Re: blackmax xr2 not peeing at idle normal?

Well, I got a little smarter this morning and thought a second.. I took thermastat out of starboard side and hoked up to muffs and fired her up.. water came pouring out.. so im sure impellar and pumps workung.. I tested thermostats on stove and the open up.. so im sure its not overheating... dumb question, does heated water exit and other way other then the peehole? Also, I boiled water in pan then took out to boat and put overheat sensor in hot water. Took it out of water and tooched end to grund and nothing happens. Im not leaving sensir in water long enough, or something, because sensor should be setting alarm off right?

Just one of tha reasons for a pressure gauge! Throw tha sensor away and get a new one..........Done!

Yes it does. Thru tha block, adapter, down housing, out tha bottom. Look at it when its runnin' There should be a ton a water out tha bottom. You should have a heated mist comin' from tha two slots on tha back also.....

1st.

Something for your book Wired..... Tha 3 wire sensor for tha efi was an "option" on tha original efi's. Cost ya an extra hundred ta have a temp gauge sender wire.

Great. Thats all I need is more electronic stuff I dont need. Glad I only paid $39 for it.

One good thing, it that it can be used on a carb motor for "just tha gauge part".

Like you did, it can be bought cheaper on some "used" parts site cheaper than a regular "gauge only" type sender...........

Ok.. where do i find a resonable priced water pressure gauge and how do you hook it up?

Re: blackmax xr2 not peeing at idle normal?

Look all over tha internet. 0 ta 30lb. You'll find all kinds.

On top of tha block, right behind tha flywheel, you will see a pipe plug. Pull it out and adapt tha opening down to whatever size tubing that will come with tha gauge. Tha finale "bib" will need ta be a 90 degree fitting................

DukeDog.. How do you test thw actual overheat sensor? Its got power all the way to the round sensor in spring. How do I test it?

Re: blackmax xr2 not peeing at idle normal?

Don't remember ever "testin'" one. Never had to. All I always check is tha buzzer by groundin' tha wire in tha harness. All this time I've never had one fail that I remember. What Sam was sayin' 'bout 'em just isn't true. They very rarely fail. I know of NO ONE that has had one fail. That's not to say it won't happen though. One thing I do do with a part I'm unsure of I junk it. Not ina drawer, not on tha bench or sittin' ona shelf but in tha trash. No more worries..............

Sounds like you have tha earlier type (exposed spring, 2 piece head type). Only thing I remember 'bout those is tryin' ta get 'em out without screwin' it up. I usually got over anxious and pulled tha wire out!!!

Sure someone on here knows how though. Gotta go. Blue Angles fixin' ta practice......................Later.

@Duke,

The overheat/alarm sensor is probably fine forever'ish, it's just bi-metal and rarely gets used BUT.........Well, I'll put it this way perhaps and it will help, is your negative battery terminal clamped w nut and bolt on the post or pushed on and held in place with a spring in order to make/maintain a good connection? And in a critical sorta need, which type of electrical connection would you trust more? The clamped/screwed on connection or the spring pushed on connection?

Moreover..........if the connection to ground is deemed if'y(IMO, it is) and you have an overheat situation and the sensor closes as it should, how do you know you overheated? You don't!! Well a smoking motor tells you eh? Further more, If the ground is deemed if'y(same as above) and the sensor fails in the shorted mode, how do you know it failed? You don't, that sensor can sit in the block down in a crusty/dirty un-grounded hole for 23 flipping yrs and be bad/shorted and if it's not grounded by this flaky at best grounding scheme, you'll never know and it doesn't even function!!.......

The ground of that sensor is a critical path for the system to alarm you of an overheated engine and/or shorted out/fail sensor, I have NEVER in my career have seen a critical path(life support or machinery telemetry or what have you) electrical connection pushed in place and held with a spring to maintain a imperative electrical connection.........sry, just poor design IMO.

13536A 6 is starboard 3 wire sensor is a $25-$30 part. I have no doubt the dealer quoted the other guy $80 because thats what they do but in checking my records I found I paid $26 New in wrap from that "other " mercury parts site. If I can figure out the ohms rating on this thing I'll have to install a temp gauge.

Re: blackmax xr2 not peeing at idle normal?

Tha design evolved as did all tha parts on these motors but in your infinite wisdom when you and uncle "Carl" decided ta sit down and build this outboard motor ya shoulda brought that up. I'm sure they have some real "dumb asses" workin' at Merc...........mechanical and electrical.....

There is always a better way ta do it but if what your producing works leave it alone till ya develop something better which is what they did and still do..........jmo

If its get all crusty, dirty n nasty then that's on you, not tha manufacture. As long as tha "rubber" is good it will stay sealed and not get that way in tha hole.......Simple, take care of your sh1t and it won't happen........Have a nice day.

Taken care of Duke, taken care of.................And when the heck did uncle Carl get out?

Re: blackmax xr2 not peeing at idle normal?

Alright guys.. I really really appreciate yalls info.. yall have been a big help.. in a nutshell, water is reaching top of heads, it is warm coming out bottom of prop, so im sure im not overheating, .. I changed the thermostats today, I boiled them and they were opening up, but by the looks of them, I did as dukedogg would do (trashed them) I got some new ones.. lol.. im gonna head to lake saturday when it stops raining and try this puppy out.. hopefully she will start pissing... I might tackle the water pressure gauge next payday... lol..
