    Shifting system

    Why does my boat shift perfectly in the driveway but, in the water, no go. Now.? Reverse only and won't come without killing the engine. No forward st all.

    Shifting system

    I didn't replace that one...nor did I change its adjustment. Just the 2 (throttle & upper shift) cables were replaced. But, I'll take a look. Thanks.

    Shifting system

    I installed a new throttle/shifting control box on my 1997 Mercrusier Alpha One with 4.0 v6. It works "perfectly" in my driveway. I put it in the water. Start the boat. From neutral, put in reverse boat travels back. Shift to neutral? Remains in reverse. Shut down. Restart, in neutral. Put in...

    LOL...So, I have time adjusted a few old school engines. No marine power plants. All old style point & rotor systems. And, it's been a while. What I've seen & found otherwise is timing this engine is quite a science. In the end, with this effort, I have not changed a thing other than the...

    Well, as I said, the quarter inch counter clockwise turn was under significant resistance and it was physical stopped from any significant change. I put it back where it was when the boat ran fine. The resistance was enough to keep the distributer in place with engine running. So, as it's back...

    Just ordered a new sensor. Every body part I can cross is crossed for luck. Arrives next week. Amazon.

    Got it. Bolt was snug but slightly loose. Since motor ran good, & distributer twist was stiff & minimal, it's back where it was running good & I can forgo timing...for now. Thanks for the support. More to come...I'm sure.

    What is ignition sensor...in the distributor? Something under the cap? Or is it the Ignition Control Module on exterior of distributor?

    Anyone have one kicking around would let it go? Question ;- how can I test the module to assure it's nonop...or not? While I wait, gonna repeat & concentrate on potential wire compromised.

    Not at all what's intended. It's just another guess re: non op. Old coil was 1997 vintage. 25 yrs old. Didn't fix it. Distributor is in original operating position. Twisting is met with resistance. It doesn't twist loosely.

    Is this a proper replacement for 392-805570-1?

    Well, with new coil...nuttin. now, we'll check for spark & fuel flow. FYI...my old coil wire...connector was packed with gunk. Didn't seem to be grease. Was soft malleable gunk. I cleaned it out. Was this a mistake? Is the coil end connector purposefully packed with some sort of conductivity...

    I'll get it done but, the boat has been running and not bad at that...with the "floating" distributor. I've run it several times this season. I changed the fuel filter/ water separator and it started right up & ran fine. Then? It just decided to not start. We've "freshened" all that we can with...

    And yup...I suspected it isn't normal. I'll have to contort myself & blindly fish around for the hold down clamp. And thanks (you & Lou) for the feedback.

    The whole distributer is moving.

    When I grab my distributer by the cap, I can turn it counter clockwise bout 1/4 inch. I can turn it back (clockwise) the 1/4 inch. I've loosened no bolt or screw. Is this a normal boat/marine feature? Is it an automatic timing advance feature governed by performance loading? In my distant past...
