Do as Lou has said, the cone clutch in the drive can act up if the wrong spec oil is put in it. I assume you don't know what oil was put in it? Get the Volvo Penta gear oil in it and try again.

old boats have old boat problems , give it a good going over ,learn how shit works , spend a few bucks on it now before you start using it , this will save you lots of head fvcks later down the track..

Well guys here’s the update. Pulled plug this morning and left it to drain while I pulled throttle cable I’m guessing it’s been changed recently bc it looks brand new. It still had string attached to it on throttle end lol so I think I’m gonna hold off for now on ordering a new one. Oil in lower unit is surprisingly nice and clean also no chunks of metal or signs of water getting into it only the normal metal shavings and not much of that either. I only recovered a little less than 2 quarts so it was low bc from what I read it should hold around 2.3 quarts unfortunately can’t find the Volvo penta oil nowhere in town so had to order it online and I went ahead and ordered a complete prop assembly. Everything should be here sometime next week and I’ll get oil in her the prop back on and replace the bellows that’s the part I’m not looking forward to since it looks like I gotta remove the entire lower unit so if you guys have any tips on dos and don’ts I’m all ears. I’m trying to get my hand on a manual to study up on it while I wait on parts to come in but haven’t found one for the 5.0 yet Thanks again for all of y’all’s help it’s greatly appreciated

What oil does your drive take? It doesn't need to be Volvo branded
I see it takes a GL5 synthetic oil. 71 oz. (All Volvo Penta SX Models 71 oz.)
I use Mobile 1 75-90. Now someone will come along and say it isn't GL5 rated but if you look on the back of the bottle you will see it's GL5
14 years and no issues on my DPS-A's


Maybe this will help you out

Your 290 has a clutch.

Bellows is not too bad. Take off the plastic cover, remove cable from linkage, remove little brass cable adaptor, remove the 6 nuts holding the drive to the shield, remove drive.

​​​​​​Loosen the shift cable holding bracket and slide it back so the cable is free. Remove exhaust bellows, circlip in drive end, hose clamp boat end. You probably don't have to, but I undo the water nipple and push it through the helmet, if it looks old, replace it, they are prone to cracks with age. Undo the uni bellows hose clamp, push the bellows out from the helmet (toward the boat), then pull it out the bottom. Reverse procedure to install.

I had a Cobra...
the SX looks very similar , my understanding is Volvo bought out Cobra and the SX is based on it

When i did my bellows the first time I bought a cheap aftermarket knock off ..... struggled for many hours to get the drive back on the boat
gouging the bellows quite a bit

Switched to OEM bellows .... slipped on without a problem

Fixed it

A few are the same, don't expect a 93 or older Cobra drive to have any parts that are the same. The SX style drive by both Volvo and OMC during the joint venture of the two, were the same.

What happened was that Volvo wanted OMC's conventional transom design so they bought into OMC, the transom mount was slightly modified and the drive was converted to cone clutch shifting, that became the new Cobra and Volvo SX (Cobra) as it was called for a few years. This started in '94, by '98 they bought out the remaining share of OMC's sterndrive unit and also got the new factory they built in Lexington Ky to build the Cobra.
PS OEM is better for parts like impellers and D/S bellows.

Well guys I found out the problem it was a spun prop. The insert was cracked like hell when I knocked it out of prop. So now I wait for the parts to come in so I can put her back together and get it in the water to have a little fun finally. Thank god bc I do believe the wifey increased my life insurance so she could take me out🤣🤣🤣

Check the gimbal bearing before putting the drive back on
grease it and the U joint.



No wifey onboard... until you have run it a couple of times

I made that mistake ....
new to me boat had NO hose clamps on the power head, previous owner used electrical ties
after an hour or so everything nice and hot the ties expanded enough to flood everything under the cowling
dried everything and limped to the marina to find some proper clamps
Then... no throttle response... she steered while I sat at back pretending to be a throttle cable

In the car on the way home... every time I opened my mouth to say something.... she'd cut me off "Sell it"
