Old-School D-I-Y boater rebuilds 1990 90HP Mercury Outboard

Blown Crankshaft Bearing? No Problem!

Dear MarineEngine.com,

Enclosed are pics of my 1990 90hp Mercury Outboard. Last summer after many years of use, the lower crankshaft bearing failed.

 Upon complete disagreement with my friends who wanted me to discard the engine and buy a new one I was bound and determined to rebuild this one!!

 Thanks to MarineEngine.com, I was able to rebuild my favorite outboard!! Thanks for providing a great parts source to us Old School boaters!!

 Sincerely, Louis,
Higganum, CT


Louis used his motor serial number to bring up the correct drawings and order parts.
He ordered a gasket set, connecting rod, piston, rings, seals, and other miscellaneous parts.

An old-school, do-it-yourself boater and wrench-twister, Louis tore down his ’90 Mercury, overhauled it with parts from MarineEngine.com, and put it back together again. The results? The wake in the photo says it all!
