"Hello,
Boat: 1985 Sea Ray SRV255, twin 170's.
After two years of hard "resurrection" work, we are into the fine tuning stage and many thanks to the members here for help. I’m starting to work on better idle performance and starting, while it is now “good”, dependability in tight situations needs improvement. i.e. low idle, hot, tight busy docking maneuvering where it doesn’t die.
I know the carbs have not been touched since 1993 and probably not ever. First question is proper identification, the only numbers on the carbs (2-barrel) is a tag that is stamped MCM 170/470, 1389-8489; stamped on the side of the float bowl: 13898498 & 4703. There is NO manufacture’s casting mark.
Any source for a manual on these? And what should one expect to pay for a rebuild done by a reputable shop? This is not something I want to do myself if needed. I’ll discuss symptoms in a future post. (rebuild might not be needed)
Thanks in advance."
