Thanks for the input! It really looks identical to that '68 V-142, however the part of the splash well right behind the seat on mine goes straight across, instead of dipping down in front of the motor.
I checked under the splash well for a serial number with no luck, the dash has been reinforced so if there was something there before it is now covered.
It was yellow under the maroon burgundy. But looking at some of the Glastron spec sheets I don't see a yellow..
It is an '87 Suzuki 55 hp on it, pulls skiers, does 37 mph on the GPS and is up on plane in a matter of seconds. Great little boat.
I also attached a pic of the bottom of the hull, not sure if it would help?
