    How much trim?

    I don't think so, its just a U-joint . If that was the case we couldn't/shouldn't drive our trucks in the rain. I will be able to verify in a few days as I ran it like that all summer and am going to pull it apart soon.

    How much trim?

    I don't have a manual, used boat so that is what I am doing this summer like you said under 1000rpm and I can hear it sound off if the drive is too high. I know I have a small leak in the bellows so this winter I will pull off the drive to change them and give a good inspection and that will...

    How much trim?

    I will have to check the shifter, when I got the boat it was a disaster and the leg wouldn't go up so I bypassed the limit switch to get it to lift and then set it so it doesn't kick out until all the way up, Maybe it is in the shifter, I will check and let you know. Thanks

    Trim pump

    I don't think this is correct ( trim fluid should stay the same level), an extended cylinder should always require more volume than a retracted cylinder. Just speaking from a hydraulic standpoint. I run a crane that when its down the tank is full but extended it the fluid goes below the sight...

    Prop change rpm gain?

    How much trim?

    @Chris1956 thank you I am just concerned with idling out of the shallow boat launch and wondering what the maximum height to idle ( less than 1000 rpm) without hurting anything was. When cruising I cannot overtrim as it porpoises before it clears the support brackets. @Bondo, this boat only has...

    How much trim?

    I read somewhere the maximum I am supposed to be able to run my leg up on my 4.3 Mercruiser Alpha Gen+, can anyone tell me or show me a link to where I can find the information. To be clear looking for how high I can trim the leg engine running when idling around the shallows.

    Power steering , worse when running

    For anyone who reads this and wonders what the issue was, it was the steering cable. It was too stiff and also too long for the boat and when I did some work on it I changed where it was in the boat and this affected the way it was actuating the power steering , it was almost like it was working...

    Power steering , worse when running

    Fluid is fine, fresh and full. Pump is new and tested. Speed has no affect. The difference is steering gets harder when the engine is running and the pump is turning than when the engine is shut off. It's obvious the P/S isn't working properly but I was wondering if anyone had this particular...

    Power steering , worse when running

    I have a 1996 4.3 Mercruiser , I have been reading a few threads with similar but not exact problems to mine. My steering is fairly stiff but becomes worse with the engine running. The pump is new and I have flushed fluid through the lines until all the old fluid was gone and only clean fluid...

    upgrading the ignition in my 4.3 Mercruiser

    Thanks for the info alldodge. I got the new setup wired in and she seems to run pretty good.

    upgrading the ignition in my 4.3 Mercruiser

    the module is wonky, it has fried the tach and will not go to base timing and the low oil, high temp alarms go nonstop.

    upgrading the ignition in my 4.3 Mercruiser

    @alldodge, thank you very much for the schematic, unfortunately it isn't the same as mine. The wires from my module are clean and easy to tell the colour and I don't have a tan or a yellow wire. What serial number should I be posting? The one from the boat or the one off the engine? Actually I...

    upgrading the ignition in my 4.3 Mercruiser

    I am upgrading the ignition in my 4.3 merc, its in a 1996 Larson. I am having a hard time finding a wiring diagram for it. I need to what the wires off the original ignition module plug do. The wires in the plug are in a single row and are as follows. 1) Grey, 2) Black, 3) Purple, 4) White/Red...

    Base timing doesn't change grounding purple/white wire

    I am thinking the same which is why I suspect the module as it seems to be the control for the sensor. I will go over the wiring again though to be sure. Thanks you

    Base timing doesn't change grounding purple/white wire

    the alarm get louder when it thinks the bottle is empty, good suggestion though thanks

    Base timing doesn't change grounding purple/white wire

    Purple wire is not shorted to ground nor is it open circuit (4k ohms). Sounds like it could be the module even though it does advance as it revs up. Not sure what else it would be. The tach doesn't work so that could be another module indicator as wiring all seems correct. Also and I don't know...

    Base timing doesn't change grounding purple/white wire

    No I don't have knock sensors. I had the engine off before grounding the jumper and checking the timing as per the procedure. I will check to see if the purple wire is grounded that is a good suggestion. I will also trace it as it seems more likely that it may have an open. Also want to add that...

    Base timing doesn't change grounding purple/white wire

    Looking for help timing my engine. I have a 1996 Mercruiser 4.3 LX Gen+ with the thunderbolt ignition. Bought it with a split block and just finished installing a new engine. Have it running and got it up to temp and idling nicely. I grounded the purple/white wire to set the timing @ 10 deg and...
