I have a pair of 2001 Merc 496 Ho engines in my boat. Having problem with the boat bogging down due to debris inside the fuel tanks, looks almost like fine sand.
Donīt have the cool fuel 3 module.
I only have a Merc spin on fuel filter after the Boost pump. Read that in prior years, Mercruiser did not recommend primary filters and as a result boost pump screens are being clogged by debris.
Seen boats with these engines use a primary fuel filters mounted along side the stringers before the booster pumps, small cylinder type Mercruiser 35-864572.

First, any advice to clean out the fuel tanks, limited access, only fuel pic-up and the hole for the fuel sending unit. Have pumped them out so they are empty. Any special cleaner or acid I should ad or? then try to flush.

After this have been done I am thinking of installing Racor filters as a primary filter, have anyone done this? which model?

Thanks

I thought I had a problem, turns out I didn't but I researched the solution. I pulled the fuel level sender for access. looked in the yellow pages and found a tanker truck tank cleaning company. They didn't give an exact price but said it would be under $70 to completely steam clean the tank.
