If I promise to seal them up cleanly with some epoxy, how big of a no-no is it to drill as small as possible holes (4) in the bottom of a starter motor for a 77′ 35 hp evinrude? This being done to insert wires to hold the brushes. Or, is there a tool to hold the brushes down and in place as one reassembles the motor?
Or, is there a cool trick to it?
And, is it okay to use oil seals from a mail order catalog that may or may not be designed specifically for outboard use? Assuming they fit as they should.
My concern is the psi rating.
The ones I see are rated to hold 10 psi.
Have no idea what psi I’m dealing with in a typical old classic omc 5-35 hp gearcase, water pump or powerhead.
Also, if it’s legit to use them, does the labeled inside diameter have to be same as the actual diameter of the shaft it’s to fit around or should that labeled inside diameter of the seal be smaller than the shaft to be snugly.
For example, the propeller shaft is 3″ diameter. Should the labeled inside diameter of the seal be 3″ too, or like 2 and 63/64ths, or some such number smaller than 3″.
Or, how bout this, is there a resource that will tell me that a cd-12 requires a prop shaft seal with 5/8 I.d. And a 1 1/2 o.d.?
The reason I ask is because I’m getting into just diving into motors and trying to get them going with out having to take them apart, figure what all I need, order said parts from Jeff, then wait a week and a half to put it all back together by which time I’ve started another one and mixed up parts….yadda yadda yadda.
I’d like just to get a butt-ton of them in varying sizes and just have them and grab them.
Same goes with spegetti seals, but I’ve already ordered like 400′ of that so I’ll learn soon enough.
Hmmmmm
Shore would know I’ve got the right one if Jeff sent it.
Hmmmm
