I just bought a 1988 Reinell 191ST inboard with a blown up 4.3 litre v-6. I replaced the engine and tried to start it up. It fired right up but as soon as I released the key from the start position to the on position the boat would die. I found a 30 amp fuse on the kill switch was blown and replaced it with a 10 amp fuse (I didn't know if the 30 amp fuse was too big) and it blew the 10 amp fuse.I don't have a schematic and it's an in-line fuse. Should I put the 30 amp fuse in and try again or can you tell me where I might have another problem. The guy I bought the boat from was on the lake last August with his 2 small grand daughters. I think when the engine froze up he really panicked and tried to turn the engine over until he blew the 30 amp fuse. Any Ideas?......Thanks for looking
