[James montgomery]

So I am taken my old Betke .21 and re doing it finish sanding it last night. Now I want to take the cable tubing out but not sure have to do it and take the wings off of it....I would like to put a ski in he middle like a jar has or should I use the wings to keep it the same....Will get all new hard ware for this and new cable tube as well....if any one has redone one of these sure could use the info

Jae not jar

James, I've used jumper cables and a car battery to get the tube out. Hook the cables up to the battery and then hook up the other side of the cables up to each end of the tube. It will heat up and should pull right out.

Thanks John have to try that.

Jim, This is one of our really, really old hulls. Are you looking to restore the boat to fun run with? If you are wanting to race competitively in the 21 class, save your self some time and buy a JAE kit from ZIPP. To respond to your questions.The shaft log can be removed by heating the brass tubing near the transom end to soften the epoxy holding the tubing to the bottom. The brass block soldered to the tubing will need to be removed before heating and pulling the tubing out. The motor mount was a plate style and should be removed and replaced with a rubber vibration side mount. The rear sponsons (wings) will work the way they are. They can be removed by just sawing them off and sanding the sides of the hull flat. I have tried putting the JAE style skid on our bottom design and it did not work very well!!! Did you get the front sponsons with the boat? If you want to build the boat to original, I have some OPS 21 engines that we used in these boats. I will sell them to you real cheap. They are in good shape and there are lots of spare parts. Jerry Betke

Hey Jerry thanks for the response back...I want to race this one ...I do have a jae that built last year...I have ran your boat in rough water and liked how well it handled the rough water....I will leave the wings on them if a center ski does not work very well on it....I do have the sponses for it...I bought it a few year back I believe from Mike Bette I believe with a 3.5 k@b in it....ran well....I would love to being this back to original but planed on maybe putting a nova dd in it but I would also be interested in the ops motors to...thank u for the info Jerry. ...james
