If you're talking Merc, then all parts have a 12 month warranty. Not only that, but if they fail and damage other parts in the process, they're covered too. And that's not just for dealer installed parts either.. It's everybody. Don't think you'll find that on 'after-market' parts....
Shot a fuel at WOT bug outa my 150. Turned out the Sierra replacement bayonet connector couldn't deliver enough fuel. Could have toasted the powerhead.
1992 merc. 9.9...New sierra impeller.....tips broke first trip out. Thank god I cought it from the water spitter. I tried to save $4.00.....Almost cost me the engine...
Why do after market parts very seldom fit properly or fail fast.....how do thay stay in buisness?????
