I recently put a new motor in my boat due to the old one having a warped block and head between two cylinders. The new motor cranks over but won't start. I don't believe it has any spark. I've replaced the coil, 90 amp starter fuse, 50 amp circuit breaker and the electronics in the distributor. Still same issue. All of my gauges and lights and everything work. I know very little about engines and any help would be appreciated. Thanks.
