- 7.4L MPI/Bravo3
winterizing my boat this year. I've got a 99 270da with a raw water cooler 454 MPI with a bravo 3, which means my water comes in through the outdrive, through the engine mounted raw water pump, through an oil cooler, power steering cooler, and cool fuel, then into the thermostat. I see a lot of people draining their motors through the blue plugs, then removing the hoses from the raw water pump to drain that area, reinstalling, and then pouring pink through the hoses attached to the thermostat so everything circulates through the motor, through the exhaust, and backwards through the raw water pickup and through the coolers.
My only concern is, what about the water line from the input of the raw water pump back through the outdrive? Wouldnt the impeller be in the way and cause the pink to not really get past the pump and make its way backwards out the drive? or am i overthinking it
