrive, one high, one low. You drain via the lower hole - and refill through the same one until lube comes out the top hole. You can find proper lubes at your marina/boat shop. You do need earmuff type water suppliers to run the engine in the driveway to keep your motor/water pump from burning up. Shift should be "minor tight" - but shiftable without using too much muscle power.
