On my last outing on the boat cruising along at 25 knots, the engine just shut off. She started a couple of times, but died when I pushed the throttle, and then not to start again. Compression readings showed low compression on the starboard side of the engine 62, 58 & 58, port side were all in the 90s. I pulled the head and it was clear the rubber seal around the pistons were all breached, I cleaned everything up, new seals, sealant around the water jackets and torqued it back on. New readings are 90, 78 & 92 (the 78 indicates a worn ring, but I'm thinking it should still start), but the engine would not start. I get spark at all cylinders, the engine actually sputtered during one of these spark tests, strange? I can smell fuel on the plugs when I pull them out. I went through a bulk of the electrical system tests, I tried to run through the fuel system tests, but some of the tests suggest the engine be running, which mine doesn't. I rebuilt the lift pump, the electric fuel pump is pumping fuel just fine.

I'm hoping someone here would have some suggestions for me...
