You might want to try installing a good quality filter in the line prior to the pump to eliminate some of that clogging.

yes, any appropriate size pulse pump will work.
Here is a '55 10hp Johnson I put a fuel pump on. These pumps are cheap, too (about $10).
Here is a '55 Johnson 25hp. It is hard to tell but this is a slightly larger pump.

sorry to ask so many questions but im relatively new to outboards. ive been a big truck mech.for quite some time and know the fundamentals. i am a current owner of a 2003 briggs 5hp air cooled(loud pos) 1957 mark 10 (money pit) 1969 merc 75(good lil runner) and my newest one a 1966 18hp fastwin. any advice / tips on these motors would be greatly appreaciated.

I think the pump is listed as a replacement for some briggs stuff, some kind of yamahammy stuff as well.
as far as tips for the other motors, what kind of issues are you having? I don't know anything about mercs, but I am sure someone here does.

The 57 mark 10 is a non issue until I find a hood and the 18 hp fastwin just needs electical components. Now my boat on the other hand is a 1973 delhi 1636 that is about to get a rebuilt and raised transom and a front deck beginning here shortly.

Cool deal!
You'll have to be careful with that pump though. The purists will tell you it does not say "marine" use on it, so it probably wont work. :LOL2:

Dang right it will I ran 3 gallons thru her today at the lake she ran like a top. Now just waiting for my head gaskets for my fastwin got the carb rebuilt and all spark producing parts changed. Cant wait to see what 18 horses will do with my girl

yea, that will be a good one. I need to get one in the 15-18 range. any bigger/smaller will not work well for me.
Last 2 I bought were a 20hp and then a 2.5hp. haha
one of these days I am going to find that old bargain in the range that I need.
