The oil fill plug is behind the cover on the rear top of the drive. The cover is held on by 2 screws. The plug is a allen head -- 5/16" if I remember right. Make sure you leave the dip stick out while filling.<br /> The drive is drained and filled while up because thats the way Volvo designed it.<br /> You can change the lube the same as a Merc if you want to. The only problem with doing like a Merc is if you fill too fast the oil will come out the dip stick hole before it shows up on the dip stick because the dip stick goes down inside a shaft and the only way for oil to get in this shaft is thru a very small hole.<br /> Hope this helps --- MUC

Re: Volvo Penta 270 outdrive. Oil in from top or bottom?

[fflaguna]

I'm hoping someone with a Volvo Penta 270 outdrive will reply. I found my manual and what it says follows. <br /><br />Draining<br /><br />Remove the oil dipstick. TILT THE DRIVE. Remove the plug underneath on the propeller housing and let the oil drain out. Refit the plug with it's O ring.<br /><br />Filling<br /><br />Remove the oil filler plug. Fill with oil. Refit the plug together with it's O ring. LOWER THE DRIVE.Check the oil with the dipstick which must not be screwed down when checking the level. Fill to the correct level through the dipstick hole.<br /><br />So here is where I am confused. No problem with draining WHILE TILTED UP as the manual says but where is the oil filler plug. The only openings I see are the drain and dipstick holes. I also don't understand why, per the manual, the drive is tilted up while draining and filling. Obviously oil in the Volvo Penta outdrives are not changed like the Merc or OMC. I sure need some help to do what should be a simple procedure.

Re: DP290 milky oil. How tricky is a seal change?

[ryepdx]

If the bellows leak, and water gets in, the front seal in the drive is not designed to keep water out, only oil in. So when the drive is warm and cooling down after use, it will suck water into the drive.
On a boat that's in the water year round, I would STRONGLY suggest you change that bellows yearly. It's a very easy job, and you don't have to remove the drive, only the upper gear box. Should take only an hour or less to change the bellows and the gear lube.
if there is water in the bellows, and it got past the seal in the flywheel cover, you could very well have the primary shaft bearing/s going bad too. You will have to look at that when the upper gear box is off. It very well could mean an engine pull to repair. [links]

Over here they want to charge nearly ?300 ($480) to have the boat removed and stored on legs for 2 weeks using a hydraulic sling system. All trailers are unavailable at the minute, so we're pretty short on other options. here

you can add coffee, Orange juice or plain water.
however warrenty will be void if the GL5 SYNTHETIC oil is NOT used.
does not have to be Volvo but it must be the 75W90 GL5 synthetic.
why, I dunno. same as some black painted TBI 5.7 motors specify warrenty is void if synthetic oil is used and that same 5.7 TBI with a red dress on says its void if synthetic is not used.
put in whats reccomended and odds are life will be gooooood. [links]

Re: Volvo I/O Lower Unit Gear Oil Change

[robmon]

Rodbolt I hear ya and will go with Penta recommended lube so I don't violate my warranty. Disappointed that Mercruiser/Quicksilver were elusive in their oil makeup and missing the SAE and other quality markings. Better the devil you know.

Here's a picture of a half quart of oil I drained out first.

My dad thought it would be the most obvious suspects, bad head gasket, cracked head, or cracked block. We hooked the boat up to water, pulled the spark plugs, and spun the motor over, but no water came out of any of the cylinders. here

I thought maybe water was in the gas so I went and bought a water separator to install. I haven't yet done so, but wound up noticing I had too much oil so I went to drain some out. When I did, I found that I had a decent amount of water in the oil. Where you put the oil in the boat looks like there is white grease in there.

My boat ran great all last year and the first couple trips this season, but last time out I had some issues with it lacking power. As I was driving down the river it really seemed to be dragging, but would intermittently get a shot of power and run like it always has. I was able to pull a wakeboarder fine, then dropped her off at the bank and my buddy got behind the boat to wakeboard. The boat wouldn't even plane out at that point with only 3 people in my boat. more

Here's a little background on some issues I had, but in short, my impeller went out and my boat ran hot a couple years ago, which required me to replace the thermostat, impeller, and the rubber hoses connecting to water manifold.
