Customer Question
My Mariner 3.5 hp...

My Mariner 3.5 hp outboard is reving too high at idle.

Mechanic's Assistant: Sometimes boat issues seem like they'll be really complicated, but end up being easy to fix. The Marine Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so the Marine Mechanic can help you best.

There was dirt in the fuel which blocked the idle jet on the carburettor. I took this apart and cleaned it out. Put fresh fuel in the tank. Cleaned the fuel lines. The inline fuel filter is damaged and I can’t get a replacement here in Egypt so I have put a small inline filter similar to mower/ motorbike engines. When I start up the engine revs really high.

Mechanic's Assistant: Is there anything else the Marine Mechanic should be aware of?

Fuel is gravity fed, there is no fuel pump.
