I/o having trouble sucking up water
Had the hose on the muffs, had trouble sucking up water. I had to press hard on each side to keep the flow going. I could feel it surging when it was pulling water. When I put the antifreeze on with muffs, it just wouldn’t pull water at all. My water pump hasn’t been changed in 5 years and the boat hasn’t had much use. Is it the impeller?

3 years is usually considered max for raw water impeller life. On boats that don't get used much, the vanes tend to fold over and won't pump as well. Vanes can also break off sending rubber debris into the oil cooler and partially plugging it up. I'd definitely be replacing the impeller at 5 years. A back-flush on the oil cooler with a garden hose is a good thing to do if it hasn't been done since you owned it or if the impeller removed is missing material.
Having the anti-freeze container above or at eng level helps with getting good flow. |

How hard was it to get the muffs on the drive? I ALWAYS squeeze them together as hard as i can before putting any muffs on any drive. When you switched to antifreeze, were you just feeding it from the tank? Was the tank vented properly and no loops in the hose to cause an air lock?

I had to use a bilge pump to pump the antifreeze thru the muffs on my bravo drive.
After I installed a sea strainer, it was easy just putting the antifreeze there. |

It would probably take less than an hour to install a freshwater flush kit on your boat and then simply pump the antifreeze in through the flush kit.
