2.4 Mod VP? Dont know about that.But what I can tell You for sure, is in 1979 I bought my 2.4 It was called a 2.4 offshore.It came with chrome bore, vertical reeds,aluminium flywheel,cut heads,no rev limit.offshore midsection(above water exhaust)racing style cowl.It was claimed to be 240HP.I still have it.I had it ported,put a 225 front cover and bigger carbs on many years ago.For being a 30+ year old motor it still doesent give up a win very often.
