    Temp gauge reading 210

    Ok. I get it. Lol. Thought i was being smart changing the sensors while i had the thermostat housing removed. I figured since no alarm turned on it must be the sender. If it was really running at 210 wouldn't the sensor read that and trigger an alarm? The sender just gives the temp reading to...

    Temp gauge reading 210

    Hi everyone. 2008 starcraft i/o 4.3l mercruiser My temp gauge is reading around 210F. There is no alarm sounding. Risers feel cool to touch while motor is running. Water feels like its flowing well through all pipes. I recently installed a new impeller ran it on the muffs before the lake and...

    Lower unit pressure test

    Hi all. 2008 starcraft I/O 4.3L merc. I am wondering if I can do a pressure test on my lower unit while its mounted on the boat. I redid some seals and a new impeller this spring because there was a little bit of water in the gear oil. After reinstalling it on the boat a friend asked if i did...

    TKS Ignition system hissing/sucking - not working properly

    Hey FT thanks for the link. Do you know if these fuses are sealed on the bottom? Does it matter if they're open or closed I haven't been able to source mini blade fuses that are closed on the bottom between pins. Do they need to be sealed if inside the waterproof fuse holder? Thanks

    TKS Ignition system hissing/sucking - not working properly

    Update. After replacing the thermostat and wiring up the new diode the TKS system is running good again no more hissing noise after warmed up for 10mins or so. Very happy the issue has been resolved. Thanks again guys. You guys have been very helpful. Now I just need to figure out the 15Amp...

    TKS Ignition system hissing/sucking - not working properly

    I'll be doing the work and running the boat on the driveway. Time to put her to sleep for the winter..... :( This is my only weekend I have before life gets too busy and the days get too cold. Any issues doing all this on the muffs?

    TKS Ignition system hissing/sucking - not working properly

    Hey alldodge, Do we know if temp switch is bad if thermostat not working (engine too cold) does your test work if thermostat still no good or is this test based on thermostat getting engine up to 160. See my last post to FT.

    TKS Ignition system hissing/sucking - not working properly

    Hey FT, yes I realize now my wording was wrong for the diode, alldodge said the same thing, all I knew was that it had no continuity both ways as stated in the post which means open. I just said shorted because it looked burnt inside. Can I edit that post now I can't find a way to do so. Would...

    TKS Ignition system hissing/sucking - not working properly

    Sorry FT you lost me. I haven’t mentioned any damaged wires. I uploaded a pic of the 15Amp fuse that is blown. It has a pink wire and a red wire with purple stripe. Where do these wires come from relate to? Alternator? Previous owner had the starter replaced. Would the starter be part of the...

    TKS Ignition system hissing/sucking - not working properly

    You mean jump the diode plug don’t you. Lol I feel stupid now… Why am I removing the fuse btw? Lol I almost understand this system… stay with me. Here’s a pic of the 15Amp fuse behind engine. Pink wire & red wire with purple stripe.

    TKS Ignition system hissing/sucking - not working properly

    Oh great thank you I will definitely try this. So when you say jumper what do you mean exactly. Point A to point B. Sorry dumb it down a little for me lol. And if the hissing goes away then the fix is new diode and thermostat? Is this what you’re thinking. Sure hope so!! I’ll be so thrilled...

    TKS Ignition system hissing/sucking - not working properly

    No worries. I’m no mechanic and appreciate the help. When I Said in my original post that the diode looks like it shorted I just didn’t have the lingo proper lol. But I did say it had no continuity multiple times and eventually corrected myself with reference to the bulletin and your wiring...

    TKS Ignition system hissing/sucking - not working properly

    The diode is open. will not allow current to pass either direction. I'm leaning towards temp switch... I tested the TKS module it DOES fully extend. I measured it cold and measured it warmed up and measured the passage it goes into and with the amount it extends the passage would be blocked...
