Re: Stus-List Raw water intake fouling A4
External strainers are rare on sailboats because of drag. I have no strainer inside or out. I rarely have issues, but one a FISH made it all the way to the water pump and got stuck there.

Stus-List Raw water intake fouling A4
Barbara, I don’t think I want to add an external strainer, I would be concerned it would only further the fouling issues I have. I have pretty well convinced myself to remove the elbow (seacock is a new Groco FBV) and replace with a straight 3/4” fitting to 1” ID hose to a strainer and then to the engine from there. On another note, I would be interested in what upgrades you have done to your A4. Thus far mine has electronic ignition, the big Racor fuel filter, the smaller fuel polisher form Moyer and a carb rebuild. Once the raw water strainer is added I think I should pretty well be there. It seems to run pretty good so far but we just got the boat last August so I am still learning it. Our previous boat had a diesel.

Not ideal but it is what it is. If you can change it to a straight, I'm sure that would help with the flow, but any Groco filter that will fit your space should be a good improvement for catching jellyfish, grasses, etc. The canisters are clear and you can see any debris that collects in there. At your next haulout, you may consider adding a strainer to the exterior of the hullside inlet. I don't have one, but it couldn't hurt. Many of the owners here have converted to diesels but Moyer Marine has an awesome forum for A4 owners. I love my A4, she's original to my '76 33-1 and runs like a Roman soldier.

There are different schools of thought about the external strainers. Have a look here: http://www.pbase.com/mainecruising/external_strainers. This is from the Maine Sail’s gallery.
