hot risers on volvo V6
we have a 4.3 Gi V6 petrol Volvo Penta that the exhaust risers are getting warm when running?
it has had new manifolds, risers, thermostat, and stat housing?
when running on muffs it was getting plenty of water out the exhaust through transom shield but the risers were getting warm (hand on for any more than 15 seconds it was uncomfortable)
I thought maybe not enough tap pressure so put it in the water and it runs up to temp fine and does not get hot (engine or gauge) but the risers are still warm/hot?
with the revs increased the port riser was cooling but not starboard?
when I remove the two feed pipes off the bottom of the manifold water gushes out of the manifold not the pipes as I would have thought when running?
any ideas please???
