  1. Re: what do I do before cranking up a 115 opti that was sitting a while

    ok so should I pull the injectors and have them cleaned? It sounds much better at 1500 rpm, but I don't want to risk taking it out on the water till I am 100% sure it is cooling and burning and...
  2. Re: what do I do before cranking up a 115 opti that was sitting a while

    oh crap... I will get it out pronto... is it the ethanol in it that destroys the injectors... seafoam can says that it is for cleaning fuel injectors. All over the forums people have said to use...
  3. Re: what do I do before cranking up a 115 opti that was sitting a while

    Re: Mercruiser 3.0 Thumping in exhaust

    Re: Mercruiser 3.0 Thumping in exhaust

    ok, here are the results of the compression test:

    #1 170
    #2 just over 160
    #3 170
    #4 same as #2

    Re: Mercruiser 3.0 Thumping in exhaust

    should I test cold or warm? Also of the piston broke it would have been much louder, no? and how would it run at all? Also there would probably be a boat load (worst pun ever) of blow by?

    Thanks

    Re: Gauge & Sending Unit Questions

    What this test shows is that there is no filtering inside the gauge slowing the movement of the needle, so it seems like the gauge is ok. The only thing i can think of is that this gauge works...

    Re: Gauge & Sending Unit Questions

    +1. The fact that the resistance is too high might cause slow movement, but if you think about it it shouldn't. operating the sender halfway should make it 0-90 ohms, right? Does it move faster when...
