This guy I know has a 90's 200 Merc. I told him I would do the work on his engine instead of the shop in order to save him some money. I have done all the work on my engines so I am not good with shop prices.<br /><br />He needs:<br />New head gasket<br />Carbs cleaned<br />New tstats<br />New Water Pump<br />and Full Winterization<br /><br />What would a shop charge for this? This way I can properly scale down the charge.
