Possible Fuel Leak???

[Jefro573]

Hello All,

Well I am new to the boating world and this forum. I have loved it so far. I just picked up a 1998 Maxum 1800 XR with a 1997-98 120 hp Force 4 cyl. 2 stroke engine. It had been sitting for 2 years and hasn?t been started since. Well it started right up this weekend, however I noticed that fuel was leaking out of the bottom of the two silver parts in the front (See pic attached). I think these are the cylinders right? I dont know much about boat engines. I have been told that it is normal for a boat engine to leak fuel/oil. But it seems to be a lot of it. How much is normal if at all?

Thanks,
Jon

Where exactly is it coming out? If its coming out of the throut {round hole in front} you will have some come out when you stop not a lot. If coming out when running no good. if coming from bowl on bottom no good there is a gasket on bowl.

Its coming out of the little hole on the starboard side of the carburetor when the engine is running. not a steady stream but not drips either...it spits out off and on about every second if not faster...

if im seeing right fuel level coming up to high. should rebuild and relace float. here are the merc. part #s kit 809807a1 float f10346. I looked in sierra parts but I dont see the kit. also get a repair manual its more than worth it.

those are merc. #s couldnt find after market you will have to go to dealer to get. its a easy job to do when you take apart lay every thing out in order and buy a manual you should have that. good luck

Oh ok. Thank you very much. Yeah I will be getting a manual...never hurts to have one. I just started ripping out the deck last weekend, so once I get that going and pretty much done, I then jump on the engine. Thanks again for your help.
