275 hp Merc '93 low hours

[Mariner]

It is Cosgrov.. believe it or notI started to do it again! Cosworth it is. Mechanic told us he had never seen one and that it is a high end Commercial motor. It is my son's that's why I put phone # in ad. he might know whether it's 3.4liter I do know it is 275 hp and 6 cylinder, that the hour meter reads 300+. Mechanic said it hadn't been run
