I have a cruiser that stays in the water all year, has twin 95 volvo 7.4's in it. I followed the winterization protocols per the manual and I know I've unhooked and drained everything.
My paranoia is setting in on the fact that there is no way to get the motors 100% perfectly level. They slightly lean towards the back. Should I have briefly fired them up with the water inlet unhooked to blow out anything left in the exhaust manifolds? Or will they still drain ok with the block plugs out and the water hoses unhooked. There is no hose or plug on the back of the manifold to drain on these motors.
