manifold hose question

[rebars1]

Just aquired 1983 23' Chris Craft. The original engine was Chevy 350 with log manifolds. The current engine is a Chevy 350 from a Volvo Penta set up with a closed cooling system. It is installed to the mercruiser Alpha 1 drive using the original transom/shift attachments. They kept the Volvo center riser manifolds and attached the exhaust to the Y pipes. <br /><br />I'm new to closed cooling systems and Volvo Penta set ups. I've noticed that the manifolds have one water hose only, connected at the front ends. No other hoses attach to the maifold or riser. Is the a typical Volve setup with closed water cooling? The port side riser and manifold run hot (on muffs), the starboard side runs warm, not hot.<br /><br />I've attempted to attach some photos:<br /><br /> http://i23.photobucket.com/albums/b365/rebars1/1bb7cb1f.jpg <br /><br /> http://i23.photobucket.com/albums/b365/rebars1/engineside.jpg <br /><br /> http://i23.photobucket.com/albums/b365/rebars1/engineside2.jpg

Re: manifold hose question

The set-up looks right, I would look at the right riser for scale in the water dump.... Only a gasket spent...My set-up is a walk around compared to yours.....JK

I should say mine looks less complex...From what I see it looks right....JK

Re: manifold hose question

Thanks, J.kopec. I have to replace the port riser anyway because it has a crack near the hose, I assume from getting too hot.<br /><br /><br />Also, this engine has electronic ignition with a carburator. I have not seen that combination before...is it common?

Thanks JK. I'll pick up some manuals and have at it.
