Twin 454 question
alright guys I live in the Midwest where it gets freezing temps in the winter. I have to winterize boat ever year. What I’ve done in the past is pulled drain plug on block and pulled all hoses and that’s worked for me. But that was on a single motor boat. I now have a 89 formula 272 sr1 with twin 454s. Both motors are out right now. Can’t do what I did with drain plugs and hoses because it’s so damn tight. Is there anything I can do to drain holes before I drop motors to make a attachment or something to drain blocks???

On every motor I have put in a boat the last decade go to Home Depot and get a 1/2 long all thread, a coupler and a plug for both sides all in brass. More then once I have had the block threads turn to crap after a couple years. So you install the all thread in the block, attach the coupler to it and then the plug is always brass on brass The best 5 dollar mod I have ever made to a motor. They also stick out from the block so they are easier to find in the dark. I have the wing style block drains on one motor. They seem to clog up easier and harder to clear. JMHO.
