Help!!

[ready2sinkit]

we have a 1994 maxum boat starting issues with a 3L mercruiser, replaced new battery, new starter, new alternator and tune-up. This is what happens, it runs sometimes and dies after we shut if off. GRRR... going on now for two years about ready to sink it. Just past Saturday got ready to put it into the water try to turn the key .. nothing no clicking nothing husband about ready to burn it. The mechanic doesn't know what the heck it is .... has any one ever had these problems before? any help???

Is there a black box computer controlling the engine, sometimes called a CDI?

If you have a coil, need to replace CDI and coil at same time, a bad one of either can mess up both.

Sounds electrical anyhow, without further information can't help more.

When replacing these parts, be wary of bootlegs/counterfits. Get original manuf. parts when possible, direct from a dealer. Cheep electrical parts will just keep you from fixing the problem.

You should read the following thread - maybe repost your question in that forum or thread.
