pee hole relocation help

Can any-one help me with this? I have a 1994 50hp Johnson, the ignition died so I got new replacement parts. Along with the stator from cdi is instructions/service bulletin for moving the pee hole from bottom of engine to the top to prevent air lock in the water jacket which causes overheating.
I drilled hole in the EXACT spot they specified .540 deep and it does not intersect with any passages . So I quit at this point. So has any-one-else run into this problem motor is model #Johnson J50TLERE.
 
Moving the tell tale applied to the 3 cylinder motors.----Not sure how you did this on a 2 cylinder model ?-------- any pictures ?

I'm finding this out know. cdi website states it is for 60 hp and up. but that is not on the instructions they sent me. I guess it is a typo error. it plainly states 50hp up on paperwork.

Lesson Learned. I'll put a plug in he hole and count my blessings that I did not hit anything.

Thanks every-one
 
You can add a fitting between the lifting eye and the head but i would pull the head first. That way you can vac out any shavings just be sure and install a newhead gasket. That puts the fitting in the water jacket where any air gets trapped before it hits the thermostat. All you need is about four good threads for the fitting using a 1/8 inch pipe thread tap so just run the tap in slow and check it with the fotting then put loctite on the threads for final assy
 
I can see where the confusion happened. OMC made a two & three cylinder 50hp.
No need to relocate the pisser on a two cylinder (as you found out). By adding it to a late model engine (Kim) you have now circumvented the thermostat. The motor will run cold or at the very least cooler. Not a good idea. Just my two cents. Depends on the water it's going to be operated in.

OK if you say so it must be true.
 
I am sure he is correct i added one to my 1961 40hp lark III and it holds. Steady 145 degrees. I put a restrictor on the lower engine cover and get a strong steady stream. Just lucky i guess.
 
Kim; didn't mean to imply anything? Just depends on style of motor. Older technology motors are more forgiving at running colder. Lots more fuel & oil going into those motors. Of course it depends on where you access the port also. A restrictor at the end of the hose makes a difference also. The more water you let out, the more comes into the powerhead to over cool the motor. Most DIY guys won't think of that. They just want an indicator so they can see their water pump working. No offense meant.
