So I’ve had my boat for six years and it’s always started and ran great but something has always bothered me and I’m hoping to put it to rest. When idling out of a shallow launch or flat with the motor trimmed up to keep the prop clear it for lack of a better word “loads up”... the idle gets rougher, exhaust gets pretty smoky, and unless I lower it back down it gets progressively worse. Once I get into deeper water and can lower the motor I raise the rpms a bit and we’re right back to normal.
Any ideas?? It seems like when a carburetor motor idles for a while and starts to flood. As far as how high it is trimmed, it’s starts to happen when the cowling gets much above level... never an issue otherwise I can troll SIing for an hour and not miss a beat. No fouled plugs. No good Yamaha mechanics around, everyone wants to just tear it apart.
