Mariner 150 running issues
I’ve a late ‘80s Mariner 150hp 2 stroke which is having fuelling issues.
It runs great for about 20 / 30 secs, but then bogs down and will cut out unless the fuel line bulb is squeezed. It will then run fine again for another 20 / 30 secs. It does this both when idling and under load.
So far I’ve changed the fuel pump and also replaced the fuel line connectors both at the tank and engine (in case it was sucking in some air).
Any ideas what to try next?
