Hello,

she's old but shes pretty and actually getting interior redone at the moment time to bring the past to life.

My question is I never had a boat with a 7.4L Merc & Bravo 1 Outdrive that being said never had a seawater pump always just the water impeller in the outdrive.

SO...... How can I run the antifreeze thru this boat does the outdrives veins still pull water or is it the thru water inlet on the portside hull only thing is I cant see this a fitting or strainer I actually have no idea what that water inlet is for.

Basically I dont wanna burn my boat up and I have no idea if i can just use the tool i have been using for years to winterize my boat.

and any advice for the toilet and sink etc consider I just bought the boat and know nothing about winterizing it


ANY ADVISE will be much much obliged.
