1995 foreman 400 water in engine

Hello, Ive got an issue with a foreman 400 that I cant seem to track down. Somehow water is entering the engine from somewhere. Its definitely water and not condensation. The water and slush this quad runs through is only a couple inches or so deep.
Ive checked the breather tube for damage and routing and Ive replaced the seal on the motor behind the recoil.
There is a speedometer on this machine that looks like it was a optional accessory because its mounted on the rack. The speedo cable plugs into the rear of the engine just in front of the rear left tire. Im suspecting this is where the water is entering.
Ive already disconnected the cable and housing and re-installed using rtv gasket maker but water is still seeping in from somewhere. Im still thinking thats the entry point and have no problem with disconnecting it altogether and covering up the hole with the original cover.
If anyone has had the same issue please respond, Im open to suggestions. Thanks

Welcome to the forums you will get an answer real soon
^^^^^^^agreed and have you checked the air box to see if it is wet or damp?
Oh also it takes about 4 oil changes to get the water out. one change will not do it trust me I know. also if it is really bad you might have to tear the engine down to get it all out

even if it is wet..or damp..that wouldn't explain the water in the engine just from ridding through a couple inches of again..2 inches of water to one person....might be 4 feet to another !
This is true. Just thinking the worst I guess.
crankcase vent is on and not split or have holes in it?
If the owner has got it in some water over 2ft. it could get in around the snorkel at the air box if not sealed well.
