30 gph v 60 gph Honda 150

[sjhantzis]

Catleen came with a 30 gph fuel/water filter but it looks like 30 gph is not recommended for 150 HP engines. I bought a 60 gph Racor to swap out for the 30 gph. Any downsides to going big?

If your 150 is sucking 30 GPH, time to check the engine. But bigger shouldn't hurt a thing. Where did the "don't use a 30 with a 150" comment come from. I'd make a quick call to a servicing dealer for your engine and double check before spending more money and drilling new holes.

Your 150 at max power will use about 11 to 12 gallons an hour--more realistic is in the 6 to 7 gallons an hour.

If you get too big a Racor, it will not work properly, with the "turbo" action to separate the water. I would stay with the 30.

This is what the Honda site says for the 60 gph filter:

60 GPH Racor Fuel/Water Separator Assembly
BF75/90, BF115, BF135/150, BF200/225/250
06177-ZW1-801AH

The Honda 30 GPH filter doesn't specify. Also, I was interested in a new clip on Parker filter but the site said the 30 GPH version was not recommended for 150 HP outboards. Honestly, I never saw evidence that the old 30 GPH was limiting the performance of the engine. I suppose a larger filter will mean it doesn't have to be changed as often? Always a puzzle.

I was thinking of the diesel filters when I mentioned the turbo action--in looking up your filters, they do not have this feature. Thus you should be fine with the 60 if you wish. I have used the 30 with 130 to 150 hp engines of a number of years, with no problems. As for changing them less often--you do want to drain the bowl regularly--probably each time you fill up with fuel--some drain the bowl every time as part of the engine check--visual, check the oil, etc--drain the filter bowl. I am not sure it would decrease the change interval--I still want to change them every hundred hours.
