Nice to see another 15 Whaler restored. I'm happy to see you opted for the Yamaha over the Suzuki. While the Suzuki is a great motor, it's almost 100-lbs heavier than the Yamama.

Test the fuel tank in place at the recommended 3-PSI or less. If you decide to remove the tank, there's the chance the foam adhered to the tank and will act like glue, holding it in place.
