Cheap petrol filters for outboard engines.

[nigel1]

Beware of cheap petrol filters.

Late last year I bought 5 through Amazon, and fitted one in line on my Mariner 3.3 two stroke.

For the past three days anchored off Cushendall I noticed a drip of petrol from the outboard after I shut it down, closing the fuel tap stopped the drips. I thought it was the carb, usual problem of the needle valve sticking, but it did not seem an urgent fix, leave it until I get alongside in Ballycastle.

This morning, final run for dog ashore, the outboard stopped just as we left the jetty, fuel tank completely empty, only filled a couple of days ago.

This afternoon at Ballycastle, stripped down and cleaned the carb, re-assembled, filled fuel tank, and still a leak, but not the carb, but from around the fuel filter. A closer look showed that the two parts of the filter were coming apart, and petrol was pretty much running out of the filter.

Replaced filter with a different type I had.
Binned the defective filter and its four companions.

why do you need a filter?

Its a fair warning but your outboard should have a filter integral with the fuel tap

The previous owner of my 8hp Yamaha had one of these fitted in line from the remote tank. Seems a good bit of kit and and they do replacement filters.
Whether it is strictly needed or not I don't know but seeing as I have one I'll continue using it.

Thanks Vic, I had not realised there was an integral filter with the tap.

Not on mine .... and its not been replaced from new ..

In fact my 2hp ... 3.0hp ... 3.3hp ... none have filters as you show ... thats Mariner, Mercury and Johnson ... just plain fuel taps.

When I get back home .. will go have a look again to make sure !!

My Mariner 6hp came with a visible inline filter.

I quite like it as it confirms that fuel is getting through to the pump.
