Viper Mark 3 trailer younger height and ball size

[Dave Evans]

Hello,

I will finally be picking up Viper #104 in Long Beach. I have a new car which I need to set up for this trailer. Does anyone know the trailer tongue HEIGHT and BALL SIZE for a Mark 3 trailer?  This is the one with a dolly arrangement and I seem to recall it has fairly small tires. I jus bought a car with a twelve inch high ( to bottom) trailer socket. Help much appreciated on this kind of boring question;-).

Best regards,

David

it's 50mm..    I pulled it a LONG WAY on a 1 7/8".   The 1 7/8 will rattle a bit, throw a greasy piece of t shirt in there to take up the slack.

Are you going to sail Turkey Day @ ABYC??   you should..  :)

Thanks Tim! I think I read the height is 15" so a atraight ball shaft inverted should be close to level. I used to drive a truck where this question was more of an issue.

I'd love to sail T'day if life would quit getting in the way. I will definitely be on the line at Az's B'day regatta.

Proper size ball is strongly recommended:

Can also be found on eBay, I believe.

Dan,

I appreciate the lead on finding a 50mm trailer ball. My problem then is the 2" X 2" stock shanks come with a 1" hole. I do need to have a much longer shank made up for launching so I could have the welder close the hole and make up one for long haul and another for launching.

Thanks,

Dave

Huh??

[Dave Evans]

The 50mm balls have a 3/4" diameter bolt  and the 2"X2" receiver shanks come with a 1" hole, so a shim will be needed or the hole has to the welded closed.

I did find a Curt 14"( 2" X 2") extension so I don't have to back my car as far down the ramp

FYI, there are shank size adapters available from eTrailer.

Also... Be prepared to buy a bow roller if you launch it from a ramp that is at all steep. When launching and hauling the bow can hit the cross bar and set bolts for the mast support.  I bought an 8" one and u-bolts from Amazon and mounted it on the forward cross piece.  It will block the dolly nose from rolling back but I don't use it as a dolly since we don't have a usable lift.
