Hi Everyone,<br />I recently found this site and realize there is a ton of information here. I am hoping you can save me some mistake time 
I have a 1989 Larson Senza with 5.7 mercruiser I/O. The boat is in good shape but the back corner of the floor was spongy. so I took out all the seating and started pulling up the carpet. As suspected the wood was rotted. So I cut away some of the plywood and drained the gas tank and pulled that out. I took some pics I will try post them soon. <br /><br />Ok now the questions . The port side stringer seems to be in pretty good shape , except for a couple of places. I am considering using "Git Rot" or something similar. Does anyone have any experiece with this stuff anything to watch out for? <br />I also noticed the wood on either side of the tank is rotted. It is only 3/4 inch plywood. I assume it is there to have a place to fasten the aluminum tank (not structural?) How ever the bottom few inches are glassed into the hull. I thought about placing some 1/4 inch along there and using "Sea cast pourable transom mixture". Again anyone use this product? Good ,bad and the ugly? <br />The original deck was not glassed over (just marine carpet). The plywood was glassed to the exterior bulkheads (about 6 inches in). After replacing the plywood I plan on resin coating the new plywood or even a layer of fiberglass then the carpet.<br />Well I am sorry for the long post but just trying to give the details. Thanks for any info. I hope to be able to return the favor in the future.<br />New to boat rebuilding but not new to boating
