Power

Why do you loose power when your in a river full of leaves
What happens to your engine what gets blocked because it happens to me
It was like it was slipping until I went backwards witch seem to clear
The problem for a bit but this happened about five or six times
Is it the leaves on the river cheers

There's a mesh/grill on them which blocks up, I doubt it's possible to engineer a mesh which doesn't block.

If the leaves are long grassy weedy types then it could be tangled round your prop too.

I'd go for fouled propeller too.
If the engine is overheating it will tell you. When it goes into limp mode it will tell you!

Just looked at your profile. Smallish boat - what engine? It may not have all that electronic gubbins.

Was the water shallow? Could the prop have been in the mud?

>>>Why do you loose power when your in a river full of leaves

Is it an old tech 2-stroke or a more modern motor with electronics?

If the intake was blocking enough to stop cooling to a degree where the engine overheated enough to slow then you should have noticed the tell-tale stop... and sadly you would already have done some damage.

But I don't think it's this... it's so much more likely this is weed on the prop which is being cleared when you reverse... next time out when it gets sluggish check the tell tale is OK then stop the engine and raise it before you reverse... to look for weed.

We have some rivers very near us that don't need any registration fees but you have to stop every few minutes to clear the weed so I've never used them since I found this out on the first trip.
