Again what style carberator??Q jet or webber,if you dont know letus know what year and make and model your engine is..water can be coming from anywhere,,if your engine is running to cold it couls be getting condonsation under the valve covers and sucking it in through the breathers..you may want to check your oil too,you could have a internal water leak in the engine and that could be sucked through the breathers in to the carb..

A webber carb has a electric choke and the power wire may have came off thats why its stuck closed but it should be idleing chitty...a q jet has a mechanical choke that works off of he reastat from the port that heats the intake..that could be bad or the choke lever couls have came off..

Just use wire or a zip tie to hold it open. Boats really don't need chokes anyway. Most people are not boating when its cold out.

My Merc Weber carb used reastat also.

I am thinking about buying a new carb. Any recomendations? The motor is a 1996 454 Mag.

What state yo live in?

You do not need a new carb. You just need to fix the choke. You won't see any noticeable performance gains with a new carb.

Does your carb use an electric choke or a spring reastat??? a new electric choke kit is available from merc for about $90.

I live in Indiana.

When I was out last weekend the choke seemed to be working correctly. It was open when I got to the beach, but after sitting all day it was still hard to start.

I am trying to figure out what kind it is. It has a W stamped on the top so I would assume that it is a Weber, but the only numbers I see on the carb is 8867. I cant seem to find any info if these are the right numbers. It does look like the carb in Griff's link.

Tie wrap the choke open and run it.

That is a Weber Carb in the link.

I would bet that the choke closed while you were on the beach. Just for the heck of it, use a zip tie or wire and hold it open for a day. It may be just a little harder to start cold, but see if it starts easily when its already been running and warmed up.

I zip tied the choke open. After stopping for a few minutes it was hard to start again. Any other ideas?
