I have a Lehr propane 4hp outboard motor that is a functional clone of the Yamaha F4MSHB. I've taken out the propane components and installed a fuel pump, carburetor and intake to convert it to run on gasoline. Only thing I'm having trouble with is I'm not sure how to route some (water/cooling?) hoses. Please see attached pictures:

Does anyone have a 2000-2003 circa Yamaha F4 4hp outboard who could tell me how their hoses are routed?

Found what I needed from the service manual. The hose from thermostat goes to the fitting in my second picture, it is a cooling hose. The other hoses in pic 4 were breather hoses. One goes to the intake silencer, other goes to a fitting near the flywheel.
