1979 CVX-20 HIN
« on: July 19, 2021, 05:17:25 PM »
Can only find 7714695 on the starboard side of transom. Not sure what the number is?  Our Game & Fish needs a 12 digit HIN.  Can’t find any other number.
Any ideas?

That's an odd HIN ?
Should be a "GCV" in front of the numbers and would give you the 12 digits.
(see picture below of a 1976 CV16's HIN)

Check list of numbers here ...
Scroll down to HIN's list.

How do you know it's a 1979 model ?
From the reg. or title ?
Where are you located ?

I am in Little Rock, AR. Where is your # located? Previous owner said it was a 79, I have found nothing to say one way or another. The engine and pump have #’s, but not sure if they mean anything.

I'll check your pump serial numbers out ..


All HIN are located on right hand side of stern.
From Dane ...

The HIN (Hull identification number) was a federal requirement beginning in Nov 1972, for 1973 model boats. It starts with a 3 letter Manufacturer identification code, followed by a 5 digit serial number and ending with the date of manufacture. The reason for this requirement was for safety and defect recalls. The law allowed for two methods of display. The one Glastron chose was to list the model year M and then a letter for the month of manufacture. August was the traditional first month of building new model year boats so A= August, B=Sept, etc.
The "M" means that Glastron was using the optional display of model year instead of certificate date. "M" stands for model year.
When this law went into effect manufacturers didn't like that they would have to stamp 72 into a 1973 model hull so the law allowed the optional method that Glastron used of stamping the model year and then a month code.

Some (never found one on my boat) have a tag with HIN glassed in around dash area.
Some were small pieces of paper and others were "IBM" cards.
Most were found around steering wheel.

Jakekl,

Welcome to the site.
Your 7714695 number appears to be the serial number of the 12JE pump. I don't know why is was engraved in the fiberglass. I would expect the 12 digit HIN to be further to the right just under the rub rail. If the boat has been previously restored the number might have been filled in.

The secondary hull number wasn't a requirement until 1984. I don't know if Glastron was adding the secondary number in 1979 or not. If they were, check the locations that Gregg mentioned. Either behind the dash or maybe under the deck behind the dash.

Did your boat come with a registration card or title? If so, the HIN is probably listed on that card. If the boat has state registration numbers on it you might be able to ask your Fish and Game dept to search their records for a Hull number.

Hey thanks. Glad to be here. A wealth of information. I might pull the rub rail.  The old registration lists the pump number engraved on the boat. No other number has been found. I looked under the dash, but will look again.

The apricot orange picture above is from my CV16.  I found it one day under the dash. In order to see it I was sooo far under there I wasn’t sure I was going to get out.  😀. In other words, waaay under.  Bring a flashlight and a cell phone in case you need to call for help.  😂

Is there any signs of repaired damage on right side of stern ?
Maybe boat was repaired and they just used the only number they could find from the pump ?
Just guessing ...

I am guessing the aft was damaged at some point. Both screws and rivets holding the rub rail on. No numbers under the rail. Did find a card under the dash. Could not make out any useful information. Tried to remove it but tore it. I guess I will need our G&F to issue me a new number to be able to register the boat.

I don't know how hard it is to get a new HIN in your state, you'll have to call and ask.
Any luck finding the year your motor was built ?
I couldn't find any info from your pump serial number other then model.

I circled where the serial number should be on this image. If you blow up a full resolution image and play with contrast you might be able to make out the number.

The suffix for the HIN would be at the far right side of this card and would likely be M79 with a letter for the month of manufacture after the 79

Using this image that Gregg posted earlier where the number is easy to read, the 12 digit HIN would be GCV16200M80E

GCV= manufacturers identification for Glastron Carlson
16200 = serial number
M80E = Date code for 1980 model manufactured in December of 1979. E=5th month A= August B=Sept etc
