I have a 5.7 mercruiser, should I get the dual Muffs, I currently have a Muffs for the 3.0 mercruiser, are they to small for the 5.7 liter. As ignorant as I am on the subject, I don't know that and how fast does the engine 'suck up' fluid out of the DIY Winterization flush kit. Intuitively I would think it would suck 5 gallons really fast but then I again, I know absolutely nothing. Should prop always be taken off when running engine out of water with muffs? Thank you.
