Risers are too short for the engine/hull configuration. You'll never get the
dealer to admit it, but check around with other owners of your hull/engine combo in your area and see who else has the same tbl. Best of luck Mike |

Mike, I was on the fence about that one. Typically you experience hydrolock
symptoms at least some times with water coming back through the exhaust. If the boat was used as an overnighter that might increase the possibility. A lot of factors have to happen just right to get water through the exhaust and past the rings without the operator noticing it when they try to start the engine. Do you know if volvo makes riser extenders similar to the merc ones? Their manifolds look a lot like mercs. If that's the problem then the fix is fairly straight forward. Also makes the problem entirely Larson's, Volvo has not control over engine placement relative to the waterline beyond recomendations which I'm sure they make. Ralph, here's what the riser extenders look like for merc. You can see they are simply blocks with the correct passsages designed to go between the manifolds and the risers. They raise the exhaust riser for situations where the boat engine sits low in the hull. It keeps the riser far enough above the waterline to keep water from entering the exhaust while the engine is off. If I were at a dealer I'd be tempted to just put one agains a volvo riser to see if the pattern is the same. I know next to nothing about volvo so I don't know if they have their own riser extenders. Volvo has the advantage of being better engineered, merc has been around forever. Due to overwhelming numbers they have had to confront a lot of real world problems. http://www.perfprotech.com/Home/Tech...0manifolds.htm "CaptMP" wrote in message ...
