1979 Johnson Seahorse 4 h.p.<br />Modle # 4w79d<br />Im looking for a new 3 blade prop? I tried iboats but they dont seem to have anyhthing for an outboard that small. I have a 2 blade now but it doesnt seem to be doing very well. motor is on a 12' flat bottom aluminum jon boat. me, boat, and equipment would weigh around 450 to 500 lbs. any help would be great.<br /><br />Thanks,<br />Suzuki40
