I bought an 87 capri bowrider 125 force outboard,<br />The boat had not been run in 5 years. I cannot find a drain on the gas tank and it looks like the boat was built around the tank so I cannot pull it. I havb two problems. this wood looking stuff keeps cogging the lines even after 5 or 6 tanks I do not know what it is or how to get rid of it. The other is I have a small leak in the tank somewhere. any suggestions.
