Alright today on Repairs101 I’m going to help a friend out by changing the transmission fluid in his boat’s Borg-Warner Velvet Drive marine gear.
The Malibu Skier is a fairly common boat here and the Velvet Drive is definitely one of the most common marine gearboxes - anywhere.
By far the most common question I’m asked as a mechanic is what kind of oil to use. Velvet Drive transmissions will operate with any number of different fluids but use Dextron III for it’s resistance to oxidization and thermal degradation.
If you feel around underneath you’ll notice there’s no drain plug and even if there was you wouldn’t be able to get a tray underneath to collect the used oil.
Never drop the oil into the bilge of your boat. Use a suction pump and a recovery jug to collect the used oil for recycling.
Here you can see I forgot to bring a funnel with me so I just cut one out of the corner of a plastic bag.
If you don’t have the owner’s manual or access to the service manual and an internet search doesn’t yield the fluid capacity just pour slowly and check often.
The best part of being a marine mechanic is going out for sea trials.
After ten or fifteen minutes shut her down and check your levels again.
Alright thanks for watching and don’t forget to subscribe!
Probably worth mentioning the manual says that oil level should be checked when hot and also straight after shutting off the engine. Otherwise excess oil will run back down from the oil pump and mess with the reading. If you get the level right when hot, you can then make a mark for a cold level once it cools down.
Good info!
Pretty straight forward I'm getting ready to do this on my twin crusaders with borg warners.

Still appreciated
Thank you for sharing.
Rock on, Les!
Using the wrong oil or cheap oil can cause all kinds of problems. A Napa brand oil cause one transmission to foam out of the vent on top and run hot. I switched brands and the problem went away. The wrong oil with friction modifiers will cause the clutches to slip, burn and warp. The ONLY synthetic oil that I know of that works without slipping is Amsoil super shift. Very positive clutch engagement so keep the rpm under 800 to reduce shock load! A ten degree cooler housing was noted. If you have raised the power of the engine and you are pushing the limits of the v drive this oil may help keep the clutches from slipping and justify the oil cost.
Thanks for sharing. Is that a Malibu skier? I have an 86 in that same color scheme.
Yes! They are super fun little boats. This one is is not mine but It turns up in a few of my vids.
Great video! Simple, easy-to-understand directions. Did you change and refill with the boat in the water? Does boat-in-water also apply to oil changes? BTW, I used to live in Seattle. Are those the Cascades in the background? What waterway are you on?
Yes and yes. That's the (mighty) Fraser River.
Thanks man! Really helped!
very cool
how much oil you take out is a good indication of how much to put in.
Good point.
unless your boat flooded and you have water in the oil.
@@ethanepps5500 Yes, but you should be able to see water mixed in the oil if that's the case. If no water is detected, then it would be a good estimate. I read online that most of these transmissions take 2-quarts roughly of oil.
When checking the oil level, should we screw dipstick in all the way then unscrew and check or just leave it unscrewed and check it by mating to the case?
Most guys just dip it, I like to mate the dipstick to the case. If you think screwing it down makes a difference definitely check that level but it's not as exact as people think so close is close enough.
I want one!
Gary Mercer Me too !!
Gary i have a question on checking the fluid level in the Trans. My owners manuals says to run engine at 1500 rpm for two minutes then turn off motor and quickly check fluid level. This does not make since as the fluid has been displaced all around the inside so i do not trust what i see on the dip stick. In your video you filled and checked without starting motor ( so cold) is this how i should check my level?
I recommend following manufacturer's instructions.
Who's Gary?
Why the rattling noise? during idle
anyone know how much oil this takes says 4.9l online any help need to change mine
Well I messed up the sure of the lake was on fire and my transmission ran out of oil and went neutral all I had was engine oil and poured it in as quick as possible to get the boat moving instead of drifting towards the fire hopefully I haven’t done any permanent damage
I would drain the case asap, flush it a few times, new tranny fluid, run it, flush it again and hope I didn't spoil the seals. Good chance you did no damage but you did save your vessel and yourself. Well played.
How and why your tranny ran dry in the first place... may mean the seals were already gone.
