Sierra-18-7789-Fuel-Water-Separator-Filter
by Jack from Eldora, New Jersey on August 20, 2017
wrong filters, returning freight cost me as much as the original purchase including the shipping to me. iboats doesn't offer prepaid returns so i will just discard the wrong filters and will reorder from a company which pays for return shipping.

Direct replacement for the BRP stock filter at a third the price. Bought multiple to replace the filter every year as recommended. Iboats sent the filters fast.

Fuel Filter

Catalog said it was a replacement for the Volvo Penta filter. GSI series engine specs call for a 10 micron. This filter is rated 21 micron. I'll update to correct size shortly.

Affordable and quick.
by Daniel from Hills, Iowa on July 06, 2012
I haven't had a chance to run it in the water yet but it works on the muffs. Not too much to say, it fits right and was shipped quick. Shipped out of Ankeny, IA and I live in Hills, IA so I had my parts the next morning.

Q:
With this fit 1992 omc king cobra 351?
A:
If your original is the 21 micron then yes this will work for your motor.


Q:
I am replacing a OMC filter #174144, the center hole is 1 inch the canister is 4 inches in dia will this unit fit?
A:
Sierra cannot give dimensions, they can only match up by application. This is not the correct filter for that OEM number. The correct replacement is part 18-7846.


Q:
Will this filter replace Volvo 3862228 ?
A:
No you will need 18-7989.
