    Old ford 302 no spark

    I would use a piston stop tool to verify you are indeed on TDC however it looks like you may need a new harmonic damper (or your piston is not at TDC) normally to replace that, there is not enough room in front to get a damper puller tool in there. the motor may need to come out.

    Flagstone Patio pitched slightly towards house and water collects

    Nearly all of the 90s jet boat hulls are balsa cored. This gave them strength and light weight vs a solid hull Some boats today still use balsa core on decks The area you have circled on your pic looks like part of the core is exposed

    Evinrude 115Hp V4 Project Rebuild / Repowering a Fourwinns Fling Turbo jet boat
