Kwixdraw Posted December 17, 2009 Report Posted December 17, 2009 Is there a good fix for the cowl cracking along the center ridge on top and around the prop and cooling openings? Quote
rotorman Posted December 26, 2009 Report Posted December 26, 2009 There is an STC for this. I think the company that had it was in FL. Maybe the Mod squad. It was a Coy Jacobs deal. Essentially, it adds stiffeners under the upper cowl. I have heard it doesn't work too well. About 5 years ago, I had my cowl reworked locally. They added stiffeners and reworked the gelcoat. It looked good for a few years but is again cracking in the same places. There is also another STC, held by Lasar, that somehow tightens the lower cowl. The lower cowl's only structural attachments are along the backside. That means there is a huge load on those fastener as the air loads go up in the front. The cowl wants rotate upward. This causes fiberglass cracking along the upper fastening area. Quote
fantom Posted December 28, 2009 Report Posted December 28, 2009 Solution is a good boat fiberglass repairman and a little reinforcement. Or so I'm told. ;-) Quote
