Flappers are at the top of the Y pipe hidden by the rubber exhaust hoses. They will melt & fall down inside the Y pipe if you have an overheat. These are a hold over from the original OMC Cobra design. Volvo said that they felt they weren’t effective & could block the exhaust if melted. They...
Ok that hole looks ok in that pic. Rusty water is probably from internal rust on the old cast iron engine & exhaust system.
BTW there is much debate on this forum about the value of filling the engine & exhaust manifolds with no tox antifreeze after draining for winterization. Some just drain...
Yes its a cone clutch and that Volvo SX is the equivalent of the Merc Bravo in strength they were used behind Chevrolet 454s so no worries on that end. While you could convert it to a Mercruiser it would be very expensive although you wouldn't have to do any transom work. Since you have a Ford...
The first couple of years they called it the Volvo SX Cobra, then they dropped the Cobra and it was just the SX.
The whole deal was like this....OMC ran into financial problems in the '90s with the Cobra shift cable recall and the Evinrude Ficht problems. Volvo wanted OMC's transom design...
thought so
well that's just Edelbrock's way of making you an expert on these things lol.
like I learned with the Quadrajet
I have a Sierra pump (old style mechanical) on mine that is working fine
Other than the fact that the fuel pressure is too high for a carbed engine, it is possible that on the Edelbrock carb one of the floats can hang up against the inside of the float bowl. I recall a post on this forum about this very problem.
The Edelbrock has 2 floats one on each side. Is this...
That’s definitely the joint venture drive made by Volvo; parts are the same as the Volvo. Get a new prop that’s going to cause vibrations. The drive not staying up is likely a valve inside the trim pump. That’s a problem I haven’t had yet though so can’t help on repairs. One thing I can suggest...
If you have one of those old original fuse boxes with the glass fuses check the tabs for oxidation; I had this problem one year & none of the gauges came on & engine didn’t crank. Fuse was not blown it was simply oxidation.
Did the old gauges work right?
If a trailer has 2 3500 lb axles and only one had brakes that’s only rated at being able to stop 3500 lbs. yet the trailer in total could weigh as much as 7,000 lbs. A pair of 10” brakes on a trailer that size & potential weight is frightening.
That 11 ft lbs always seemed too loose to me yet I know that’s what GM specified. The pre Vortec was 30-35 ft lbs. Just seemed odd for it to be 1/3 what the pre Vortec was. Was there that much a difference deference in the gaskets?
I never had one problem with the gaskets on the pre Vortec
I would air pressure test the cooling system see if it holds pressure over time & check the flatness of the sealing surfaces of the manifolds & elbows.
What tells me that it’s definitely a joint venture product is the sticker on the engines that says manufactured by Volvo Penta Marine of Lextington Kentucky. Yours is labeled an OMC Cobra with an OMC model # and OMC parts numbers. But, the VP & OMC parts were identical and at one time the part...
The 94-98 Cobras built during the joint venture years are exactly the same as the Volvo SX of the same year the only differences are color (SX silver, Cobra Charcoal Grey) and one has an OMC model # the other has a Volvo model #.
