I recently bought small boat with suzuki 9.9 oil injected. starts and runs great at first with strong water stream from discharge hole but water stops pissing after few minutes and engine overheats. I suspect a bad impeller but strangely, when hose is hooked up to motor with hose attachment the water discharge stays strong and does not overheat. When run in a barrel, water stream stops pissing?? Maybe because hose water is under pressure? I am going to look at impeller but wonder if anything else could obstruct the water flow??
Anyone had this problem? Thanks for any suggestions.
