We could do a little investigation on our own here. Doarn's CVZ-18 and my CVZ18 are the same production year. Could we compare the two HIN numbers and see if their would be any relivance? Maybe it would also help to have a HIN for a couple 1978 CVX-18 to compare to also since the haul designs are relatively the same.
Here is the HIN for my '78 CVX 18 GCV10480M78H Color is Silver and OMC outdrive
'80 CVX 18 GCV16389M80F Color is Champagne w/ beige and Mercruiser outdrive
Let's assume there is a method to the Hin # madness and that basic info is contained in the Hin, organized similar to Vin #'s on your auto.
We know that "GCV" indicates Glastron Carlson built in Anaheim,Ca.
Let's assume the next series of numbers represents the consecutive unit or build number, for the '78 that is 10480, for the '80 it's 16381.
The next segment is 'M'. This could designate the hull design as both boats are CVX 18's and both have the 'M' in common. I suspect
hull design because other CVX's, built in Anaheim , listed in this thread have the 'M'.
That leaves a combination of 2 numbers and a letter. These could indicate outdrive and engine combination.
This method would give the factory or dealer basic info that could identify the boat for any warranty issues.
What do you guys think. Am I on the right track or just blowing smoke.
