Evinrude, 1987, 4hp, 2 cylinder, 2 stroke/cycle.(Excel Belgium variation?). Model no BE4RCUD. Serial no. B1547926. Re nylon hub, the nylon is split but still secure on its stainless bush. Being totally captive when in situ in the propeller boss, I feel it does not present a problem in use. Opinions/advice please. Plus can anyone suggest the cheapest source for parts. I'll have to sell a kidney to fund parts in the u.k. Thanks in anticipation.--- Al.
