Drain screws/bolts on carburator 115hp /1992

[Joche]

Has anybody any good ideas on how to fix the drain screws in the bottom of the carburators so they wont fall into the sea if/when I have to drain the carburators. Mickey Mouse screws? drill a hole and fasten a wire? <br /><br />This problem occurs sometimes in the winter water is about +4 C and air is about -5 to -10 C.<br /><br />Thanks<br />Joche

Those aren't really drain screws. They're access screws to the main orfices. They can be used to drain the carbs but that isn't their main function. <br />Why do ya need to drain the carbs anyway?<br /><br />c/6<br />Hooty

Thank you for the clarification. I have comed to notice that in the autumn/winter/early spring there tend to be some ice buildup in the carbs, when you have been running for a while and then take a 10-20min break. Even if I but metanol in the gas to fix the waterproblem. The first time it happend I was driving slow among ice and the engine just died. After a while of this and that an the other I bled the carbs. and it started up. It could have been that the engine just melted the ice and the metanol did it thing. The reason why I don't want to go WOT in the thin ice or ice areas is that it will eventually kill my boat (Buster Magnum) which only has about 4 mm of marinal aluminium in its hull. There is a picture from early november, and after November the ice just gets thicker and I have to stick to routes until it is snowmobil time until April.<br /> http://www.fmnh.helsinki.fi/users/schantz/november.jpg <br /><br />Joche

Joche, Are you sure the condensation is forming in the carb or could you have condensation/water in your fuel tank? Do you use a water/fuel separating filter?

I have a "working" waterseparator which means that it works as good as it can under these circumstances. The eqation with minus (centigrade) in the air and almost minus in the water is a tricky one. To illustrate the situation: I have a snowshowel in the boat to get the snow/water mixture out before it cloggs upp the drainage in the boat.<br /> http://www.fmnh.helsinki.fi/users/schantz/img_0471.jpg http://www.fmnh.helsinki.fi/users/schantz/img_0472.jpg <br />These pictures were taken last spring.<br /><br />I hope I'm wrong but it seems to me that after a while (2-3 days) of boating eventually there will be a problem with the carbs and it helps after I drain them unless I can find a place were I can use WOT for a while. <br /><br />I wonder how the professional north/south pole guys does it?<br /><br />Any help is greeted wtih open arms.<br /><br />Joche
