87 200 merc water pressure guage

[ross]

i recieved in the mail 2day my water pressure guage. it is a teleflex kit. the instructions that came with it are very vauge as to where you hook it up at the motor! there is no 1/8 inch threaded hole or a cap on either of the heads. anyone hooked one of the up on an 87 200 merc?

There should be a brass plug either in one of the heads or on the top of the block. It may be painted black but it's there.

is there a chance it could be bigger(1/2-3/4)inch and i would have to use a reducer?

 

[groucho]

Well anything's possible but I'd say that's unlikely. Unless somebody had a reason to drill out that and re-tap that hole ( why?) I've not seen a water pressure plug that large.

Slow down and look again. It's there.

a very good chance.....on the top of motor.




mine has a line from the popet valve, but yours should just have a plug.

yes sir! right in between the two banks....... i would say it's closer to 3/4 inch. where would i get a reducer for that? down to 1/8 inch?

take it out, go to auto store, and get an adapter......take the fitting that goes with gauge also to save your self an "extra trip"

they are not very good pics but this might help!

does this motor have a water-bypass hose? it says in the instructions that if it does not than a 1/8 female pipe by a 3/4 male pipe reducing bushing is required....... or a 22-36492(adaptor) from the local merc dealer.

 

[kct11]

just screw, with an adapter, into the pluged hole in your pictures. no worries, your done with that part.
