1977 Suzuki 115 over heating

[SDVANDAL]

Have a 77' Suzuki 115 that is over heating when ran in the water but runs fine when a hose is attached.
When idling or or at high rpms. in neutral no problems. But as soon as you put it in gear and start to go on the water, the water outlet has little to no stream and then engine starts to over heat.
Also i can not find parts for this engine

It sounds like your impeller is bad or water pump is bad. Did you look for parts on this sponser's site?

The water pump and impeller look fine some of corrosion down there.
