Mecury InBoard/OutBoard Cranks But will not Start

I got a 4 Cyl Merc. Inboard in a 79 Galaxy. I had it running just fine about a month ago, i put in in the garage for a few months to do some work on the hull and stuff, and changed out the batery. Now it will not start, I have checked the plug and stuff, i have a white spark at the plugs, and have good fuel flow. I am not sure about compression but sure it is good since i blows my finger out when i turn it over.

I bought this boat a few months ago and am still working out all the kinks in it. Like stll trying to figure out why i can not put in nutral while engine is running, have to shut it down first. if anyone has any sugestions, let me know on that one.

Other than that the boat run like a wild Banchie when i took it out the first time.

Try a squirt of carb cleaner in the carb then try to start. Might need to do this a few times. If nothing happens it's probably not a fuel problem. Beware of the fire breathing dragon. Keep an extinguisher handy.

The shift interrupter switch has most likely been tampered with. This poor little guy has been blamed for countless shift problems.

Get a Mercruiser manuals specific for your engine and sterndrive. Avoid the aftermarket manuals; they might be a little confusing.

RESPONCE TO JIM:

I pulled the carb off this morning and found that the intake was flooded, i cleaned it all out and bone dry now. I tried to start but same thing. could i need to change out my points, and wires and plugs? even though i have white spark?? also , i dont think that it is fireing on the cylndars,, i dont smell exaust out of the prop at all.

the shift interupter is there but it is not connected. how do i connect it??

Flooded with what? Gas? Water? How's your fuel quality? Plugs might still be fouled or water in the distributor, etc. Jim

Should be a wire(wires) hanging loose near the switch. Get the engine running before you connect up the switch, since disconnecting it covered up another problem that you will need to troubleshoot. "SSG Benedict" <loren_benedict2000@yahoo.com> wrote in message

I replaced plugs, points and everything. Had good spark and everything, but still no starting. I called up a marina and they said that from what i told them it is definately the starter. SO .... i guess i have to spend a couple houndred on that now,, lol SSG

What did you tell the marina that you didn't tell us? Wonder how they came to that conclusion. Did you check timing and/or dwell after you replaced the points?
