Fluid capacities and weights

[myoung84]

I tried searching but could not find what I was looking for. I am about to winterize my 05 Tahoe and need to know what the engine oil and outdrive gear oil fluid capacities are and the recommended fluid weights.. It's the carb'd 190HP 4.3L with Alpha 1 outdrive. I didn't save the info from when I did this last year and cannot find it again...

Thanks!

Ayuh,... The drive uses Just over a Qt. of 75W-90 syn-oil... Merc sells their own of course...

The motor probably holds 5 Qt.s but I drump in 4, fire it up, check for leaks, then top it off to the Full line on the dipstick, with the motor in the same attitude as it sets in the water....

You will find that information in the OEM service manual, including how to fill the drive and gear lube reservoir properly. Get 2 quarts of gear lube, while the drive holds just over a quart, you then have the gear lube reservoir on the engine to fill.
Best to use the Mercruiser Hi Performance gear lube in the drive (Green in color).

Thanks for the replies. I bought 5 quarts of 25W-40 Quicksilver oil and 2 quarts of High Performance Quicksilver gear lube at Academy last night. I had to go to O'Reilly's to buy the filter (Wix) since no one had the Quicksilver filters in stock. I also drained the water in the engine and filled with the pink antifreeze and poured some fuel stabilizer in the gas tank. I will change the fuel filter next spring and she will be ready to go!

Has anyone converted to Amsoil on here? I am thinking to swithcing next year. I use Amsoil in my vehicles and would like to use in the boat. I have a local dealer that gives me pretty good pricing. The Amsoil site recommends either 10w-30 or 10w-40, what would be better? It's always above at least 80 degrees when I run the boat, but typically it's about 90-100+ degrees.

Unless you run the engine AFTER adding fuel stabilizer you just skipped the most important step in the process which is to "protect the fuel system". All you did was stabilize the fuel. The fuel that is in the lines and carb can turn to gunk which is the main reason for fuel stabilization.

I left out a lot of the details, but yes, I did run the engine for about 15 minutes after pouring in the fuel stabilizer.
