Well Folks, I have a coolant leak on my 470. After inspection I have narrowed it down to the front cam seal busting since coolant is leaking pretty good out of the drain passage inbetween the two cam seals as talked about in this post (http://www.sterndrives.com/470information/470coolantleakrepair.html)

There is no boating place within 150 miles of here that works on inboard motors, and the majority of auto shops here are the same (They are just hell to get to according to pretty much everyone Ive talked too...) Anyways, I was wondering if anyone had any advice because me and my buddy (an avid mechanic) are going to attempt to repair it ourselves. So any useful advice would be very much appreciated and taken into consideration. Thank you all for any input.

Re: Coolant Leak

Since you give no year of this "470" I would suggest you go to the Adults Only sticky at the top of this forum and download the oem service manual. 84 and earlier, you need manual #3. 85 and newer, #8.

You say you live in the south???? Google Mercruiser dealer and they will tell you where the closest one is.I had the local dealer in the north(actually kinda south/north)(or kinda west south north) replace the cam bushing.Thay were happy to sell me the new kit if I wanted to do it myself. Good luck,J (way south now!!!)

Re: Coolant Leak

Hey thanks I will google them, I have 2 mercruiser dealers in the town I reside in, but they refuse to work on inboards.... :( o well... and to Don S. I believe it is an 82 Mercruiser 470, although if they go by the last two numbers of the serial number then it is an 84... I will go out tomorrow and uncover it and get the serial number for you if that will help... Anyways I will download the manual you have listed and see what I can dig up, thank you both very much.
