Just closed on my 97 Carver Voyager 370 last week (as mentioned on the meet and greet page). Already received my new deck cushions for front (look great). Already had bottom painted, zincs switched and a few other things sorted.

But… I literally took it out for 20 minutes (taking home from painter) and sure as heck, one of the engines overheated. Not to worry, limped her back to my slip and even though a little difficult on one motor, made it back ok.

Had a mechanic look at it for a second opinion (I'm a pretty descent wrench but new to boats) and as silly as it sounds…the damn radiator cap was a bit rusty and popped off. Made a bit of a mess too but sh** happens. The surveyor did mention I should change out the caps but I didn't know that meant immediately (my mistake).

Anyway, mechanic tells me it's 1000.00 to flush the antifreeze, switch out the small anodes/zincs on heat exchanger and swap out the thermostats. This all looks way too simple to pay anyone $1000 plus parts!

Question is… First, I read the entire manual and looked online. Any trick to flushing these Gas 454's out since I can't just drain them as I would a typical car/truck? Risers were just sorted a year ago so kinda surprised the fluid and such is so bad already but nevertheless, can anyone recommend a good place that won't back order the parts I need such as the anodes, thermostats, under motor diaper and any gaskets?

I'm having trouble finding a site that shows a microfiche as I do when working on my motorbikes but again, really new to this. Thanks in advance for the help!
