1959 evinrude 10 hp golden jubilee lower crank shaft seal

[Captnzila]

how involved is changing the lower crank shaft seal ? im assuming the lower is crusty as the upper was basically burnt ? and if a plug is fowled is it reuseable ? whoever had this motor really cooked it good! idk the circumstances but im sure they smelled it cooking it was leaking from every lower seal ,waterpump and thermostat took an hour to clean ! also if the thermostat isnt working will it let in enough water to operate withotut cooking? in a car ive drilled holes in the old one cause it was winter and needed some heat until i could replace it? thanks ! Btw Im a master plumber if anyone needs any help there with questions lol!

Powerhead has to be removed and the mechanical seal is right there to change.

guess owners manuel would be a start this wasnt even my engine at first a friend payed 100.00 @ an ESTATE sale witch is basically a well organized overpriced garadge sale lmao! but now after getting intimate with the bottom and another150.00 and 20 hrs on forums and rebuilding her im falling for her ha ha! this motor very well made its like art !most parts are availiable thru omc surprised! he also bought a 1983 merc 3.5 hp and the parts are NA! crazy both motors were pretty well overheated ! before i exposed the top crankshaft seal i seen the coast of the replacements 38.00 not realizing there wa a replacment o ring inside the 38.00 the seal itself ! glad i didnt CAVEMAN the old one like i read others doing ! maybe the advice given they were thinking of the oilseals for the lower end those two u have to tear out ! thanks again iboaters!
