Love the idea about resting oil in hot water. I place mine on the driveway while draining and flipped it over the get the other side nice and hot. (In Louisiana). One other pro tip is to place the pump on the top vent air threads and pump out the oil out faster using pump without anything attached. Good and quick vid, the way i like it

Thx - I just paid $375 for an impeller change. (And another $75 for lower unit oil change) I just hit 600 hours so thought it's time (I had one installed at 300 hours.)
After watching your vid, I think I'll be tackling this myself.

You should all be aware that both the vent & Drain screw have gaskets. It is important to make sure these are in tact. I would suggest every year to just go ahead and replace both screws and gaskets since they come together and are maybe 5$

Rad video ! I just got a wellctaft 210 excel with the mercruiser alpha one ! It’s pretty fun and your videos are helpful. Thank you

Just as a quick addendum, I followed this helpful guide, but didn't fill up the Drive Lube reservoir in the engine compartment. This was tripping an alarm after starting up the boat and we couldn't figure out why. Make sure to fill up the reservoir after draining and replacing gear Lube to prevent this from happening.

Very helpful. Just bought my first boat and have been watching your vids.

As far as a Bravo you have to pull the prop off, the drain is in the prop shaft carrier. Don't forget to grease the prop shaft splines with marine grease and check for fishing line.

Thanks. I’ve done that b4 but was an excellent refresher. Thanks again!

Overall, good vid! One suggestion is to remove the drain plug before you remove the vent plug at top. By removing the vent plug last, it keeps all the lube from rushing out as quickly when you remove the drain plug and makes less of a mess. Once your hands are no longer under the outdrive, remove the vent plug and it will flow quickly.

Thanks for this video. I heated up the oil in a bath and it was fast.!

Wow your oil looks so clean I thought I was at the end of the video

Some pro tips...remove the vent screw AFTER removing the lower drain screw at the bottom. This prevents the oil from gushing out the vent as well as gushing out the bottom. Also make sure the cap on the gear oil reservoir is off so the oil drains more quickly. Once the oil drains out of the lower unit, screw the vent cap in about half way. This will still allow the gear oil to gush out the vent once full, but minimizes the mess as the screw is already halfway in place. Newer Mercruiser engines take about 1.5 qts of SAE 90 high-performance gear oil, including topping off the oil in the gear oil reservoir.
