Anyone here run the Buck Algonquin mesh screen strainers and ditch the internal perko/groco type?

I see some people are fans of that approach.

I searched old threads and see a fair amount of guys run these...do you have to clean them out mid-season or do they last the Summer without fouling? Only downside is access to clean them.

Boat will be in Pen Bay and Merrimack.

Thanks all.

I've had a south bay for years, never even bother to open the in-line Groco anymore. South Bay catches everything. Doesn't need to be cleaned as everything falls off, however when the boat is hauled I pull the screen and give it a muriatic soak, the holes will get some growth and reduce the flow through the screen.

All the ocean yachts out there are built this way since '77. They work fine and "self" clear with big water hungry Detroits in them.

You can always flush from the inside if needed but 30 years with our old boat we never needed to.

Had these strainers on my 1998 twin 370 Blackfin Combi.
Have one on the 25 T Jason and the 27 H&H refit will have one.
No BIG strainer inside the engine room.


Same as mentioned above, ZERO issues and yes I slide the screen out every year, wire brush the tiny holes, recoat with light film of bottom paint, "grease the slide ins" and go boating !

Are you guys using the regular style screen with holes perpendicular to the surface or the positive flow screen with holes drilled on an angle to enhance flow rate?

I called Buck Algonquin cause I have a regular screen I’d like to use ... they said most boats use the regular screen and the positive flow is geared toward high speed rigs.

been using one for 24 years without any problems. I also pull the screen once a year, clean out the holes and put down some fresh bottom paint.

I use one as well but still have the inside strainer. The inside strainer just makes it so easy to flush and winterize the engine. Sure you could do it another way but the inside strainer also allows you to see the flow of water if there was any doubt.

Mine are square to the surface not angled. Guessing like 100gpm at cruise since its like 40-50 at idle

I have both. Only thing I use the inside strainer for is winterizing and running off the hose.

I have both on my boat as well and the inside Groco stays clean all year. Only exception is small shells I find once in a while on the inside strainers.
