Actually somewhat similar:
My upper crack is near where yours is, indicating a high probability of yours being an early model '06. If so, you should still get and apply the free kit. It contains a fiberglass reinforcement for the nose of the drivewell with epoxy, sandpaper and instructions (see picture in earlier post). It also has two longer cam screws that will stabilize the area where your break is by extending the screw support beyond it. Note, this kit is specifically for the Adventure, not the Revo!
{To help identify your version, the later '06 models don't have the lip at the nose of the drivewell that you see in the earlier post. They have a second button hole on the bottom of the hull (as I recall) right in front of the drivewell and the longer cam screws already installed.)For the reinforcement I used two applications. The first is 3M ScotchWeld DP 8010 and the second is almost the same but with a filler added -- DP 8010NS. 3M can tell you who sells it in your area. Each package runs about $20. It has a 6 month shelf life -- check the date on your product.
Tips on using it:
This is a 10:1 mixing ratio. You don't need the expensive special dispenser or mixer they might try to sell you. Get two different diameter dowels to use as plungers. Pre-mark the dowels to dispense about 1/2 batch at a time. Mix well with a stick.
Prep: medium sand the columns and the base around the columns. Clean everything with alcohol and let it dry.
You'll have about 5 minutes working time (they say 10 -- don't believe it). Have everything figured out and prepped before mixing. Concentrate on one column at a time, one column per batch, applied with double latex gloved fingers from the center hatch. Apply by feel but keep a mirror to inspect your work. Be in a ventilated or open area. Do a practice run before mixing.
Repeat the process on the other side with your next batch.
I did a second application with the NS version to add structure after the first application has cured.
I tried some pre-cut mesh for additional structure but made a mess of it and abandoned the idea. Didn't end up needing it anyway.
Finished product -- customized cam columns:
If anyone steals your boat you can identify it immediately!
I hoped for a year's service out of this. So far it's been over 2, well over 1000 miles and it shows no sign of failing. This boat does boat wake sprints that probably tore the cam columns apart in the first place. Amazing stuff! Let me know if you have any questions.
